Brazing temperature 304 brazing temperature C. According to the inquiry brazing related information, the brazing temperature is ℃. Stainless steel pipe brazing process, air brazing requires short brazing time, low brazing temperature, reducing atmosphere furnace brazing temperature. Interface temperature of vacuum resistance brazing When vacuum brazing is used, the vacuum degree should generally reach the order of 10-3Pa. When using nitrogen or argon protection, its purity is very high, the dew point must be lower than -40 ℃. For aluminum and aluminum alloy vacuum brazed with flux other than fluoride flux, flux residue must be completely removed after brazing. The residue of the organic flux for aluminum can be washed with an organic solution such as methanol and trichloroethylene, neutralized with an aqueous solution of sodium hydroxide, and finally washed with hot and cold water. Chloride is the removal of aluminum brazing agent residue can be carried out according to the following methods; first soak in hot water at 60~80 ℃, carefully clean the residue on the brazing seam with a brush, and clean it with cold water; then soak in nitric acid solution with a volume fraction of 15%, and finally rinse with cold water. Temperature of Pure Indium Brazing Pure indium brazing temperature of twenty degrees to sixty degrees. The main process parameters of the brazing process are the brazing temperature, holding time, that is, the amount of heat absorbed. The brazing temperature is typically selected to be 25 to 60°C above the solder liquidus temperature to ensure that the solder fills the gap. What method should be used to braze diamond to braze will be better? How much should the brazing temperature be controlled? Brazed diamond can be flame brazed, high frequency brazed, induction brazed or vacuum brazed. The Ag-Cu-Ti active brazing filler metal with lower melting point is selected, the brazing temperature is controlled below ℃, the heating time should not be too long, and the cooling speed is slow.

What is the melting temperature of solder?

2023-03-04

Solder melting What is the melting temperature of solder? Tin melting point. 93 ℃, the most suitable temperature for welding operation is the melting point of the welding in use +50 degrees. The setting temperature of the soldering iron head, due to the size of the soldering part, the power and performance of the electric soldering iron, the type of soldering tin and the difference of the line type, it is advisable to increase the temperature on the basis of the above temperature. with lead solder An alloy consisting of tin (melting point) and lead (melting point). Among them, solder composed of 63% tin and 37% lead is called eutectic solder, and the melting point of this solder is degrees. lead-free solder In order to meet the ROHS standard proposed by the EU environmental protection requirements, the solder is made of tin copper alloy. What are the welding process and operation steps? 1 Five-step welding operation As shown in Figure 3-9, manual soldering iron welding, generally should follow the following five steps (referred to as the five-step operation method): (1) Preparation. Prepare the welding parts, electric iron, solder wire and soldering iron holder and place them in a place convenient for operation. Before welding, the lead wire of the component should be scraped clean, and it is better to tin-plate and then solder. The oxide, oil, rust, dust and impurities on the surface of the welded object shall be cleaned up. (2) Heating the welded parts. Place the soldering iron head at the junction of the two welds and heat the whole weldment for about 1~2s. Pay attention to making the soldering iron head contact the pad and the lead of the component at the same time. (3) into the solder wire. When the soldering surface is heated to a certain temperature, the solder wire contacts the solder from the opposite side of the soldering iron. Note: Do not send the solder wire to the soldering iron head. (4) Remove the solder wire. When the solder melts a certain amount, immediately move the solder wire to the left 45 ° direction. (5) Remove the soldering iron. After the solder infiltrates the solder pad and the welding part, remove the soldering iron 45 degrees upward to the right to finish the welding. From the beginning of step (3) to the end of step (5), the time is about 2~3s. 2 Manual desoldering technology In the production process of electronic products, it is inevitable to disassemble and replace components due to wrong installation, damage or debugging and maintenance needs. This is desoldering, also known as desoldering. In actual operation, desoldering is more difficult than soldering. If desoldering is not possible, it is easy to damage components, break printed wires and fall off pads. Especially when replacing integrated circuits, it is more difficult. Fig. 3-9 Five-step welding operation 1-solder wire; 2-base metal (to be welded);3-electric soldering iron Therefore, folding welding is also an important means of welding process. 1) Principle of desoldering The steps of desoldering are generally opposite to the steps of welding. Before desoldering, the characteristics of the original welding points must be clarified and not easily done. (1) Do not damage the removed components, wires and structural parts of the original welding parts. (2) Do not damage the pads and printed wires on the printed circuit board during desoldering. (3) for the components that have been judged to be damaged, the lead can be cut first, and then removed, which can reduce the possibility of other damage. (4) In the desoldering process, try to avoid disassembling other components or changing the position of other components. If necessary, do a good job of restoration. 2) Several common desoldering methods (1) Split-point welding method. If the two solder joints are far apart, heat them with an electric soldering iron, and then pull them out with tweezers, as shown in Figure 3-10(a). Fig. 3-10 Several common desoldering methods (2) desoldering with a tin absorber. First, the air pressure inside the tin absorber is released and jammed, and then the removed solder joint is heated to melt the solder on the solder pad. Then align the nozzle of the tin absorber with the molten solder, press the small bump on the tin absorber, and the solder will be sucked into the tin absorber, as shown in Figure 3-10 (B). (3) with a suitable medical hollow needle desoldering. The medical hollow needle is filed flat as a desoldering tool. The specific method is: while melting the solder joint with a soldering iron, the needle head is sleeved on the lead wire of the soldered component. After the solder joint is melted, the needle head is quickly inserted into the hole of the printed circuit board to disconnect the pin of the component from the pad of the printed circuit board, as shown in Figure 3-10(c). In addition, the tin-absorbing electric soldering iron is also a special desoldering soldering iron. It combines the electric soldering iron with the tin-absorbing device. While heating the solder joint, the tin is sucked into the inner cavity, thus completing the desoldering more quickly. It is often used to remove multi-pin components.

What is a welded joint

2023-03-03

Welded joint What is a welded joint Joints connected by welding are called welded joints. Welded joints include welds, fusion zones and heat affected zones: 1 weld area: joint metal and filler metal melting, and at a faster rate of cooling and solidification after formation. Weld tissue is from the liquid metal crystallization of the cast tissue, coarse grain, composition segregation, tissue is not dense. However, due to the small welding pool, fast cooling, strict chemical composition control, carbon, sulfur, phosphorus are low, but also through the alloy to adjust the chemical composition of the weld, so that it contains a certain amount of alloying elements, therefore, the performance of the weld metal problem is not big, can meet the performance requirements, especially the strength is easy to achieve. 2 Fusion zone: the transition between the melting zone and the non-melting zone. The chemical composition of the fusion zone is uneven, and the organization is coarse, which is often a coarse overheated organization or a coarse hardened organization. Its performance is often the worst in welded joints. The overheating zone (or quenching zone) in the fusion zone and the heat-affected zone is the weakest part of the mechanical properties of the welded joint, will seriously affect the quality of welded joints. 3 heat affected zone: the area where the microstructure and properties are changed by the high temperature heating of the weld zone. The heat affected zone of low carbon steel can be divided into overheating zone, normalizing zone and partial transformation zone. (1) The area above the maximum heating temperature of the overheating zone has coarse grains and even overheated tissue, which is called the overheating zone. The plasticity and toughness of the superheated zone are obviously reduced, which is the worst part of the mechanical properties in the heat affected zone. (2) In the area where the highest heating temperature in the normalizing zone is from Ac3 to ℃, the normalizing structure with fine grains is obtained by air cooling after welding, which is called the normalizing zone. The mechanical properties of the normalizing zone are better. (3) part of the phase change zone the highest heating temperature from Ac1 to Ac3 area, only part of the tissue phase change, called part of the phase change zone. The grain in this area is not uniform and the performance is poor. In the installation of welding, welding welding method is applied more. The welded joint is an uneven body formed by the local heating of the base metal by the high temperature heat source while melting and solidifying with the molten filler metal. According to the different organization and performance of each part, the welded joint can be divided into three parts. As shown in Figure 2-l, The area where melting and solidification occurs in the weld is called the weld, which is composed of molten base metal and filler metal. The area where the matrix metal is heated (but not melted) during welding is called the heat-affected zone. The fusion zone is the junction of the weld metal and the heat affected zone in the welded joint, and the one hub of the fusion zone is very narrow, with a width of 0.1~0.4mm.

What is welding rod hand arc welding

2023-03-02

Hand arc welding What is welding rod hand arc welding Working principle: The basic working principle of electrode arc welding is through the commonly used voltage or industrial electricity, through the voltage reducer in the electric welding machine to reduce the voltage, enhance the current, and make the electric energy generate huge arc heat to melt the electrode and Steel, and the melting of the welding rod makes the fusion between steel higher. The medicine skin on the outer layer of the welding rod and CO2 gas sprayed out by CO2 welding play a role in preventing the oxidation of the metal after melting (I don't believe you can knock the medicine powder to see if it can be welded). Of course, this explanation is popular. What are the methods to improve the quality of welding sheet by manual arc welding? Improve the quality of manual arc welding welding sheet, method, can choose the 2.5 diameter of the electrode, broken arc spot welding for welding, can improve the quality of welding sheet. manual arc welding profile: Manual arc welding (referred to as hand arc welding) is a manual operation of the welding rod and the workpiece to be welded as two electrodes, using the arc heat between the welding rod and the welding piece to melt the metal welding method. Manual arc welding is the use of manually manipulated welding rod for welding arc welding method, referred to as hand arc welding. Welding process: manual arc welding is composed of welding power supply, welding cable, welding tongs, welding rod, weldment and arc. During welding, the welding rod and workpiece are used to contact and ignite the arc, then the welding rod is lifted and kept at a certain distance. Under the appropriate arc voltage and welding current provided by the welding power supply, the arc burns stably, generating high temperature, and the welding rod and welding part are locally heated to a melted state. The molten metal at the end of the electrode and the molten weldment metal fuse together to form a weld pool. In welding, the arc moves with the electrode, and the liquid metal in the molten pool gradually cools and crystallizes to form a weld, and the two weldments are welded together.

What are the welding techniques?

2023-03-01

Welding technology What are the welding techniques? Hand arc welding is the earliest developed and most widely used welding method in various arc welding methods. It is coated with the outside of the electrode electrode and filler metal, the arc is burning between the end of the electrode and the surface of the welded workpiece. Under the action of arc heat, the coating can generate gas to protect the arc on the one hand, and on the other hand, it can generate slag to cover the surface of the molten pool to prevent the interaction between the molten metal and the surrounding gas. The more important role of slag is to produce physical and chemical reactions with molten metal or to add alloying elements to improve the properties of weld metal. Hand arc welding equipment is simple, light, flexible operation. It can be applied to the welding of short seams in maintenance and assembly, especially for welding of difficult to reach parts. Hand arc welding with the corresponding electrode can be applied to most industrial carbon steel, stainless steel, cast iron, copper, aluminum, nickel and its alloys. 2. Gas tungsten arc welding This is a non-melting gas shielded arc welding, which uses the arc between the tungsten electrode and the workpiece to melt the metal to form a weld. The tungsten pole does not melt during the welding process and only acts as an electrode. At the same time by the torch nozzle into argon or helium for protection. A metal may be additionally added as needed. Internationally known as TIG welding. Gas tungsten arc welding is an excellent method for joining sheet metal and backing due to its good control of heat input. This method can be used to join almost all metals, especially for welding aluminum, magnesium, which can form refractory oxides, and active metals such as titanium and zirconium. The weld quality of this welding method is high, but compared with other arc welding, the welding speed is slow. 3. MIG shielded arc welding This welding method is the use of continuous feeding of the welding wire and the workpiece burning between the arc as a heat source, by the torch nozzle of the gas protection arc to welding. The shielding gases commonly used in gas shielded arc welding are argon, helium, CO2 or a mixture of these gases. When argon or helium is used as shielding gas, it is called metal inert gas shielded arc welding (referred to as MIG welding in the world); When inert gas and oxidizing gas (O2,CO2) mixed gas is used as protective gas, or when CO2 gas or CO2 + O2 mixed gas is used as protective gas, or when CO2 gas or CO2 + O2 mixed gas is used as protective gas, it is collectively referred to as melting electrode active gas shielded arc welding (referred to as MAG welding in the world). The main advantage of MIG arc welding is that it can be easily welded in various positions, and it also has the advantages of faster welding speed and high deposition rate. Melt electrode active gas shielded arc welding can be applied to most major metals, including carbon steel, alloy steel. MIG welding is suitable for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloys. Arc spot welding is also possible with this welding method. 4. Plasma arc welding Plasma arc welding is also a non-melting arc welding. It is the use of electrode and workpiece between the compression arc (called forward transfer arc) to achieve welding. The electrode used is usually a tungsten electrode. The plasma gas used to generate the plasma arc may be argon, nitrogen, helium, or a mixture of the two. At the same time, it is also protected by inert gas through the nozzle. Filler metal can be added during welding, or no filler metal can be added. Plasma arc welding welding, because of its straight arc, energy density, and thus the arc penetration ability. The keyhole effect produced during plasma arc welding can be carried out without beveling for most metals within a certain thickness range, and can ensure uniform penetration and weld. Therefore, plasma arc welding has high productivity and good weld quality. However, plasma arc welding equipment (including nozzles) is more complex, the control of welding process parameters is higher. Most of the metals that can be welded by gas tungsten arc welding can be plasma arc welding. In contrast, welding of extremely thin metals of 1mm or less can be easily performed by plasma arc welding. 5. Tubular welding wire arc welding Tubular welding wire arc welding is also the use of continuous feeding of the welding wire and the workpiece burning between the arc as a heat source for welding, can be considered as a type of MIG welding. The welding wire used is a tubular welding wire, the tube containing various components of the flux. During welding, a protective gas, mainly CO2, is applied. The flux is decomposed or melted by heat, which plays the role of slag forming to protect the solution pool, alloy infiltration and arc stabilization. Tubular welding wire arc welding in addition to the above-mentioned advantages of gas shielded arc welding, due to the role of the flux in the tube, so that it has more advantages in metallurgy. Tubular wire arc welding can be applied to the welding of various joints of most ferrous metals. Tubular wire arc welding has been widely used in some advanced industrial countries. The "tubular wire" is now referred to as "flux-cored wire".

Automated welding What are the prospects for welding technology and automation? Second, the welding major is a short-term major. As long as you choose a good school, you don't need to invest too much time and you can get a job after studying. Dear students, we must recognize a reality. It is basically difficult to learn welding by ourselves. "You can see it at a glance, and you can waste it at a dry time." This is a common problem in learning welding. Welding is a very professional professional, want to learn must go through professional training and constantly sum up experience, and ordinary training institutions do not have the corresponding equipment and facilities and industry standard requirements, if you can not learn the real technology, is undoubtedly a waste of time and energy. What are the components of automated welding equipment? 1, welding power supply, its output power and welding characteristics should be matched with the proposed welding process, and equipped with the main controller connected to the interface. 2, wire feeder and its control and speed control system, for wire feeding speed control accuracy requirements of high wire feeder, the control circuit should be added speed feedback. 3. The welding head uses its moving mechanism, which consists of the welding head, the welding head support frame, the hanging carriage, etc. It is located in the precision welding head mechanism, and its driving system shall adopt a servo motor equipped with an encoder. 4, weldment movement or displacement mechanism, such as welding roller frame, head and tail frame turning machine, rotary platform and displacement machine, precision type of moving displacement mechanism should be equipped with servo motor drive. 5. Welding parts clamping mechanism. 6. The main controller, also known as the system controller, is mainly used for the linkage control of each component, the control of the welding program, the setting, adjustment and display of the main welding parameters. Control functions such as fault diagnosis and man-machine dialogue can be extended if necessary. 7, computer software, welding equipment commonly used computer software are: programming software, functional software, process method software and expert systems. 8.

Welding robot What is a welding robot and how is it classified? Welding robot is a kind of automatic mechanical equipment used for welding operation. It is equipped with welding tongs or welding (cutting) gun at the end of the flange of industrial robot to make it capable of welding, cutting or thermal spraying. Through teaching programming to complete the welding work, can realize the automatic welding production. Generally, the types of robots are distinguished according to the protective gas used by welding robots. There are two common types. One is the welding robot using carbon dioxide as the protective gas, which is called carbon dioxide gas shielded welding robot for short as gas shielded welding robot; Gas shielded welding robot The other is a robot that uses argon as a protective gas, called argon arc welding robot. Argon arc welding robot What are the current welding robots! 3. The welding robot is divided into four kinds according to the movement form of the arm. Cartesian coordinate type arm can move along the three Cartesian coordinates; cylindrical coordinate type arm can be used for lifting, rotating and telescopic action; spherical coordinate type arm can be rotated, pitched and telescopic; joint type arm has multiple rotating joints. The welding robot is composed of three basic parts: the main body, the drive system and the control system. The main body is the base and the actuator, including the arm, wrist and hand, and some robots also have a walking mechanism. Most welding robots have 3 to 6 degrees of freedom of motion, of which the wrist usually has 1 to 3 degrees of freedom of motion; the drive system includes a power device and a transmission mechanism to make the actuator produce corresponding actions; the control system is in accordance with the input The program sends a command signal to the drive system and the actuator and controls it. How about a welding robot? 1. Improve welding efficiency. Welding robot can do without rest, has been working, at the same time welding robot to make the reaction time is very short, rapid action, can be completed in a shorter time large quantities of work, so the welding robot is more suitable for mass welding production. 2, reduce the cost of enterprises. If enterprises want to obtain higher income, they need to ensure low-cost and high-efficiency work. The operation of welding robots can realize automatic production. Operators only need to set system parameters to carry out automatic welding work. According to the actual production situation of enterprises, one operator can operate multiple welding robots at the same time to reduce the labor cost of enterprises. 3, longer service life. Welding robots are mechanical equipment. With the continuous development of science and technology and welding technology in our country, the service life of welding robots can be as long as decades. In use, users only need to perform simple maintenance to stabilize the welding quality while extending Service life. 4. Alleviate the problem of recruitment difficulties. Welding workers belong to a special type of work, and there are relatively few people engaged in manual welding. The labor force of welding robots can offset the labor efficiency of multiple workers. In the case of the same welding task, the welding robot can complete the welding task quickly under the condition of ensuring the welding quality. Among the manufacturers of welding robots, Wuxi Golden Red Eagle stands out with its high cost performance and one-stop service, and its products are sold at home and abroad.
