Laser vision software cooperates with cooperative robot to realize automatic welding

2023-10-13

Introduction With the rapid development of manufacturing industry, the demand of automatic welding is increasing. In order to meet this demand, we propose an automated welding scheme based on the combination of laser vision software and collaborative robots. This scheme can not only improve the welding accuracy and efficiency, but also reduce labor costs and improve production quality. 1. Laser Vision Software Laser vision software is a software system based on computer vision and laser technology, which is mainly used in robot navigation, object recognition and positioning. In automated welding, laser vision software mainly realizes the following functions: 1. Object recognition: By collecting the image of the object to be welded, the computer vision technology is used to identify the position, shape, size and other information of the object to be welded, which provides the basic data for the subsequent welding path planning. 2. Welding path planning: According to the identified object information, laser vision software can generate the optimal welding path and update the path in real time to respond to changes in the welding object. 3. Welding parameter setting: Laser vision software can set appropriate welding parameters for different welding needs, such as laser power, welding speed, etc., to ensure welding quality. 4. Real-time monitoring and adjustment: During the welding process, the laser vision software can monitor the welding effect in real time, and adjust the deviation in real time to ensure the stability of the welding quality. 2. collaborative robot Collaborative robots are a new type of industrial robot that can perform various operations with human workers without additional safety guards. In automated welding, collaborative robots mainly undertake the following tasks: 1. Perform welding operations: The collaborative robot can accurately and stably perform welding operations according to the welding path generated by the laser vision software. 2. Precise movement: The collaborative robot has high-precision motion control capabilities, which can ensure that the position of the object to be welded is relatively stable during the welding process. 3. Real-time feedback: The collaborative robot can feedback various information in the welding process in real time, such as temperature, pressure, etc., and provide real-time data for laser vision software to fine-tune the welding path. 4. Adaptability: Collaborative robots are characterized by strong environmental adaptability and can work stably in different welding environments. For example, the collaborative robot can still maintain a high efficiency and high precision welding operation when facing different shapes, sizes and materials of objects to be welded. Cooperation of 3. Laser Vision Software and Cooperative Robot In the automated welding process, laser vision software and collaborative robots need to work closely to achieve high-quality welding results. Specifically, this cooperation includes the following aspects: 1. Data sharing: The laser vision software needs to share various information of the recognized object to be welded to the collaborative robot so that the robot can generate the corresponding welding path based on this information. The cooperative robot shares the real-time feedback information in the welding process to the laser vision software, so that the software can adjust the welding path according to this information. 2. Real-time communication: A real-time communication mechanism needs to be established between laser vision software and collaborative robots so that the two can work simultaneously. For example, in the welding process, when the collaborative robot encounters an unexpected situation and needs to adjust the welding path, it needs to notify the laser vision software in time through the communication mechanism, and the software updates the welding path in time after receiving the information. 3. Mutual calibration: Since the laser vision software and the collaborative robot have certain errors, mutual calibration is required to reduce the error. For example, the minimum common divisor of the two errors can be found through trial and error, so as to reduce the error as much as possible during automatic welding. 4. Fault handling: In the automated welding process, if the laser vision software or collaborative robot fails, it needs to be able to deal with it in time. For example, a fault detection and diagnosis module can be set up to stop the welding operation in time and give an alarm to prompt manual intervention when a fault is detected. 4. Conclusion By combining laser vision software with collaborative robots, high-quality, high-efficiency automated welding can be achieved. This scheme can not only improve the accuracy and efficiency of welding, reduce labor costs, but also improve the quality and consistency of production. With the continuous development of technology, this cooperation scheme will be applied and promoted in more fields.

304 stainless steel will rust after welding?

2023-10-10

In addition to iron, the composition of 304 stainless steel includes chromium, nickel, aluminum, silicon, etc. Scientists have found that the more uniform the internal structure of the steel, the more closely the various components are linked, the more difficult it is for corrosion to invade, and the content of alloying elements, generally speaking, the content of chromium in 10.5% steel is not easy to rust. The higher the content of chromium nickel, the better the corrosion resistance. For example, the content of nickel in 304 materials is 8-10%, and the content of chromium reaches 18-20%. Such 304 stainless steel will not rust after welding. In addition, a layer of oxide protective film is attached to the surface, just like putting armor on steel, it is naturally not easy to rust. Stainless steel is formed on the surface of a very thin and strong fine stable chromium-rich oxide film (protective film), to prevent oxygen atoms continue to penetrate, continue to oxidize, and obtain the ability to resist corrosion. But there is some reason, this film is constantly destroyed, the air or liquid and oxygen atoms will continue to penetrate or metal iron atoms continue to segregate out, the formation of loose iron oxide, the metal surface is also subject to constant corrosion. There are many forms of damage to this surface film, and the most common ones are as follows: 1, stainless steel surface storage containing other metal elements of dust or heterogeneous metal particles of the attachment, in the humid air, the attachment and stainless steel between the condensate, the two into a micro battery, triggered the electrochemical reaction, the protective film is damaged, called electrochemical corrosion. 2, stainless steel surface adhesion of organic juice (such as melons and vegetables, noodle soup phlegm, etc.), in the case of water and oxygen, constitute organic acid, long time to form organic acid on the metal surface corrosion. 3, stainless steel surface adhesion containing acid, alkali, salt substances (such as the decoration of the wall of alkaline water, lime water spray) caused by local corrosion. The welding process of stainless steel welding manufacturers will also affect the corrosion resistance of stainless steel. Stainless steel processing plants with good welding technology, advanced equipment and advanced technology can be guaranteed in the control of alloy elements, the removal of impurities and the control of billet cooling temperature. Welding stainless steel products has rich experience and advanced equipment, while some small steel mills have backward equipment and backward technology. In the smelting process, impurities cannot be removed, and the products produced will inevitably rust. Therefore, from the material itself, 304 stainless steel will not rust, but because it needs to be processed, whether it will rust or not depends on the smelting technology of the processing plant. Try to choose a large processing plant with advanced equipment and good welding technology.

What should be paid attention to in the welder operation specification of stainless steel welding parts?

2023-10-08

Welding is a process that connects metals together and is widely used in manufacturing, construction, and maintenance. Stainless steel is a common Welding materials, which has the characteristics of corrosion resistance and beautiful appearance. In order to ensure the quality and safety of welding, welders must comply with certain operating specifications. This article will introduce the importance and significance of the welder's operating specifications for stainless steel weldments, as well as the methods and precautions for implementing the specifications. Before welding, preparation is essential. First, make sure that the weldment meets the specifications, including thickness, width, length, etc. Secondly, it is very important to choose the right electrode and current. The electrode is a material used to connect metals during welding. It is necessary to select the appropriate electrode according to the type and thickness of the metal. Current is the energy source used to melt the electrode and metal in the welding process. Too large or too small current will affect the welding quality. Therefore, the welder should carefully check the specifications of the welding parts and electrodes before welding, and select the appropriate current. The welding process includes multiple steps, and there are many matters needing attention. First of all, clamping and positioning are very important. Clamping is the method used to fix the weldment, and positioning is to determine the position of the weldment. Correct clamping and positioning can ensure that the metal will not move or deform during the welding process. Secondly, the core is the most important part of the welding process. The welding core is the part that combines the welding rod and the metal after melting, and its quality and stability need to be guaranteed. In addition, the shielding gas is also essential in the welding process. The shielding gas can prevent the metal from being oxidized during the welding process, thereby improving the welding quality. In the welding process, welders need to pay attention to many things. First of all, explosion protection is very important. High temperature and high pressure will be generated during the welding process, which may cause explosion if not handled properly. Therefore, welders should avoid excessive heat or impact on the metal during operation. Fire prevention is also essential. Sparks and high temperatures generated during the welding process may cause a fire. Therefore, welders should take measures to prevent fire, such as setting fire barriers, using fire extinguishers, etc. Moisture is also important. The humid environment may cause the electrode and the metal surface to oxidize, thereby affecting the welding quality. Therefore, welders should avoid welding in a humid environment during operation. After the welding is completed, a quality inspection is required. Quality inspection is an important link to ensure the quality of welding, including visual inspection and non-destructive testing. Visual inspection is to check whether there are defects in welded parts, such as undercut, air holes, etc. Non-destructive testing is to detect the quality of the welding parts through certain methods, such as X-ray testing, ultrasonic testing and so on. If quality problems are found, trimming or re-welding is required. In short, stainless steel weldment welder operation specification is a necessary condition to ensure welding quality and safety. Welders must strictly abide by the operating specifications, carefully implement every step and precautions to ensure welding quality and safety. Whether it is preparation work, welding process or quality inspection, it needs to be strictly controlled and checked. Only in this way can we produce high-quality stainless steel welding parts and provide reliable guarantee for industrial production and construction. Therefore, we should pay attention to the importance of stainless steel welder operation specification, and remind the majority of welders in the operation must be careful and meticulous, to ensure that every link is in line with the specification requirements.

The characteristics of vacuum brazing technology can be rapidly developed and applied

2023-07-10

Vacuum brazing technology can be rapidly developed and applied, mainly because it has a series of advantages compared with other brazing methods: ① In the process of vacuum brazing, the workpiece to be brazed is under vacuum conditions, and there will be no oxidation, carburization, decarburization, pollution and deterioration. The cleanliness of the welded joint is good and the strength is high. When brazing, the brazing temperature is lower than the melting point of the base metal, which has little influence on the base material, the whole part is heated evenly, the thermal stress is small, and the deformation can be controlled to a minimum, which is especially suitable for brazing of precision products. The low pressure around the base metal and the brazing filler metal can eliminate the volatile gas and impurities released by the metal at the brazing temperature, which can improve the performance of the base metal. Because no flux, so there will be no pores, impurities and other defects, improve the corrosion resistance of the base metal, avoid pollution, can save the process of cleaning residual flux after brazing, save time, improve working conditions, no pollution to the environment. ⑤ The workpiece heat treatment process can be completed at the same time in the brazing process, select the appropriate welding process parameters, but also the brazing arrangement for the final process, and get the performance of the brazed joints in line with the design requirements. ⑥ It can braze multiple adjacent brazing seams at one time, or braze multiple components in the same furnace, with high brazing efficiency. There are many kinds of metals that can be brazed, especially suitable for brazing aluminum and aluminum alloy, titanium and titanium alloy, stainless steel, high temperature alloy, etc. Also suitable for titanium, zirconium, niobium, molybdenum, tungsten equivalent or dissimilar metal brazing connection. Vacuum brazing is also suitable for composite materials, ceramics, graphite, glass, diamond and other materials. ⑧ The design approach of the product is broadened, and the components with narrow grooves, extremely small transition tables, blind holes, closed containers and parts with complex shapes can be brazed without considering corrosion, cleaning, damage and other problems caused by flux, etc. (3) Disadvantages of vacuum welding ① Under vacuum conditions, the metal is volatile, so it is not easy to apply vacuum brazing to metals and brazing materials containing volatile elements. If it is really necessary to use, special process measures should be adopted. ② Vacuum brazing is sensitive to the surface roughness, assembly quality and fit tolerance of the parts before brazing, and has high requirements for the working environment. The vacuum brazing equipment one-time investment, high maintenance costs.

Application and characteristics of induction welding

2023-07-09

Induction brazing is a welding method using high frequency, medium frequency or power frequency induced current as a heat source. Its main feature is that the workpiece is heated by the resistance heat of the induced current generated in the alternating magnetic field of the alternating current. Specifically, the conductive workpiece is placed in a changing electromagnetic field, and the induction heating power supply provides a changing current to the single-turn or multi-turn induction coil to generate a magnetic field. When the workpiece is placed between the induction coils and enters the magnetic field, eddy currents enter the interior of the workpiece, producing precisely controlled local heating. Induction heating brazing is to place the brazing part of the part in an alternating magnetic field, and realize the heating of the base material through the resistance heat of the induced current generated in the alternating magnetic field. The strength of the induced current in a conductor is proportional to the frequency of the alternating current. As the frequency of the alternating current used increases, the induction current increases and the heating speed of the weldment becomes faster. When an alternating current passes through a conductor, the current density on the surface of the conductor is large, and the current density inside the conductor is small. When high-frequency current passes through the conductor, the current density difference on the conductor section increases, and the current is mainly concentrated on the surface of the conductor, which is the so-called skin effect. Because induction heating brazing adopts the heating method from inside to outside, unlike laser heating brazing, its effect is not affected by the change of brazing position or joint. Induction heating soldering can provide faster and more uniform heating than soldering with a soldering iron. The soldering iron tip will wear out and need to be replaced frequently, while the induction coils are actually wear-free because they are non-contact. There are many advantages to replacing gas flame brazing with induction heating. It can conduct more heat per unit area of material. The brazing temperature can usually be reached in a few seconds, which makes the heating cycle shorter and improves the yield.

Monitoring and control of the laser welding process is essential

2023-07-08

Laser welding is an efficient and accurate welding method, which is widely used in automobile manufacturing, aerospace, electronic devices and other industries. However, in the process of laser welding, due to the fast welding speed and high energy density, welding defects are prone to appear, such as molten pool sputtering, cracks, inclusions, etc., which affect the welding quality and strength. Therefore, it is very important to monitor and control the laser welding process. Monitoring of the laser welding process can be achieved by various means. First of all, the use of high-speed camera technology can be real-time observation of the weld pool shape and dynamic behavior of the welding process, welding defects for early warning and analysis. Secondly, the use of radiation thermal imaging technology can detect the temperature changes in the welding area, so as to determine whether there are welding defects. In addition, the change of laser and other process parameters can be monitored by sound, light and other sensors, and problems can be found and adjusted in advance. The control of laser welding process mainly includes three aspects: beam control, power control and speed control. First, beam control refers to adjusting the size and shape of the laser beam to suit different welding needs. For example, the laser beam can be more concentrated and stable by adjusting the position, angle and curvature of the laser focusing lens. Secondly, power control refers to adjusting the energy density of the laser to ensure the melting depth and molten pool shape during the welding process. Finally, speed control refers to adjusting the welding speed so that the width and depth of the weld are controlled within a reasonable range to ensure welding quality. In order to realize the monitoring and control of laser welding process, it is necessary to combine advanced sensor technology, image processing algorithm and automatic control system. At the same time, it is also necessary to optimize and improve the laser welding process, such as adjusting welding parameters and optimizing welding path, in order to improve welding quality and efficiency. All in all, the monitoring and control of the laser welding process is essential to ensure the quality and strength of the weld. By using advanced monitoring means and control methods, welding defects can be found and corrected in time, and welding efficiency and consistency can be improved. This will help promote the application of laser welding technology in various industries, and further promote the development and innovation of the industry.
