【Summary Description】 Fusion welding material What welding rods are commonly used for welding copper pipes and iron pipes What kind of welding wire and electrode is used for welding copper pipes depends on the size, structure, size and welding requirements of copper pipes: 1., if small-diameter copper pipes are generally limited to a diameter of less than 20mm, we can choose flame brazing or high-frequency brazing welding, then according to the requirements of brazing, there are the following kinds of welding wires and electrodes. 1) regular can be welded with phosphor copper such as welding electrodes with low requirements for frequency vibration, the heating method is flame welding, which is self-brazing for copper pipes, does not need auxiliary flux welding, and has a relatively low melting point, but has strong brittleness. 2) If the strength requirement is higher, the permeability is slightly stronger, and the melting point is close to the silver-containing welding wire, the welding material has better permeability, stronger fluidity and wettability, and higher quality. 3) If there are some requirements for strength and toughness, brass gas welding wire with slightly higher temperature, such as Viodin's welding wire, can be used, but red copper needs to be welded with copper solder paste Viodin-F flux paste. 4) If the strength requirement is higher, high temperature brazing filler metal can be selected, because the welding rod itself is coated with medicine, so welding copper does not need auxiliary flux welding. If the 2. is a large-diameter copper pipe, which is generally more than 20mm and the wall thickness is more than 1mm, it is difficult to master the uniformity of temperature by brazing heating at this time, then welding can be adopted, and according to the welding material, it can be subdivided into welded red copper pipe, as well as welding of red copper pipe and iron pipe, red copper pipe and stainless steel pipe. 1) If it is pure copper large tube welding, welding wire welding can be selected, such as red copper argon arc welding wire, DC argon arc welding, welding wire specifications can be selected according to the wall thickness of red copper. 2) If the red copper pipe is welded to the iron pipe, or the red copper pipe is welded to the stainless steel pipe, the brass argon arc welding wire of Weiodin, which is suitable for welding dissimilar copper metals, can be selected. At this time, the welding is protected by high purity argon, which is biased towards the copper side. Combining the above two types, the appropriate welding wire and electrode can be selected. In short, brazing must be as uniform as possible in temperature. If welding is used, welding wire and welding material with good weldability and corresponding welding wire must be selected.
