The material of stamping elbow pipe fittings needs some special materials to produce, these materials should be strictly selected and controlled, and suitable materials should be selected, otherwise the production of stamping elbow pipe fittings will not have quality assurance. The stamping materials of elbow fittings are widely used, forming a huge high-tech industry group, which has broad market prospects and very important strategic significance. Stamping materials can be divided into microelectronic materials, optoelectronic materials, sensor materials, information materials, biomedical materials, ecological environment materials, power materials and smart materials according to their performance. These stamping materials have different performance,
1. Choose a suitable welding method according to the structure and welding requirements of the welding material. For example, there is no special requirement. Since the thermal conductivity of stainless steel is lower than that of copper or copper, it can be welded with a soldering iron. Aluminum is slightly larger and has no contact. Before that, we had to use WE88C WE88C-F flux-cored welding wire to cooperate, and have this video electric welding stainless steel. If the strength of the welding structure is not high, you can use the flame heating method, using WE53 special porous The spray gun heats the object, and the liquefied petroleum gas burns the liquefied petroleum gas alone. Do not contact with oxygen.
2. High-silver VOD203 welding wire can be used for welding, with good fluidity, uniform cost and wide use. This type of stainless steel soldering time requires auxiliary vod201-F solder paste soldering.
3. Choose WE46 special filler metal stamping elbow fittings, which can replace high silver wire welding.
