The material of stamping elbow pipe fittings needs some special materials to produce, these materials should be selected and controlled strictly, the material should be selected to be suitable, otherwise the production of stamping elbow pipe fittings will not have quality assurance. The stamping materials of elbow pipe fittings are complicated and widely used, forming a large-scale high-tech industrial group, which has a very broad market prospect and a very important strategic significance. Stamping materials can be divided into microelectronic materials, photoelectronic materials, sensor materials, information materials, biomedical materials, ecological environment materials, power materials and smart materials according to their use performance. These stamping materials have different use performance, showing excellent use value in different fields and professions.

1. According to the structure of the welding material and welding requirements to choose suitable welding, for example, there is no special requirements, and stick on it can use the soldering iron welding, due to the low thermal conductivity of stainless steel than copper or aluminum, so the slightly larger and no contact, this had to use WE88C WE88C - F flux welding wire cooperation before, and have this video electric welding stainless steel, if the strength of the welded structure is a little demand can use flame heating method, heating things with WE53 special porous spray gun, liquefied petroleum gas burning liquefied gas burning alone, don't with oxygen.

2. The high silver VOD203 welding wire can be used for welding, which has good fluidity but high uniform cost and is also widely used. The time of this type of welding of stainless steel needs to assist the vod201-F solder paste welding.

3. Select WE46 special filler metal for stamping elbow pipe fitting that can replace high-silver wire welding.
