Many people do not know how the stainless steel vacuum bellows are welded. The stainless steel vacuum bellows has very high requirements for the welding process; immature welding technology may cause problems such as perforation and rust of the bellows. Today, let us know how to weld stainless steel vacuum bellows together!
Stainless steel bellows welding technology is divided into TIG welding (non-melting extreme degradation of tungsten gas shielded arc welding) and MIG welding), the difference between the two is the material used in welding. MIG uses welding wire, TIG except that the welding gun uses tungsten electrode, there is no big difference between the two.
TIG welding: TIG welding has good air tightness and is mostly used for medium and thick workpieces. The welding that can reduce the pressure vessel welding is welding pores, and the heat source is DC arc.
MIG welding: as the arc medium to add gas, protection of metal droplets, welding part of high temperature metal arc welding method.
Stainless steel welding is divided into five steps.
The first step: The nozzle size is to measure the length of the pipe on the door during welding, and then use the pipe cutter to cut the size of the pipe.
Step 2: Clean the pipeline. Since the pipe is metallic, oxidation in the pipe produces a part of the waste, part of the waste affects the welding effect.
Part III: After cleaning the fittings with a tube brush, the welding hose can ensure the joint of cleaning and tinning.
Step 4: In order to master the welding time generally required for the welding pipe length, the corresponding length of solder is required.
The temperature of the inner pipe welding can not be too high, too high, the material will change, easy to rust.
The above is how to weld stainless steel vacuum bellows. As a leader in the development of this technology, stainless steel bellows are always welded by unique engineering to improve the process level to meet the strict requirements of complex power systems. Provide contract assembly services such as design, manufacturing, welding, high-level assembly, test packaging, etc. According to needs, certified cleanliness 100/cleanliness 1000/cleanliness 10000 assembly site environment can be provided. In the past, the number of turns and the shape of the formed corrugated pipe are limited, so the side welding corrugated pipe can choose a wider range of materials, so providing your edge can make your equipment better and ensure your own product needs.
