Stainless steel metal pipe is a hose that everyone often comes into contact with in daily life, but do you know how the stainless steel metal pipe is welded? Let our engineers explain it for everyone today.
Stainless steel metal pipes have very high welding process requirements; if the welding technology is immature, problems such as perforation, water leakage, and rusting of metal pipes may occur.
The stainless steel metal tube welding technology is divided into TIG welding (non-melting extremely degradable gas tungsten arc welding) and MIG welding (melting extremely degenerate gas shielding welding). The difference between the two lies in the materials used in the welding process. Metal wires, while TIG uses tungsten electrodes in the torch, there is not much difference between the two.
TIG welding: TIG welding has better air tightness, which can reduce pressure vessel welding. Welding is a blowhole in the weld. The heat source is a DC arc. The working voltage is 10-95 volts and the current can reach 600 amps. It is mostly used on medium-thickness workpieces.
MIG welding: An arc welding method that uses external gas as an arc medium and protects metal droplets and high-temperature metals in the welding zone.
In addition to welding technology, the two welding methods also require the use of a mixed gas as a medium with a composition of 90% argon + 20% carbon dioxide. It can be seen that the welding of stainless steel bellows relies on technology and care.
