1. To prevent corrosion due to heating, the welding should not be too long, which is about 20% less than that of carbon steel electrodes.2. Stainless steel pipe fittings harden quickly after welding, which is easy to crack. If welded with typical stainless steel pipe fittings, it must be preheated a

The socket argon arc welding construction method has the following characteristics:1. The welding process does not require welding consumables (replaced by the expanded pipe edge). The steel pipe is inserted into the pipe fitting socket, and the socket end is welded in a circle by GTAW so that the p

Stainless steel pipe is a hollow long strip of steel, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. Stainless steel pipes are lighter in weight when they have the same bending and torsional strength. They are widely used in the manufact
