What Techniques Should Be Used When Welding The Weld Elbows Of Stainless Steel Pipe Fittings

Stainless Steel Weld Elbow is a kind of pipe fittings, made of stainless steel, and is the main load-bearing component on the bracket. What kind of technique should be used for welding the weld elbow of stainless steel pipe fittings?

1. The arc starting method of multi-pass and multi-layer welding of stainless steel pipe fittings needs to be reflowed, and the arc pit should be filled when the arc is closed. It should be noted that if defects such as pores and cracks are found at the arcing or arcing point, the correct approach is to clean them up. It should be reminded that it is forbidden to arc or start arcs on the surface of the parent material of pipes and pipe fittings.

2. Ordinary grinding wheels cannot be used for cutting of stainless steel pipe fittings, because ordinary ones are easy to damage. The best method is to use special grinding wheels or plasma for cutting.

3. During positioning welding, the inner side of the weld of stainless steel pipe fittings should be filled with argon for protection, and the effect of argon filling depends on the size of the inner cavity of the pipeline.
