Why Welding Stainless Steel must be Used Argon Arc Welding?

Read Time:2 Minute, 24 Second

Welding stainless steel with argon arc welding for the following reasons:

1, argon gas protection can be isolated from the air oxygen, nitrogen, hydrogen and other adverse effects on the arc and molten pool, reducing the burn loss of alloying elements to get a dense, spatter-free, high quality welded joints.

2, argon arc welding arc burning stability, heat concentration, high arc column temperature, high welding productivity, narrow heat-affected zone, the welded parts stress, deformation, cracking tendency is small.

3, argon arc welding for open arc welding, easy to operate, observation.
4, electrode loss is small, the arc length is easy to maintain, welding without flux, coating layer, so it is easy to achieve mechanization and automation.

5, argon arc welding can weld almost all metals, especially some refractory metals, easy to oxidize metals, such as magnesium, titanium, molybdenum, zirconium, aluminum and their alloys.

6、It is not limited by the position of the welded parts, and can be all-position welding.
