316L stainless steel capillary tube welding process using argon arc welding reasons:
1, argon protection can be isolated from the air oxygen, nitrogen, hydrogen and other undesirable effects on the arc and the molten pool, reduce the 316L stainless steel capillary tube burn, in order to get a dense, no spatter, high quality welded joints;
2, argon arc welding arc combustion stabilization, heat Concentration, high arc column temperature, high welding productivity, narrow heat-affected zone, welded weldments stress, deformation, crack tendency is small
