Why can stainless steel pipes be welded by argon arc welding?
The arc welding of argon arc welding has the advantages of stable combustion, concentrated heat, high temperature of the arc column, high welding efficiency, narrow heat affected zone, and little stress, deformation and crack tendency of the weldment;
Argon arc welding arc welding, convenient operation and observation; electrode loss is small, easy to maintain the arc length, welding flux free, coating layer, so it is easy to realize mechanization and automation; argon arc welding welding can almost all metals, especially some refractory metal, oxidizable metals, such as magnesium, titanium, molybdenum zirconium and aluminum and its alloys; by the welding location restrictions, can be used for all position welding.
Argon protection can isolate the harmful effects of oxygen, nitrogen and hydrogen on the arc and molten pool in the air, and reduce the burning loss of alloy elements, so as to obtain compact, no spatter and high quality welded joints;
