Instruction and Application: Super austenitic stainless steel tungsten electrode argon arc welding wire, low impurity element C, S, P, etc. Molten metal mechanical properties good, corrosion-resistant performance good.It is suitable for welding of stainless steel such as 904L (015Cr21Ni26Mo5Cu2) type pure austenitic stainless steel. It can also be used as surface corrosion resistance surfacing for carbon steel or low alloy steel.

Notice:
1.The welding consumables surface rust, oil and other impurities to be clean.
2.Each layer is controlled below 150℃.
3.The operation is appropriate to the short arc, arc length control in 1-3mm.
