WELDING TECHNOLOGY
Don't let the questions
Continue to haunt you
Arc instability
Unsightly molding
Excessive spatter
Suitable for stainless steel and carbon steel welding,
petrochemical industry reactor inner wall surfacing transition metal;
Or used in poor toughness of martensite, ferritic stainless steel welding.
Ripple fine
Acid type stainless steel hand electrode, jet arc,
the main component is low C-22%Cr-12%Ni, excellent cracking resistance
Good welding operation, stable arc, beautiful forming, delicate ripple, little splash, easy slag removal;
The coating has good fire resistance, good porosity resistance,
stable mechanical properties of molten metal, and high X-Ray pass rate.
Easy slagging
