Characteristics and Application
AWS A5.20 E70T-4 Flux Cored Arc Welding Wire is a self-shielded flux-cored wire, it is designed for on site general fabrication and structural work requiring, good slag release and friendly to manage variant weld joints by longer sticking out. The welding for heavy machinery, large construction components is appropriate, also stiffens in large building. It is suitable for flat, horizontal and downhill positions, also it can be applied to build up the worn parts.
