LT*ER70S-G 0.8/1.0/1.2/1.6MM SOLID WELDING WIRE
Conform to Standard :
GB/T 8110 ER50-G
ISO 14341-B-GS11
AWS ER70S-G
JIS YGW11
Specification:The welding current has been strengthened to a great extent and the welding efficiency has been improved. Because the grains of the deposited metal have been refined, both the tensile strength and the yield strength will be improved too.
Purpose:
1.Used for welding all kinds of 500MPa structural steel parts.
2.It can be applied for high-speed welding steel plate of 500MPa
