JQ-MG50-6N

AWS A5.18 ER70S-6
ISO 14341-A-G 42 4 C1 3Si1

Introduction：

JQ-MG50-6N is a solid welding wire without copper plating gas protection, which has excellent rust resistance, excellent welding manufacturability, smooth arc, low spatter level, good wire feeding and optimal bead appearance. The product is applicable for all-position welding and the deposited metal has good mechanical properties. No copper smoke is produced in the welding process, so it is an environment-friendly welding material.

Purpose：

The product is applicable for welding various carbon steel and low alloy steel with 500MPa tensile strength grade, commonly applied in the fields such as bridges, buildings, automobile manufacturing, mechanical structures, etc..
