Process

GAS MIG TIG A.S.

Applications

Copper coated solid wire suitable for single pass or multipass welding od non alloy steels, for C-Mn steels and for fine grain steels. The higher Si-Mn content gives a good bead appearance. It can be used for boilers fabrication, industrial machinery costruction, car production
