MIG wire, welding wire, cooper free welding wire
This welding wire has excellent welding performance and welds with CO₂or complex gas protection gas. The welding wire is steady to transfer wire, the welding line is formed beautifully, the welding slag is thin and easy to fall and the welding line has good breaking strength and anti-low temperature impact resistant performance. It is applied for welding of all-position and bigger electric current range.
This kind of products are widely used for welding of steel structure in mineral machines, engineer machines, ships, bridges, pressure vessels, building constructions; welding of other 500MPa level carbon steel and low alloy steel; high-speed welding of light gauge plate and pipe line steel.
