Detail

Gas-shielded Solid 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.

Submerged-arc Welding Wire

All kinds of submerged arc welding products have excellent welding and machinery performance. They can be used together with many kinds of welding flux and easy to deslagging. The electric arc is steady, welding line is formed well and the welding speed is fast. In the process of welding, no splashing and arc light simulations in the melting of welding wire. The welding line surface is bright and clean, the welding quality is guaranteed and it is easy to realize mechanization and automation welding. At the same time the adjusting range of this kind of products is wide and it can be welded in open-air sites with strong wind. So it widen the application scope of the welding
