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
