H08MnA (EM12) Submerged ARC welding products in drums have excellent welding and machinery performance and can be used with many kinds of welding flux. The electric arc is steady; welding speed is fast. There is no splashing and arc stimulation in the melting of the welding wire. the welding line surface is bright and clean, and the welding quality is guaranteed and it is prone to realize mechanization and automatic welding.
Thisi series of submerged arc welding products are widely used in shipbuilding industry, large steel structure, pressure vessels, bridges and so on. Some products with special marks have been used in welding of vessels in the nuclear power station.
