Submerged Arc Welding Wires By Laiwu Jincai Welding Materials Co., Ltd.

H08MnA is a kind of Submerged Arc Welding Wires It has excellent welding process performance, the electric arc combustion is stable, the weld seam is handsome, the slag is easily removed, and the welding methods and the process requirements such as big line energy multi-layer multi-pass, double-sided single-pass and high-speed welding are met.
Purpose: It is widely applied to welding of carbon steel (for example, Q195, Q215, Q235, etc.) and low-strength alloy steel (for example, 16MnCu, 16Mn, etc.) in boilers, pressure containers, bridges, ships, etc. The used welding fluxes: Fused fluxes: HJ230, HJ330, HJ433, HJ434, etc.; and the sintered fluxes: SJ101, SJ107, SJ201, SJ301, SJ302, SJ501, SJ503, etc.
