Welding Arc Wire

H08A is a kind of carbon constructional Welding Arc Wire. Different welding fluxes can be selected for it to weld the workpiece, so that the performance of welded joints is different; and in general, for carbon steel having low obdurability on welded joints, fused fluxes are used for welding, and for some low alloy steel, sintered fluxes are used for welding.
Purpose: It is widely applied to welding of carbon steel (for example, Q195, Q215, etc.) and some low alloy steel (for example 09Mn2, 16MnCu, 16Mn and 15MnTi) in industries of boilers, ships, pressure containers, pipes, etc. The used fused fluxes: HJ431, HJ433, HJ434, etc. The used sintered fluxes: SJ301, SJ302, SJ501, SJ502, SJ503, SJ522, etc.
