Usage:
when applied to various welding wires such as h08a,h08mna,h08mnmo and h10mnsi,it can weld low-carbon steel,low-alloy steel and pressure vessel steel.and it is fit for fast welding of thin steel sheet like gas steel tanks and membrane water-cooled wall in boiler factory.
Cautions:
1.the oil soil,moisture,iron rust and other foreign substances must be removed from the welding joint.
2.the welding flux must be baked under 300-350ºc for 2 hours before welding.
