SJ501 is a kind of aluminum-titanium –type sintered flux,B//W=0.5-0.8, mesh 10-40(2.0-0.45mm).Either alternation or dircet current can be used.It has high rust resistance and the slag is easy to drop after welding.The welding bead is smooth and the welding technology has good performance.

Usage

When applied to various welding wires such as H08A,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 300-350 for 2hours.
