Welding Rods for Pressure Vessels->All->TY·SJ501 |
| TY·SJ501 |
Description:
TY-SJ501 is a kind of aluminum-titanium-type sintered flux,B‖W=0.5-0.8,mesh 10-40(2.0-0.45mm),Either alternating or direct current can be used.It has hight rust resis-tance and the sag 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,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 300-350℃ for 2 hours before welding.
