| TY·SJ302 |
Description:
TY-SJ302 is a kind of silicon-calcium-type medium sintered flux,B∥W=1.0-1.1,mesh 10-40(2.0-0.45mm).Either alternating or direct current can be used.The welding bead shapes well and the welding slag is "shor slag". And the welding seam has fine tough-ness and moisture and crack resistance.
Usage:
When applied to welding wires (H08A or H08MnA),it can weld boilers,pipeline steel and common steel.
Cautions:
1.The oil soil,moisture,iron rust and other foreign substances must be removed from the welding joint.
3.The welding flux must be baked under 300-350℃ for 2 hours before welding.
