submerged arc welding fluxes, .agglomerated fluxes, SAW Fluxes

Description

Description:
      SJ**2 is a kind of silicon-calcium-type medium sintered flux,B∥W=1.**1.1,mesh ****0(2.**0.*5mm).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 (H*8A or H*8MnA),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 ******0℃ for 2 hours before welding.
