Agglomerated Welding Flux TH-SJ501

Conforming to:GB /T5293 F4A0-H08A F5A2-H08MnA Equivalent to:AWS-A5.17 F6A0-EL12 F7A2-EM12K DIN BAR 188AC10KM

Description & Applications:

1.  Aluminum titanium acid sinter flux

2.  AC/DC,  the welding wire connect the anode  in the basis of  DC  welding

3.  Can welding low carbon structural steel and low alloy steel. Such as ships, boiler, pressure vessel

4.  Especially is suitable for high speed welding plate

5.  Especially it is insensitive to oil, rust, scale and dirt on the surface to be welded. Most being applied to double-side with single pass weld and fillet welds.

 Remark

 

1.    Before welding, fluxes should be baked for two hours at 300-350°C

2.    Removal of rust, oil, dirt, water, impurities, etc in welding-areas
