Product Description
This is a kind of agglomerated flux for welding ordinary carbon and low-alloy steel such as boiler, shipbody, pressure vessels etc..
Product Feature
- Agglomerated acid flux
- Flux type: Aluminum-Rutile
- Basicity index: 0.5-0.8
- Grain size:2.0-0.28mm(10-60meshes)
Product Specification
- Provides very good weld bead appearance and excellent slag removal even with narrow groove and fillet welds. - High resistance to cracking and porosity. - Especially it is insensitive to oil, rust, scale and dirt on the surface to be welded. - As the consumption of the flux is very low,it is very economical
Application
- For welding of ordinary carbon manganese, low alloy structure and boiler quality steel in combination with appropriate SAW wire (such as EL8,EM12. EM12K).
- The flux suitable for high speed welding.
- 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℃.
2. Removal of rust, oil, dirt, water, impurities, etc in welding-areas.
