Ceramic flux for arc welding of low-carbon - and low-alloy steels

机译:低碳低合金钢电弧焊用陶瓷焊剂

摘要

A flux comprising carbonates of alkali and alkaline earth metals, fluorides of alkaline earth metals, wollastomite and deoxidants, contains hematite (2-4% by wt.), manganese ore (6-10% by wt.) and metallic nickel (3-5% by wt.) as oxidants. The flux is suitable for vertical welding with forced shaping, and increases the strength of the metal in welding seams at temps. below 0 degrees C.
