SUBMERGED ARC FLUX

摘要

A highly basic particle flux for submerged arc welding that produces less than 7 ml/100 gr of diffusible hydrogen in the weld metal, which flux comprises a carbon dioxide containing compound with an effective amount of heat releasable carbon dioxide in the range of 0.5-3.5% by weight of the flux over 10% by weight of a low melting point compound and a binder.
