AWS ER307

Description and Applications

Stable arc, good fusion with parent metal, and beautiful bead appearance. Good weld ability, crack resistance and also easy hardening process and no magnetism. Suitable for the joint different materials such as high manganese case steel and carbon steel.

 

Guideline in Usage

When high X-ray quality is required, stable spray transfer mode should be maintained with low current and slow welding speed using a pulsed arc power source.
