AWS ER80S-G

Description and Applications

HT80S-G is a cut wire for gas tungsten arc welding (GTAW).  It is used for welding root pass of 600N/mm2 high tensile strength steels, such as pressure vessels, storage tanks and penstocks.

 
Guideline in Usage

Preheating at 50 150℃ is required when the base metal is thick and restraint is high.
