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. |
