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. |
