AWS ER70S-G

Description and Applications

HT70S-G is a cut wire for gas tungsten arc welding (GTAW). It is used for welding mild steels and 500N/mm2 high tensile strength steels. Deposited metal contained 0.15 0.20%Ti shows excellent toughness.  It is suitable for welding root pass of steel structures, such as pipes, pressure vessel, machinery, and vehicles.
