A VERSATILE TIG WIRE FOR WELDING OF SIMILAR COMPOSITION ALLOYS.
IDENTIFICATION
Getig 842, ERNiCrFe12
CLASSIFICATION
AWS/SFA 5.14 ER NiCrFe12
DESCRIPTION
Getig 842 is intended for welding similar composition alloys. The deposit tolerates high dilution levels and is very resistant to hot cracking. It is not susceptible to sigma phase embitterment or carbon migration and is therefore ideal for service at elevated temperatures. The weld metal passes X-ray quality
