Solid Wire Rod BA-TIG 312 for TIG Welding
Classification:
EN ISO 14343-A: W 29 9
SFA 5.9 / AWS A5.9: ER312
Main Application
BA-TIG 312 is a solid wire rod for GTAW, suitable for welding or surfacing hardly weldable steels. Suitable to weld buffer layers of hard depositions. The excellent mechanical properties and the notch resistance make this wire of general use.
