Tigfil Cuni: Classification: Approvals

This document provides information on a solid filler rod for welding copper-nickel alloys. The rod is a copper-nickel type alloy containing 70-30% copper and nickel. It can be used to weld wrought and cast 70/30, 80/20, and 90/10 copper-nickel alloys without requiring preheating. The rod produces radiographic quality welds when used with a shielding gas of argon at a flow rate of 8-15 LPM in the DCEN position.
