WELDABILITY STUDIES OF MODIFIED 70-30 CUNI ALLOYS

The addition of either iron, beryllium or chromium to 70 to 30 copper-nickel produces three high-strength modifications when properly heat treated. The weldability of these alloys has been investigated by use of simulated welding techniques, the Varestraint test, and fabrication of actual weldments. Tests of multipass welds showed no loss of yield strength in the chromium modified alloy. A smaller loss than that occurring in single pass welds was noted for the multipass welds in the iron-modified alloy. No susceptibility to stress corrosion cracking in sea-water was observed in the iron or chromium modifications in either the base metal or the simulated heat-affected zone.
