Weld Mold® 700


A commercially pure nickel weld deposit is produced which is easily machined, drilled, tapped and filed.

Applications

Weld Mold 700 is preferred for welding thin sections of cast iron where high dilution occurs and maximum machinability is required as encountered on shy castings and machining errors. Weld Mold 700 is also excellent for building up on large castings.

Procedure

Prepare weld area by beveling and cleaning cracked edges to be joined. Use Polychamfer electrodes for all beveling applications. Preheat part to 500°F. Maintain interpass temperature (150°F). Use stringer bead or weaving technique. Peen to relieve stresses. Wrap with thermal blanket and allow casting to cool slowly to room temperature.
