Weld Mold® 4046


Weld Mold 4046 is a nickel-aluminum bronze alloy.

Applications

Weld Mold 4046 is used for the welding of cast and wrought nickel-aluminum bronze ship fittings, ship propellers and power plant components such as screens, valves, pump columns and piping systems. Also used for welding Nibral boat propellers.

Procedure

For best results, clean area of all matter and debris. Make sure the joint area is dry, as moisture will have a tendency to cause porosity. In overlaying iron base metals, apply the first layer at the lowest amperage possible and weave to keep the base metal dilution to a minimum. Apply three passes where possible, keeping in mind that all slag must be thoroughly removed between beads. A 300ยบ F preheat and interpass temperature is recommended.
