Weld Mold® 672-C
Weld Mold 672 is a lower carbon and silicon version of our 673. This nickel base chrome-moly alloy is used for joining materials of like chemistries. More crack resistant than our 673.
Applications
Used as an overlay to resist corrosion on parts subject to oxidizing and reducing atmospheres and liquids at temperatures up to 2,000°F. Also used for the fabrication of similar nickel based alloys and some stainless alloys, including Joining ®Hastelloy C and C-276 to themselves.
Procedure
Use DC reverse polarity. Maintain a short arc and use either stringer beads or weave up to a maximum of 2 ½ times the electrode diameter. Pre-heat according to base metal.
SMAW - DC+
GMAW - DC+, 100% Ar or (spray) 75% Ar 25% CO2
GTAW - DC- 100% Ar
