Building Up Worn Sections Joining Cast To Wrought
Joining Thick Parts to Thin Parts
Tensile Strength: up to 35,000 PSI (250 MPa)
Bonding Temperature: 427 deg C - 538 deg C
Casweld™ AL Aluminum Brazing Rod Melts @315 deg C [Aluminium melts at 660 deg C]
Clean the surface and preheat heavy sections. Heat the first 50 mm-75 mm of the rod and dip it into the jar of Casweld™ AL Flux. Adjust the torch to a neutral to slightly carburizing mixture face feed into the flame. Apply the alloy drop by drop, moving the torch constantly. Allow to cool and thoroughly remove all flux residues by scrubbing in warm water.
For thin flowing, adjust the torch to 3X carburizing and preheat to a higher temperature. Then touch the end of the rod to the work and continue heating, forcing the molten flux through the joint. Allow the rod to melt off and flow through the fluxed area. Keep the torch moving constantly.
