Applications

For low temperature repairs on all types of cast iron where extremely soft, machinable weld deposits are required. Ideal for intricate or thin-wall gray iron castings. Excellent for repairs on cast iron gears, machine tools, heads, engine blocks, and pump housings. This is also an exceptional electrode for joining dissimilar metals such as Monel, copper, stainless, nickel, and steel.

Procedure

Clean and prepare weld zone in accordance with standard welding practice. Vee out cracks using Excelloy 56. Use skip welding technique on complicated castings. Limit bead length to 1-1/2” to minimize heat input. Maintain a maximum interpass temperature of 200 F. Chip slag between passes and peen weld with ball end of ball peen hammer.
