Excel Cast 242

EXCEL CAST 242

TYPICAL APPLICATION

Low heat input electrode for surfacing & repair welds on all weldable cast iron & joining cast iron to steels. Applications include high strength joining applications on engine blocks, machine frames, wheels, pulleys, pump bodies.

PRODUCT FEATURES

  1. Excellent blend of tensile strength & ductility.
  2. Fe-Ni type deposit.
  3. High deposition efficiency.
  4. Maximum resistance to cracking.
  5. Machinable deposit with HSS tool.

RECOMMENDATIONS

For grey cast iron & for joining it to other metals. For applications where maximum machinability required. An all position electrode enabling maintenance work to be done in position. “Frigid Arc” coating controls penetration & prevents excessive base metal dilution.

PROCEDURE

V out cracks with Excel Gouge. Use AC or DC negative. Clean weld area. Preheat to 100°C to 150°C where maximum machinability is required. Maintain a close to medium arc at maximum possible amperage. Deposit short stringer beads 25 to 75 mm in length. Back whip each crater. Peen lightly to remove stresses. Chip slag between passes.
