![]() ![]() This will help to avoid cracking in the weld. Use hammer peening for residual stress relief after each run.Use very short runs of a maximum 30 mm length also called pilgrim welding, no preheat usually but if needed to remove moisture, preheat to a maximum of 110 Degree Celsius or 225 Degree Fahrenheit.These rods offer a dissimilar weld deposit with high ductility to withstand the high residual stresses arising in cast iron welding. For welding, I prefer to use the “cold method, or also called cold welding” ENiFe-CI SMAW coated stick welding rods.Clean the welding area & surrounding area from any paint, grease, or oil contamination.This will help to eliminate further propagation of the crack into the material. First of all, drill holes on both sides of the crack to arrest the crack.Click here to Get a Guide on How to Weld various materials Welding Repair of Cracked Gear Box Casing (Transmission Case) Steps to commence the Cast Iron Repair: ![]()
