Cement mill Cracks in the mill ends . This case of damage was investigated to decide if repairwelding is a sufficient solution when the ends of a cement mill start to crack and are in danger of breaking. To ensure that the damage is repaired reliably, the cause of the damage must be investigated and weld seams examined carefully.How To Weld Repair A Gear Box Casting? Material Welding,Steps to commence the Cast Iron Repair: First of all, drill holes on both sides of the crack to arrest the crack. This will help to eliminate further propagation of the crack into the material. Clean the welding area & surrounding area from any paint, grease, or oil contamination. For welding, I prefer to use the “cold method, or also calledGear Repair PPGWorks,Gear Repair and Rebuilding & Manufacturing all Types of Gears Our unique style of gear repair and rebuilding, reconditioning and recutting on all types of Gears.
