Joining of cast irons and cast iron to steels of similar/ dissimilar thickness. Repair welding of high strength, heavy duty ductile irons involving massive sections and for joints under restraints.
Clean the weld area from grease & other contaminations. Preheat part up to 250⁰C, if necessary. Always use short & medium arcs while welding. Avoid the excessive heat locally, hence skip welding is highly recommended. Remove slag between passes. Allow cooling slowly. Peen lightly to remove stresses.
