im putting a new bottom in a cat 972g loader bucket. welds seem to cracking on cutting edge side of plate. i read on this site about pre and post heat. how hot? customer supplied plate
Reply:Is the bottom plate is AR400? How thick is it? This will affect how much pre-heat and interpass temperature that needs to be maintained.What filler metal and process are you using to weld the plate?Benson's Mobile Welding - Dayton, OH metro area - AWS Certified Welding Inspector
