I am rebuilding a bucket for a cat 318. I am going to add more metal when I change the bucket front (?). What should the metal part I cut look like? Tips?
This job is usually performed with kits made primarily from tough plate with good impact and wear resistance. I've carried out these jobs before on big ones in mines, we used to arc air gouge the old worn ones off and refit the new ones (hardox) was a good plate for it some hard face plates were also good if it's not too hard or it can't take the impact. Google digger bucket wear plate kits and that will give you some ideas of where and how to clad one.
With all good standard welding practices the material should be clean and bright before welding. Are you replacing old worn out plates on the bucket. What are you replacing them with. (Material) a lot of the plates we used were made from hard face welded plate. Usually a mild steel 8mm plate with 4-5mm clad layer which would be around 40HRC hardness so that it wears instead of fractures and we would simply weld the mild steel base to the bucket with a solid mig wire (sticks were not practical given the ones we did 4 guys could stand inside them).
Not too sure the welded seam visible in that photo will hold for long!!! Been mig welded on dip transfer?? Not Ideal in any fashion, especially without cleaning the side plates next to the seam first
