How are casting economics and welding related?
Cosmetic welding can repair a number of possible scenarios in the foundry -- chisel or blade marks from gate & riser removal, sand inclusion, or a miss-run. A simple cosmetic weld repair, followed by heat treatment and X-ray, fixes the casting.
Sounds straight-forward, yet sometimes engineers put a note on a drawing stating, "No weld repair." Perhaps they are referring to structural fixes, yet they are also excluding cosmetic repairs, which drives up the costs and delays timing.
Collaborate with the foundry, and reduce cost & timing with a disciplined approach to cosmetic weld repair, see our guidance here:
