Casting Welding

Cosmetic weld repair or In-process weld rework of castings is a normal casting finishing operation where the casting surface imperfections in almost all alloy families and moulding processes can be mended. The weld rework is carried out on surface and near-surface discontinuities/blowholes.

If done correctly, the weld repaired castings would resemble their non-welded counterparts both structurally and functionally. Many customers usually misunderstand weld repair in steel castings. Some companies do not allow weld repair at all, and others place strict restrictions on where weld repair can take place on a part. With a clear understanding of the effects of weld repair on aesthetics and functionality, customers will benefit from repair procedures that would optimize the cost, production time and part quality.

It is important note that good weld repair does not reduce part quality…
