In Process Welding

In Process Welding

It is the intention of every foundry to produce “defect-free” castings. However, even with the closest control of foundry materials and processes, deficiencies sometimes occur, especially with large and/or complex castings.

These deficiencies include cosmetic defects or processing damage.

Welding on Aluminum

In order to keep part cost down, in-process welding becomes an economical means of rectifying castings with minor discrepancies.
**********************************
It has been demonstrated that in-process welding does not have significant adverse effect on the structural integrity of aluminum castings, as long as the welds are done correctly, properly heat treated, and inspected after welding.
