Decorative/Brite Passivation-A

From Able Electropolishing Company, Inc.

The weldment is used in a food heating system for a
major fast food chain. The part is formed and welded. They require a
uniform and stain-free appearance. However, the welding creates discoloration
and contaminates the (HAZ) heat affected zone. The (HAZ)
is a source of a contaminated oxide from the heat generated by the
welding process. This created a serious finishing problem.
