WELDED BLANK ASSEMBLY AND METHOD.

摘要

A welded blank assembly (200) includes a capping material (210) in a weld region (220) of the assembly. The capping material can help protect a weld joint (208) joining first and second sheet metal pieces (12, 112) together. At least one of the sheet metal pieces has a coating material layer (18) that is removed prior to forming the weld joint so that the coating material does not contaminate the weld joint. The removed coating material can be collected before the weld joint is formed and reapplied as part of the capping material after the weld joint is formed, effectively changing the coating material from a potential weld contaminant to a weld joint protectant. The capping material may also include additional material from a source other than the coating material layer.
