Does Spot Weld on SECC comply to RoHS? How this can be explained?

June 9, 2009

I came through a situation where my customer requested there should be no spot welding to take place on their products. It seems ,due to RoHS compliance.
It happened that, we tend to rework those in-process rejected part by performing spot welding.How this can be explained? Is that , the content of the metal sheet (SECC) generates anything, upon heated up by the current flow? Please advice...anyone?

As someone who used to work in the metal fabrication industry, I do not understand what spot welding has to do with RoHS. Spot welding is essentially using electric resistance to fuse to metals (generally steel sheet) together. In some variations a filler metal may be introduced but again this is generally steel. Therefore,I do not see how RoHS could relate to this operation.

I'm with Gene on this one. I have spent years in the UK dealing with RoHS compliance issues and can think of only one instance where welding was an issue. We had one instance where a weld-through primer was used that was chromated. This was replaced and the issue went away. If you are not using any such animal then I can't see where you would have an issue.
