Topic: E-Coat Finish
The parts that we are having the issues with are all from vendors. We have are own stamping dept. and this problem is not an issue with our in house parts.
Anyways, if you look at the parts before weld there is dirt on the parts(there is oil on the parts also) after welding the oil is baked off . The paint finish looks like weld splatter all over the back plate but it is not weld splatter, we know that whatever it is its not getting cleaned.
Q.A is saying that it is a Paint Shop problem and I do not believe it is. We paint over 100 parts and this issue is only with 4 or 5 parts and they are all vendor parts.I think whatever is on the oil is getting baked onto the part during weld. you can feel it on the part after weld but its not coming off during pretreatment. Can anyone help with this issue?
