So, we’ve talked about gaps a few times (here and here), and if you’re not sick of hearing about them, thanks for your patience. Yes, there are other weld tolerance concerns, so let’s talk about one of the other common tolerances that can wreak havoc on a qualified welding process.
Thickness. No, I’m not referring to anyone’s skull, rather the tolerance of the cross section of the material at the point of welding. Depending on the weld joint configuration (assume autogenous for today), there may be 2 or more tolerances to consider.
