Sheet metal forming

(OP)
I have been working with a German engineer who has referred to a quilting seam. Before I ask this gentleman a dumb question, could someone please take me to school on this term?

RE: Sheet metal forming

I've also heard the term used for a spot-welded liner, where the welds are placed along a dimple pattern on one sheet, leaving a gap between the two sheets, either as an insulation barrier or for fluid to flow.

RE: Sheet metal forming

I'd >>>guess<<< it may be a reference to the regularly spaced crossed creases applied to thin aluminum sheets to stiffen truck body skins, in the manner of the regular stitch lines used to hold batting inside quilts.  Not, technically, a seam at all.

Or, not.  Ask the guy.

RE: Sheet metal forming

I agree with mike's suggestion to ask. I just asked the two people on either side of me what a "welding seam" meant to them and got two different answers.
