Hi David, yes microwave transformers were a good source of a core and the turns required were minimal as the primary was already wound.
TIG welded lams were a cheap production technique as the lams were all stacked in one direction, as they came from the box, without the bother of interleaving them.
The weld, which was on the outer corners only, did constitute a shorted turn; but it was in an area of low flux so the increase in losses was pretty small in practice.
Cheers, Ed
