Are we also doing Butt and welds?

TIL this is just Bob’s way of saying “Butt”, and not, as I had assumed, bob’s special way of poking the pig.

Are we evaluating the coupons (cutting in half) or sending to metallurgist

Metallurgist is only going to do what you ask. What do you want from such an evaluation?

My thoughts were to see if we could all try different, size wire, volts and wire speed and find that sweet spot that had a good balance between penetration, weld porosity and burn through on Toyota gauge sheet metal.

Maybe help that new guy looking for a starting point. Most of the details would work themselves out because too cold won’t have any or very little penetration leaving porosity that water will eventually work its way through and bubble the paint and that should be easy to spot on the back side of a coupon, burn through is just that and chasing a hole will look like what you would think when you flip the coupon over so really we want to weld the front and inspect the back. Note the machine settings and share them with front and back photos..
