Stop in for a cup of coffee

Almost 1/2 way around patching inner wheel tub. Opted for small sections and weld them in.
Slow process,but progress nobetheless. Hoping to get right side done, then on to other side.
For plug weld, i drill a 5/16” hole almost through both layers and it makes like a bowl. Seem to work very well, and a few are almost perfect, no grinding.
