I haven't touched this tank in about 8 weeks but I had some time after work today and my welder was willing to stay and weld it up.
I tacked in the antislosh devise. My very first melting of aluminum
These are not my welds. My welder Shawn ran these beads on the inside of all the seams. The tank is made from one piece with a top added. That makes no welded seams along the bottom edge.
Ready for the top
