Dude, seam welding is usually done with one inch beads then a 1.5 inch gap, then a one inch bead. Most of that you've got there looks like tack welds which dont really offer the strength that you'd get from seam welds. Tack welds will just sheer off under load and crack in half, that can never happen with a 1 inch bead. I've seam welded a number of cars, we always do them like that.

Also, When seam welding them we usually brace the strut towers with cage tube to the lower chassis rail (by cutting a 1.5 inch be of tube, welding that up right to the rail and notching the one from the strut tower forward to that), and back to the firewall, using a 150mm square 3mm mild steel plate as a base for that tube and anywhere else a tube gets attached to the car.

We weld right the way around it the tube, and the plates. When you weld the plates to the car, strike your arc up on the plate, and move it to the surrounding shell then weld slightly out of the v, this way you melt the plate nicely at it's edge, but dont melt hole though the cars f/wall.

- arm length gloves are pretty cheap mate :P (lol I have so many burn marks now, some of them take months to heal properly)

meh, its a 82 corolla, it had about 6 spot welds and urethane holding it together before hand so anything is begonna an improvement. The welder was set to like 11 million so its all got good penetration, and as dan said the cage will be tied into the front struts, shell be right......hopefully

=)
