Butt welding is better - but more intimidating for those of us low on the learning curve!

Tack then spot and stitch, Use .023 wire at a lower power. Tough to do without warping for sure. The body shop that did my 1/4 patches has a new wire brazer. It melts brass at a low temp to help with the heat build up.
