When welding frames I always clamp stands well past the area I'm working to pull a strings tight, then notch a sticks for gauge. Short weld, skip weld another place, other rail whatever, then come back, repeat...
Okay, read up a little on skip welding as they call it, still stitch welding, but its actually back welding for heat purposes , but then coming back , and actually seam welding or a complete weld, only for the purpose of heat distortion.
We did a lot of pre bow. Pre bow on base plates that required a seam weld was much easier to just put in an established pre bow , let the heat pull it back straight, instead of having to mess with a bunch of stopping ,and starting welds. Of course in these frame applications ,thats not possible .
I'm sure if doing enough to know how much the welding would distort thing would be good. But I was working in a gravel parking lot, with portable tools. Need to cut the rail at angle? Clamp guide block to rail, mount a cut-off wheel on the skill saw. Use grinder to bevel the parts that hard to bevel once parts are stuck together. Use the easy to grind corner to check alignment, weld the parts that where ground, let cool, grind some more, repeat...
