seam welding and rear suspension strengthening, What to do, What I did... Options

[Andyrew]

So my project for a stronger chassis has begun.

Heres were Im at right now. Took the suspension out today.

I'll go do some welding and prep tonight, hit the bed, see what you guys say, and do some more welding tomorrow.

Picture of some buckling of the suspension. Other side has a raised area, but is generally flat, this side has raised and concave area's. I'll be adding something here for strenthening, a tube? A flat piece of metal? A triangle?

When you guys refer to seam welding, I become rather confused.

When one "seam" welds sheet metal that was spot welded together, does one run a heavy weld at the break (bend) or does one simply weld a bead past the spot welds at the end of the bent "flange".

Also when 2 "flanges" meet (along the bottom or top) of the longs, how are these "seam" welded?

I am assuming that MIG welders are being used.

Typically, when I think of seam welding sheet metal boxes, I think of how the gas tanks were welded (continuous spot welding between two rollers).

I need some pics of the "seam" welding.

Thanks for some pictorial explanations.
