Welding panels for MOT

[hagarg]

Have you to seam weld all panels after removing rusted sections even when not structual ie side panels underneath

[Gromit]

If the panel was originally spot-welded on then I normally plug weld the panels back on, some MOT stations though (the funny ones) insist on seam welds for all panels, even if the originals were spot welded and non structural.

I usually weld all the way around purely because I can

Just follow what was there in the first place

If you're any good the tester will not be able to see the repair I did that once on a brand new escort for a T.U.V. repair in germany, the examiner said "Vo ist die repaire" a real highlight in an otherwise boring life

Spot welds can perform better in a crash situation that seam welded joints. The energy to begin the tear being higher than to spread it. For a row of spot welds to fail each weld must be detatched seperatly so increasing the energy absorbing potential. Once a seam wels has begun to split it is a lot easier to cause the split to run.
Whatever you decide, make a sound job of it then apply a good covering of filler/underseal so there are no arguements with snotty MOT testers.
