Spot welds
Hi guys, I'm working on the body of the td5 and drilling out the spot welds. I'm just wondering how difficult is it to weld these back up? Would it be better to just pop rivet and seal them?

Once the material has been drilled out it obviously can’t be re-spot welded, so you’d be looking at having each spot puddle-welded with an AC/DC tig welder.

Definitely not impossible, just not that many people around who have the kit. It’s the route I would take - LSL on the Fylde Coast could do it but I’m not sure who else does TIG. To buy the kit would be about £1000 - I’m saving for one now.

The far easier alternative (and arguably stronger) is to use panel bond adhesive with or without rivets. As you suggest pop or (if you can be bothered) solid, countersunk, aircraft rivets.

Here’s a video.

I have £5k of AC/DC tig welder and the know how to use it properly but I don’t use it to fix new panels. If you are replacing with new panels then best way is to drill out all old spot welds, clean the flange up and use Soudal Carbond to bond the new panel. Countersunk rivets can be used where they are hidden by cappings to provide a mechanical fixing.

I use the tig for welding up corrosion holes (usually holes in rear tub side panel from lower stay) or welding up holes drilled for chequerplate.
