Swampy442 Posted February 26, 2013 Share Posted February 26, 2013 Is there a regulation that says metalwork on cars has to be welded? Im getting a car that needs a bit of plating in the spare wheel well and the rearmost panel on the car, where the rear lights attach. I work in an aircraft structures bay and have access to all manner of sealants and bonding agents, could I simply bond a patch repair on?

Benjy Posted February 26, 2013 Share Posted February 26, 2013 Can't see it, can't fail it. If it's solid and covered in seam sealer, you have to assume it's welded. Although if it's structural, might just be worth welding it up. Where it was seam welded originally, it must be seam welded, spot welds can be spot welded but patches must be seam welded all the way around.

bignum Posted February 26, 2013 Share Posted February 26, 2013 If its not structural or sharp on the outside i`m pretty sure its ok anyway, so get the pop rivet gun out:d Quote Link to comment Share on other sites More sharing options...

Benjy Posted February 26, 2013 Share Posted February 26, 2013 Thinking about it, why's it failed on a hole in the boot floor? It's only a fail if it has a sharp edge or petrusion caused by corrosion or if it's within 30cm of a suspension/steering/seatbelt mount.

jonc Posted March 2, 2013 Share Posted March 2, 2013 Gas brazing, soldering, adhesive bonding, fibre reinforcement and body filler are bonding processes and are not regarded as strong enough for repairs to load bearing members although they are normally adequate for other repair work. It is accepted that it is sometimes difficult to identify the repair method after the repair has been covered in paint or underseal. If the method of repair is in doubt the tester should pass and advise. I have welded all my tin in the past and left it bare for the MOT tester to see then sealed and painted it afterwards. Saying that I have a mate who is a garage owner and an MOT tester and above is from the MOT guide lines. Quote Link to comment Share on other sites More sharing options...
