brasing is illegal on cars now apparently?

[Adam Brown]

Just taken my car for a mot and the tester said that having repair patches braised on is now illegal and can't pass my car because of it? So he is saying all the work I've done repairing my car will need to be cut away and welded in ? I'm pritty sure cars have Have been braised and nothings been said in the test and all of a sudden the law has changed.???? Is he chatting shit or is it now illegal ? As Apple the work I've done time I've spent ect has now gone to waste

[alladdin]

Brazing was outlawed years ago but modern insurance repairs are mig brazed so I don't know how it ties in

[Graham]

as above, ive been in the motor trade for over 30 years, Brazing has never been allowed in all that time.

whole panel replacement may be another matter, but MOT rules state repairs must be a continuous weld

[Adam Brown]

So are you allowed to braze New pannels on but not repair patches ?

[Adam Brown]

As I'm trying to get the mk5 fiesta back on the road it's a bag of shit but by no means rotten it's a small area where the sill had been crushed with the Jack and I brazed a new L plate on over the sill where it's been crushed and he failed it because I used braze. Well I can't do anything about the law but is there a reason why it's band ? It's just as strong if not stronger (when it's done right) never knew it was a problem ��

[Adam Brown]

What if a car like an old Ford escort from the 70s had braze on ? I know it was legal then so if the work was done before it was band could you blag it through mot ?

[Graham]

its still a fail, your only hope is if it cant be seen due to paint, underseal, seam sealer etc etc.

the problem with braze is one of surface area, how do you know if the braze only just joins the edges together which is weak or has flowed between the sections to create a large bonded area which is strong

[Fridgeman]

just asking here Graham so something like a 100k works escort of which there are a few with fully seem brazed shells are they in trouble ?

[Graham]

you need to diferenciate between brazing, and repair patches covering rusty holes two totally different things, one is ok and the other not.

a lotus elise chassis is glued together and obviously passes an mot, but that doesnt mean you can glue patches on your escort and pass an mot

lets face it a 100K escort isnt going to turn up at an mot station looking like its been patched up, and its highly unlikely to have any bare metail with bits of braze showing

The easiest way Adam is to cut the plates that are brazed onto your Fiesta sills out with a small angle grinder with a super thin disc in. Then get someone to MIG weld some new plates on, welding all round the patch. As for the Escort that could be another problem, if you have done a lot of brazing then your only option might be to disguise it well with paint and Wax Oil if it's underneath the car.

In period in the 70's Boreham and Safety Devices seam brazed all their shells which were mostly new, they said it always gave the shells a degree of flex. If you look at a modern day prepared shell from a company like Historic Rallysport then you won't see a bit of brass, just very good quality MIG and possibly TIG welding.

I think the point about factory shells is a bit bogus as they were 'off the line' shells, so spot welded already! The stitch brazing was just additional to reinforce the welded structure. As Graham says brazing if done properly is as strong as welding and in some cases - chrome moly tube for example - better as the lower heat doesn't harden the steel. Many cycle, motorcycle and kart frames are still brazed and their integrity is not in question. Word of warning, welding over braze is a nightmare - the two don't mix so its either a lot of grinding to re-weld or disguise and different MOT place!

[Fridgeman]

wasn't a trick question just how things were interpreted by Mr MOT man if he saw some exposed braze. we know brazing did the job for many years ok just sold a mint one.

Right let me make it clear
most cars have either brazed, bolted ,welded , masticed panels, the only problem for mot is
the chassis and seals cant be brazed ,if a car has chassis rails you can braze the seals on if it has no chassis rail and the seal and floor are the main struture of the car it needs to be weld ,any chassis section on the car cant be brazed it need to be welded, alot of mot stations dont know that so when they see brazing they fail it .
Also it need to be welded if its within 30cm off any steering or brake suspension mounting point other than that you can braze the shit out of it .you can also under seal and body guard it, us mot testers are not aloud to scrap it of all we can do is pass and advise
