NCT fail due to spot welding instead of continuous welding

mathsman3.14 · 14-01-2021 7:20pm #1

Hi all just wanted to see what some people thought of with this.

So I failed the NCT last week due to corrosion just under the front middle of the car which is fair enough!
So brought it to my mechanic, who I’ve dealt with before, and he patched it up.
Brought it back to the test centre today and it failed again...tester actually brought me in under the car and showed me and said my mechanic should not have done spot wielding and it should be a continuous weld.

What do ye think of that? A mate of mine said he’s kind of 50/50 over my mechanic knowing better and the NCT dude being fussy Just thought I’d ask, but please be civil! Hope everyone is keeping safe

In what way would anyone thing spot welding is sufficient?

Without seeing the repair or anything i cant picture a repair scenario where a spot weld is ok if it's repairing an existing piece of metal.

"50/50 over my mechanic knowing better and the NCT dude being fussy" Smart friend.

Not wishing to hang your mechanic,he must have thought it was ok,but continuous weld is the the standard. Some of the testers would even look for an assessors report.Just reweld & go back - even if it is a pain.

Is that genuine or are you just being sarcastic cos I did ask people to be civil if offering their opinion?

Thanks for the reply...yeah he was a bit taken aback when I told him but said bring it back no problem and he’ll patch it up

That's rubbish.

The idea of failing your NCT for rust is because the metal work is compromised or weakened. A weld repair has to be done to try and restore the metal to something close to it's original.

I'd say you could pull that plate off with a screwdriver. It's doing nothing.

Thanks for the reply...I’m not great with this type of stuff so please bear with me if I’m not making any sense...just noticed you said there that you can’t imagine a scenario where a spot weld is acceptable on an existing piece of metal...what if it’s a new piece? Again really sorry if that make zero sense...I’m on a bit of learning curve

That looks like it was tacked up and he forgot to weld it.

It needs to be done properly. That “repair” would have very little structural strength.

Well to be slightly pedantic he's spot welded a new piece of metal to an old piece of metal. But really that's besides the point.

I'm not being alarmist and you probably don't need to fear for your safety but that repair is definitely not acceptable and if anything, a bit of a joke. As above, you'd say the fella forgot to finish the job he started but for the fact he's painted over it.

Hard to make out from the photo's but my gut is it's spot welded as access is limited to that area and someone was trying to avoid stripping the car to either remove the part from the car or to gain enough access to do a proper job.

I'm guessing the bottom part of the pic is the plastic sump panel & the repair is the inside of the bottom box on the rad panel. In fairness to him,the fabrication looks fairly good,pity he didn't finish the job

Yeah, good spot, I actually neglected to mention it was around that area with the radiator, sorry about that....as I said I’m not an expert on card and I didn’t want to come across as making zero sense describing where the repair was...someone else said the same to me too, guess it’s just annoying that he didn’t finish it with a view to being accepted by the NCT...he’s an Eastern European chap, guess he thought regular spot welding 4 inches apart would be okay ahaha

all that is really doing is covering the rust hole, it should have been welded all the way around to be satisfactory repair nct centers have really tightened up on this in the last 5 years. See attached picture not tidy but minimum expected by nct center.
