Badly mig welded car/partsparts

[the snooper]

On my engine crane

a good portion of that weld looks unlikely to have penetrated into the box section properly

 

[pondy]

This isn't structural or safety I know but looks horrible. Our driver at work asked Me to look at his sons car he just brought as the exhaust was blowing. It has had to new flex sections put into the original exhaust and the welding was bad and was blowing. The engine is a v6, one side wasn't to bad getting off and welding was better than the other side so think it has been welded off the car, the other Side was a pig to remove so I think looking at the welding it was done on the car, acsess to joint is very poor. Spent tonight grinding it all out and welding it all up

I doubt any of the welds have

It looks like TVR chassis a friend of ours had

Luckily not on mine, but I've also seen some welding on TVR chassis that wasn't too clever - from the factory!

 

[arceyered]

The thing what gets me cheesed off is the person who did it knows the weld is poor quality, but still thinks it's acceptable.
Welding is like any other skill, just because you buy a welder does not mean you can weld and know the weld is correct and safe.
If you don't know what you are doing leave it alone and let a pro do it .

I went to a TVR specialist a few years back to collect an engine, asked to use their toilet and was told to go behind one of the sheds. Stored there was a Griffith chassis and I could see why they were peeing on it as the welding was awful.

I cringe every time I hear "It's OK, it isn't structural". ( Applied to vehicles )

How would you feel if when driving down the motorway 10kg's of exhaust "fell off" the car in front
and bounced up through your windscreen?


Wasn't a woman killed by some moron dropping a single brick from a bridge over the A12?
But it was OK. It wasn't a structural brick.



I make no apologies for this post.

I see this sort of bad weld quite often, I often keep some bits for my black museum, unfortunately having a welder don't mean you can weld !!!

 

[God mode restorations]

I think the n.h.r.a should permit stick welding on chassis fabrication

is shocking the amount of crap welding out there can't help noticing even when im stuck in traffic and lorrys go past im looking at welds lol. i went somewhere the start of the month for welding assesment when i was talking to instructor about vert up he said just do it downhill that was on 10mm plate so not surprised really if thats what people are getting taught

When I was at collage 20 years ago..we were taught both up and down on 5 mm plate..they then stuck ya work piece in a machine a bent it until it snapped. .it had to pass a certain point without snapping..on all three processes. .even to this day I sometimes struggle with stick v up and down depending .

One thing is for sure it's got very little to do with which welding process and everything to do with the guy holding the torch

tvr always had thier quality issues it's like the guys were doing bubble at break time

 

[rory1]

I get parts from a well known agricultural dump trailer manufacturer that are very often that bad that I grind and re weld then before fitting them .

 

[God mode restorations]

It's surprising to see just how many bad welded machines..motors..ect there is in the industry. .as said I am not a professional welder and you guys could run circles round me all day with a weld gun/torch..and to scary part is some of this kit tools ect we buy from shops..Internet. .

 

[Tiggy_dorset]

I cannot expect much from a cheapie exhaust, but......

If I recall, the bore should be something like 21mm, was 17mm at the smallest point due to the weld blocking it up. I dont recall asking for a restricted c90 exhaust when I ordered it.
A die grinder sorted it out though.

 

[trewjohn2001]

Here are a couple -car passed an MOT car I bought the car "restored" from an MG specialist.

I have some other amazing welds to the front chassis leg as well.
Must have been three or four people who just kept plating over a persistent rust hole with another "patch" - it looked like puff pastry.

 

[trewjohn2001]

Other side.... If you can't see the hole does that mean it isn't there?!

I didn't cut anything away from that patch - there was a larger plate covering the bigger hole I just levered it off with a screw driver.

Wish I had taken better photos.

I hate it when you read people stating that their welding "isn't pretty but is strong".

I hate it when you read people stating that their welding "isn't pretty but is strong".

Indeed, I have yet to see an ugly weld prove to be strong when needed!!

They miss out the rest of the quote, it's:

"My welding isn't pretty but is strong(er than the filler and fibreglass I was gonna bodge it with)"
