has anyone tried welding a front pipe

[pablo0874]

has anyone ever tried welding a front pipe on a terrano 27tdi lwb,
i am now the proud owner of a arc welding set and some rods but must admit im terrified of trying so must practise first but with a bit of practise is it possible to weld a broken front pipe if anyone knows also while its in situ on the vehicle ,
i know you can get a replacement quite cheap on ebay but i need a repair till after xmas cash being tight an wot not ,welding hints and tips much appreciated for a beginner:thumb:thumb2

I think the stick welder will probably blow a hole right through it. A mig might do it but I've never heard of it being done.

Easy enough with a mig, pretty much impossible with arc.

Difficult to weld in situ, the weld spatter could cause other issues, what is the problem, a hole, crack, and where is it?
I would suggest taking it off to weld, BUT this will cause other problems sheared studs, etc, and you may as well replace then.

If you have never welded before, then expect big holes, I tried to weld a Mini Sub Frame years ago with a stick welder, by the time I was finished it was worse than when I started.
So it was a new sub frame, not too bad to fit yourself !

Practice on some scrap metal first or what you are working on willl be scrap.
If you pay someone with the appropriate skills then it may be cheaper to replace.

if your going to weld insitue put a patch on it and try to keep the stick more on the patch than the thin/rusty crap. also turn the juice dowm. i think it will go tits up if you have not welded before then you will have to find the money for a new one anyway...

find the money and save the stress for another job...

If its a split, get an old bean tin and wrap it round with some gun gum and sew it around with wire, or use Jubilee clips.

I would normally suggest a GTX tin, but since they are all plastic now..:nenau

stick welding i thought was for thick metal work mig is much better for thin metal sheets you find on cars weather it is body work or exhaust hope this helps

That probably explains it, when I used stick, the work looked like a porcupine, with all the welding rods welded to the work... / / / / /:lol:lol

You will not weld any exhaust pipe with a stick welder. Its tricky enough with a MIG !

i have welded up the exhaust on my disco once with a stick welder took it off cleaned it up and used small rods 1.5mm i think with the welder turned down as low as it would go but enough to get a good weld with like spot welding ie do a spot miss a spot and go round until its a full weld
dont try a do a continouse weld as you will just blow holes in it
a practice would be best:thumbs
a mig would be better i only used stick as i had run out of wire
cheers Andy

It's almost impossible to weld thin metal with a ordinary welder the materiel just disappears,

I had my front pipe repaired in france when it broke away at the connector to the turbo,

but this was brazed not welded. I have just had a patch welded over a hole in my rear pipe

but this was done with a mig machine. regards bri

thanks for all the advice i think everyone has answered my question and the welder will stay in its box probablly put back on ebay ,
i will give the tin can wrap a go its only temporary till i get the cash for a new down pipe i know there not that pricey ,
it is just bloody annoying driving along sounding like a tractor or a boy racer in a vauxhall corsa lol.
I will go with the temporary bandagey can repair and concentrate on solvingf the first issue i had with the rev counter which i posted in electrics section which many of you kindly pointed me in the right direction .
I just havent got around to the actual finding the sensor or wiring due too the lovely weather here on the north wales coast .
think i will brave it tommorow though before anything else crops up in the form of electrics it seems one thing after another very temperemental my nissan ,
summed up in the last line of wildbris post a wise man learns by others mistakes thats why he uses this site many thanks good people

Years ago, you could buy an "Exhaust bandage", it was like a bandage, you wet it in water, then wrap it around the split and smooth it over by hand , then warm run the engine without revving until the bandage hardened.

Not sure if you can get them, but if ok would even pass an MOT then !!!

I use Gas for exhausts, can put the metal just where I want it no problems, Mig for body metal and 2 to 5 mm rods for heavier stuff, Rick

hi mate , disconect the battery, first you need to sand the steel down to bare metal, then get a piece of exhaust around the same diameter,clean it cut it length ways .and put it over the top put a jubilee clip to hold it, then tack it on, ( practice on the spare piece first to get the setting right, , when you weld it, do it in short spurts or you will blow a hole in it,

good luck hope this helps

i remember putting a baked bean can around my motorbike exhaust . held on with jubilee clips ( was a long long time ago )

 

[briggie]
