Not Pretty,but Hopefully Effective

What gas where you using? For seriously looks like weren't using any

I was thinking that !

Fair play for posting that on a forum ! and for having a go yourself as you HAVE to learn somehow

[Error404]

Thats what i was gonna say - either no gas and/or far too much wire speed on the MIG?

trouble is it looks like you got **** all penetration and just splatter so it really won't work - if you linished it back to smooth I bet there are thousands of holes and pits in the joints - fair play for having a go but TBH I don't think it'll last long dude

Give it a clean up and get it fitted.

I've got a lot of time for people who are willing to have a crack, even if they make a hash of it.

Fair play

hahahaha But you got a point, it's performance that counts!

Yes it is true, however the downpipe will have more holes in it that a hollyoaks story line I fear.

Just out of interest once this is done does it have to be back purged (iirc with argon or something)

I'm learning as well

[rj scotty]

Is it stainless or mild ?

You back purge to prevent weld oxidation on a pipe as the shielding gas is outside the pipe not inside, so the inside weld has oxidised and is roughly 30% weaker and can form minute cracks. and will cause premature failure.(think cheap chinese ebay specials)

Fook me thats some scary looking welding, i'm assuming it's stainless pipe? what wire did you use for the MIG and was the gas on or was it with a gasless welder? one of the pics looks like there is an arc welder electrode holder behind??
I would clean those "welds" up and see what the penetration is like and fill in all the pinholes before even attempting to fit it to the car,
Good on you for having a go and showing it on here
Close but no cigar this time tho:mischeif:

[Acidburn]

@ dubmeister - thanks for that, thought that it was something like that learnt something worthwhile in 2009

304 stainless steel mate.

Unfortunatley, function over fashion does not cut it when it comes to welding. 99% of the time, if it looks s**t, it is s**t. That 'weld' will be full of porosity and will almost certainly have zero penetration, and will therefore be very weak, and it looks f**king awful!
If I were you I'd buy another piece of tube and cut it into small pieces and practice welding them back together. I can MIG weld but I've never TIG welded before but I wanted to make my own exhaust, so that what I did. It's taken me hours of practice but this is where I'm at:-



I'm still not happy with it so I'll practice some more until I am. Do some reading on here to

There is a forum with loads of knowledgable people who will help you out. Seriousley, throw the down pipe in the bin and start again.

I hate to say it mate but
