Hey there everyone - I've been away from the PC for large spells since joining the forum, as I've been working my way through the work on my project car - but that's not why I'm here today...
A friend I spoke to over a rare pint last week took it on himself to go to a further friend of his and blag some exhaust tubing and other scrap metals for me to practice on, for which I am very grateful, both for the thought and the deed.
I was a bit puzzled though, when he brought it round and said that the supplier of the freebies had asked what I was doing ('fixing-up an old car and doing some exhaust modifications'), and sent the metal with the message 'he can have as much exhaust tubing as he wants, but he's wasting his time with MIG welding on exhausts'.
So what the heck does that mean?
I've already done some exhaust work, which entailed chopping the end off a part of the Saab, replacing the damaged bracket with one off a rusted but undamaged piece and butt-welding the original back together. There was splatter-aplenty (of course), but there was also a good strong join, with plenty of penetration / colour change and minimal intrusion into the inner part of the exhaust (the weld is within 10cm of the end of the tube, so you can see and feel the 'other' side of the weld quite easily). It's also gas-tight (well, water-tight, as I bunged-up one end, filled it with water and checked for leaks / seepage), and it's been happily in place on my daily-driver for a month now.
I can't think that the temperatures or vibration experienced by an exhaust would preclude MIG welds, so is this bloke trying to help, or just being a (insert suitably descriptive expletive of your own choosing, here)?
I'll still take his freebies off him , but it winds me up something rotten if he's just being ar*y for the sake of it.
