will tig do the job?
hello
so now the time has came to buy a welder and start welding the frame. i was being offered a tig by a friend(150 amps) . so my question is
-how difficult is it to weld with tig than with mig, haven't done any of them though have done stick welding.
-which will give better results.
-what are the disadvantages of tig?

Biggest drawback of TIG is the welding speed is much slower.
Do a search this has been asked many times with the pro's and con's being discussed at length.
IMHO MIG is the better choice, I have both.

I welded up my chassis with a TIG. Its great but it is slower and is more difficult to reach corners etc. However its a million times tidier and you
can use the same set to to stainless manifolds and fine work.
Also when working with TIG, if one hand is holding your torch, the other some filler rod, whats holding the item? I ended up having to buy a few
clamps to hold items in the correct place while welding.

TIG joints have to be totally clean before welding..
MIG... you can get away with quite a bit of dirt etc..
For a chassis I would use a MIG every time... its easier to get a consistant weld on every joint!

tig make the welds nicer, but are harder to get right, so mig is the best option unless you are a trained person in tig.
i would go mig if it is just mild steel.
if you look at madtag on here photo archive he has a stainless steel chassis which is tig welded and that looks awesome.

If I recall correctly, Caterham chassis are made by Arch Motors in Huntingdon and they are bronze welded.

Thank you for that. I stand corrected.
I'm sure this is progress and the way forward but sad that Arch and their traditional methods have been side-lined. I suppose the same could
happen to Morgan, or has it already?

imho tig is better every time, once you have got it right. its worth the time and effort to learn tig as its much more veratile and produces cleaner
welds. the downside is the gas is more expensive and a weld takes much longer to do.
the major advantage is you can weld really thin sheet metal better, even weld coke cans
