TIG Welding Learning Post
Turbo Mini Forums

First, got to say thanks to Andy Waller & mini13 for lending me their MIG & TIG welders. The MIG was to weld my mates car up, TIG on loan just so I can practice before I make some parts for the car.
The first attempt was an abortion (11.30pm last night, bored, pissed and using wrong tungsten) but with some advice from Joe today....the second attempt wasn't bad. After about 5 minutes of practicing..................




The Mitech machine is a cracking little TIG

Flash cunt....

Also WTF you talking about Willis?

that was 7 minites practice you fibber!

With MIG machines, can't beat Clarke ones for welding cars up. Not alot of cash either.
This is the one I did Andy's Miglia cage with, done us proud.

That's bloody good for a first attempt.

I'm assuming that's aluminium.

Saul Bellow - "A great deal of intelligence can be invested in ignorance when the need for illusion is deep."
Stephen Hawking - "The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge."

Yep....
To be perfectly honest, had the odd go before and I believe if you can gas weld, you can TIG.
Who wants to see the attempt last night while pissed using stainless rods?

just dont show my attempt from earlier LOL

Thats pretty camn good for Alu.

Anything Ive welded with Alu has been a fucking mess !!!

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Hands up....got admit bad mistakes.......



Moral of the story.....don't try and be clever when drunk & try TIG weld something!

Welding stainless needs backing gas unless it is fillet welds your doing. If your gonna weld something like a custom petrol tank you'll need to purge the vessel with argon. I could go on for pages and pages on this, I do it every day at work. I weld aerospace stuff.
Oh and that alumium run you've done looks quality.

Quite amazing what coded welders do. We hired one the other week to weld ally rads for tanks. Quality work, truely amazing.

Last night I was trying to weld ally with stainless rods.....hence drink & welding.

Ah ha, external corner, easy peasy, now try welding into an internal corner

Looks good :)

Try CO2 & Argon mix rather than just CO

As it happens, I have a Clarke 120E mig. Looks just like that one in the pic above, but I have to say it's a bit intermittent. Some days it welds really well and others all I can get it to do is make pidgeon shit.

Probably just my lack of welding skill/experience. That said, could be my power supply prob's to the garage.

You tiging looks good.

I shall have a crack at a T fillet tomorrow....if I don't post a pic, you know its shite!

I'm using BOC Argoshield. I am a fool and pay for the priviledge of storing their bottle for them

Joe noticed this afternoon the TIG had to be turned up alot higher than normal due to the length of cable going to my shed. Wouldn't of thought your MIG would pull as much current, I might be wrong though.

Here's something I do at work.

Could be power related. I've got a sparky coming round on Monday to sort out my breaker issues for the spot welder. I might just get him to put a breaker board out there and do it properly....

Flash git! Nice work.

What kind of set up do you need to do stuff that fine? do you need a high freqency set like 400 Hz rather than the normal 50 Hz stuff?

The set I use at work is a Miller351 syncrowave with a foot pedal. Yes it's a high frequency set, don't exactly know what Hz it is though. The thinnest gauge I've welded at work was a 0.21mm butt weld with this machine. The pedal is essential for fine work as it allows slope in and slope out on the amperage.

.21mm! Fucking hell! I'll get me coat!

I think the rear chassis i welded up on the mrs's cinc was thinner than that PMSL
