The Renault Welding Thread

[Steve Swan]

Not the easiest of first projects. Looking good though, I would do lots of very short runs moving back and forth along the job to stop heat build up, as the new bit gets more attached it works better as a heatsink which makes the chances of blowing through less. I'm impressed.

 

[DaveL485]

Why is MIG better than TIG on mild steel/car shell welding? I would have said the opposite.

 

[Steve Swan]

Not better,but cheaper and faster and easier to learn. Bodyshops don't fix cars for the love of it, they are trying to make money,also less fire risk.

Haven’t been on for a while, but I got myself a TIG mid last year, but haven’t had a great deal of time to use it. That said, it does come out every now and then. Recently I’ve had to do some repairs and I’ve been forced into using it. Like others have said, the panels on the 5 are pretty thin. Generally 0.6mm with some 0.9 for sandwich reinforcement plates.

What I’ve found with the thin stuff is you need to use filler rod/wire of the same or thinner thickness as the sheet you’re welding other wise the puddle cools too much so you have to put even more heat into it, which enivitably leads to a blow out.

mum trying to do as much as I can using coupons, but you can’t expect to be great overnight.

Thought I would post up a bit about my Tig Setup. I am making the chassis brackets for the Z bar on the Dauph rear suspension. I like the Tig for its versatility on small jobs
Pic 1 The Machine itself


Pic 2 the Reg, and I actually have a flowmeter, which was only because I found it unused and unloved at the back of a cupboard at our Welding contractors place, so decided to give it a new home



It has a Standard torch, but my personal favourite is my teeny torch, so much better for the awkward corners (do old cars have any other kind?)

Fabricating the Mounts on 1.5mm box on 50A



Then turn it up to 95A and weld in the mounting plate



I am definitely out of practice and a bit wobbly

Thanks for watching
Happy Motoring

I like TIG, whether it likes me it still debatable
But it's nice to play about with something new.
Seat base is done and in paint , when I'm feeling brave I'll move on to tank, see if I can get it fluid tight.

 

[DaveL485]

see if I can get it fluid tight.

I'd like to see pics of that.

I Prefer Tig, it's just neater. But as Steve says it can take a Lot longer. I spent 10 hours welding up a T45 Cage for Duncan Grier, where as Mig would've taken 3 hours or so.

You can do mig in short burst to keep the heat down on panels, unless you can get to either side of it then tig is better as it has an even heat distribution into both side of the weld which makes it easier to dress. The mig wire is hard which makes it less forgiving.

I'm just 5 linking an axle for a Turner.

Been on and off more than a whores drawers this week.

The only bit I tigged on this was the filler plug as an A35 axle doesn't have one and it'x got a midget lsd going in.

Finally it's together, just needs a coat of paint..

 

[Mark_L]

Got a coat of paint on it. I'd normally spray it but there's just no room in the workshop today.

 

[Mark_L]

Forgot it's a welding thread, no paint necessary.

Just Tigging up the Arms.

 

[DaveL485]

Yikes! You can make me one of those for the 21 when I explode the gearbox and fit a couple of Tesla motors at the back

EDIT you should put that in your new forum bit.

I'll put a bit more in there about this Car. Been a nightmare. Only came in for cage. Haven't stopped on it yet over 200 hours and counting!

He's not looking forward to the Bill....

@DaveL485 I don't think you would really like a Turner, a bit basic for your taste. There was a guy up in Scotland used to hillclimb and sprint one. I remember it getting damaged and being a nightmare to fix the front end cosmetically, as there was not another that could be measured for its curves and bumpy bits!!

This is the same Car Steve.

Well it's a small world! and definitely, when low volume old cars are concerned. @Mark_L have you got a workshop thread? lots of interesting things in your workshop and very nice work being carried out too.

Andy has just done me a page so I'll be putting a lot on there.

We do have an Austin healey 3000 in that is going electric but we may not be doing it now. Shame as it would be an interesting project.

 

[DaveL485]

Some nice thick stuff to weld today so cranked the amps up and...

 

[Steve Swan]

Thick metal and a Mig. What's not to like

 

[Turbell]

First TIG on heavy stuff, M10 nut on some 2mm plate for a temporary tank drain whilst I strip shite out of it using a variety of chemicals ....
Probs a bit heavy with amps, and I've only got 1mm rods ATM, but if it holds fluid it'll do.
Bestist ever toy ever ....
