Welding

Recommended Posts

 Turn every dial up to 11 to begin with. If you blow holes through everything, turn down to 10.

While I agree on near everything you said , you don't move backwards with a mig you move forwards , as you get better penatration and you also get better shielding from the gas 

You can go either way but, for King, being new to it, he'll find it easier to get a decent result  by drawing his welds back.

 

This video gives a pretty good explanation.

Takes years to learn to weld properly? How fcuking much welding do you actually need doing? Pay somebody to do it properly. Especially on the 4x4 if you taking kids in it,  I thought about learning gor all the gear an more in workshop  at work but what fcuk is point, pay the welder and enjoy doing sumat else 😁 

I've bought a jimny and the main rust problems are the jack storage area commom fault.and under the rear wheel area at the back

The wheel area was the size of your finger nail on each arch.

He quoted me £500 for the work.

I'm not paying that mate.

I've allways been under the impression of.if someone else can do it I can also with practice.

And I disagree that it takes years mate.

I've removed the rear seats and am planning on boarding it out.

It will never have rear seats again

So just want to weld it to the best of my ability and pass the mot.

I can do most things on a car.

Even change an engine or clutch etc. 

Everyone has got 2 arms mate and me and you have aswell..

I try and avoid cars but... Clean metal as much as possible, don't weld too cold practice on thin sheet, probably easier to blip the weld as opposed to attempting long runs, be aware of fire at all times. Gas should be around 12lpm easier with a flow meter on gauge, if it gets to hot let it cool right down before going again else you'll have to keep adjusting amps, a grinder with one mil slitting discs and a sanding flapper disc will be your friend, atb Joe

Some people spend years welding and never learn to do it properly 😂.. 

 

I did my ASME9 40+ years ago, I never mastered MIG and I've used some good profesional machines, I suck at it 😂 will use gas, MMA or TIG over MIG any day 🤣

I'd probably avoid it as if you over apply or it gets in joint you'll have porosity. You can get tip dip for nozzle but I'd probably leave everything clean, sometimes a tip will last month's sometimes you get burn back and it's over before you begin lol

I try to avoid buying 4x4s that need welding doing they have a habit of making you chase your tail 😂

Better off paying a little extra for something solid saves a lot of time and heartache.

Welding motor vehicles is a dirty time consuming horrible job in particular 4x4 chassis.

I've only ever used it in the nozzle to avoid spatter build up anyway, never been told to apply to a work piece, tip dip sounds good 👍

Trouble with any car welding is trying to get a comfortable position, half the time your on your back in tight spaces, jig welding on a table is a whole better scenario 🙃

That's for sure Gav. I would sooner re chassis or put a new half chassis on a 4x4 these days as patch them up every time the mot is due.

Yea I've got some cutting disc and the flapper discs.but the flapper discs are a little to big. And have to take the guard of the angle grinder to use them.

Some good info though mate cheers 👍

gripfill and primer......never fails.

Within 30cm of a body mount it has to be solid.so little holes in that area are a fail mate.

I've allways fancied being able to weld so now I'm finally giving it a go.

Eventually I want to extend a car trailer upwards into a box trailer.with angle etc.

As the price between the 2 is crazy.
