hello all.

I have a land rover discovery 2 2001 model and i have noticed that the chassis is bad in a few places and is rusting through mainly at the rear where it bends up at the fuel tank.

I am thinking of getting a mig and welding it up and wondered if any one has expierance in this field as i am thinking of getting a 90 or 100 amp plus hobby welder like a clarke or sip or something and wondered if this welder would be adequate.

Also what gauge of steel is best for welding the chassis as i will need a welder suitable for this.

And any welding or fabricating tips would be usefull.I plan to grind parts back to metal weld it rust treat it with jenolite or something and then hammerite it or something.
Any advice would be greatly apprieciated
many thanks
guy
 
You will want about 180amp minimum for good chassis welds, 2.5mm steel will do, not sure what the actual thickness of a D2 chassis is although I'm sure someone will be along to tell us soon...
 
Standard chassis is 2-3 mm just make sure what your welding is clean and get plenty of practice in and you can't go far wrong
 
130 will **** through chassis, I used a 150 last year to do my chassis rebuild and it was fine on medium setting and phase one with a mid wire feed, set up the 130 to about the same and it should be fine.

I've got big 190 now with full gas set up and that eats through 5mm with ease, 3mm plate is good for repairs get some from a scrappy and it'll be cheap.

Also a 4" grinder with a grinding and a flap disk is a new welders best friend!

Old welders best friend too ;) although I rawly use grinding disks not just flap disks and slitting disks :)

Although I've got a 400 amp old Oxford beast if a welder so I can't really give advice on settings :p

I use a 415 butters if working at uni and that things awesome :D plus its already set up so I don't need to drag mine out of the shed and set up the gas evey day

True, theres welding and theres welding. You need 180amps as something the size of a chassis is a good heat sink and secondly welding duty cycle comes into play making your 180amp drop off to 140amp very quickly, especially with a diy machine
