Few questions

Before that is it tig or mig ? Not sure, but I know little bit about this like letting it cool off and to tack a bar in place to reduce flex etc

1. We see this all the time on race cars to improve rigidity so has anyone done it? Any tips or tricks? Because I hear the chassis wi flex.

2. If we were to go to a professional to get it done what would the cost be? Say for just the front strut towers ?

3. There's a tig I've seen mentioned on an earlier post for about $560 would this be suitable.

4. If it is feasable and practical I may buy it and do my car just for fun to see what it's like, obviously you don't need much experience to spot weld inch on inch off. Would there be by probs other than flexing?

Depending on things I may be willing to help out fellow sau members but that depends on time taken to complete etc.

Let me know ta!

hi bud.....

have you ever welded before..?? tig and mig a toatally different....if you buy a tig buy a gas regulator consumeables such as tugnsten tips nozzles and diffusers.....oh and a bottle of inert gas...argon...migs need gas aswell...or you can you a flux cored wire (gasless) just so you know you can get flux cored wire thats requirs gas too.....

inch on inch off is stiching not spot welding...

what are you hopeing to acheive?

what sort of driving do you do is it even worth the time money effort???

I see, I guess I'll be stitching then ^_^ improve rigidity for track use and I have used a welder in high school some 6 years ago, but if it helps I know I will do a quick course on it, basically just put stitches all over like strut towers etc I'll post up a few photos when I get home but yeah the whole idea is for improved rigidity and less chassis flex and flatter cornering etc willing to spend 560 on a welder to do this

ah i see...maybe it would be money better spent on good suspension , better sway bars spring shocks......etc

myabe i dont know....:D good luck with it anyways mate..i got a mig welder new off ebay for 290 delivered it works a treat....running gassless....i think it was from Geoffs Tools online store (ebay)

;)

TIG will give u a nicer weld-presentation wise,& depending on the operator probably more penetration.

Mig is quick & easy but doesnt look as good as TIG.

& yes dont use gasless on your car it looks shitty no matter how good u r at welding.

shielded welding (gas) will alwyas give a nicer weld...and you can get a nice looking weld using gassless......dont know why everyone thinks gasless is so horrible

Hey mate tig is the go, and it will take alot more work than just the strut towers. I fyou really wont to gain something out of this you will want to weld almost every seam on the car in which case you will need to pull the windscreen out weld all the way down the join there the shotgun panels stich the underside of your car and so on, it's a big job if you want to do it propaly if your in melbourne outer east give me a pm and I'll come out and show you were you want to weld anyhow good luck....

Too bad I'm in sydney :P well I've got this rolling shell sitting in the back yard you see so I wanna slowly do all that prepare it for track fun... You think doing just the strut towers + the whole interior and boot will have any effect? Don't wanna start pulling windows out if I don't have to...

hmm just come across this thread and its exactly what i'm doing right now with my R31 skyline shell. TIG welding ALL (yes all) the seams and joins of the body. Though i'm only welding in the cabin area, as front and rear has strut braces going on. TIG is better than mig as it moulds the joins together rather than adding to them.

The only downside to welding most seams in your car, is you go through a lot of gas, and gas refills are around the $90-110 mark.

And yes, it is really easy to blow huge holes in the body if ya not careful.....practice on something first !!

I'll have to take pictures and post up my R31 body.

ok i could write a whole page of dos and donts but short answers r

1 done 8 full cars and bits on i dont know how many cars .best trick is prep clean the surfaces back to bare metal then clean some more

seam sealer between the pannels is your worst enemy

you will only get flex if u heat the area to much

2 just the towers u say, if u do all the stripping n some prep around 350 if they have to strip ,prep,weld,seal,paint,around 1300

3 i would not use a tig i would use a mig some reasons are speed mig is much faster, n trying to tig upside down under the car is not easy

and it is easier to get the mig into tight places

tig is good for small jobs un less u have a fark off watercooled tig

4 heaps of othe problems if the prep is bad, fires ,chocking on smoke clouds , burns from boiling seam sealer splashing back at u

good prep will make a big difference

heres a few pics

More cost effective to diy, how come yours are spaced apart more than what I've seen on some map cars? Any noticeable difference in feel of the car? Rigidity? Flex?

i usually go in between spot welds as it is already welded on that spot as the name sugests.

it does make a difference but u wont notice much if the rest of your set up is lacking

if u do go to the effort then another thing u can do is around the door jams with a spot welder

new spot welds in between the factory ones

Mmm now to hunt down a mig ^_^ thanks alot for the great input guys once the funds are back up I'll start posting up pics, but first I need to add a boost cooler to my daily

i just bought a new 3 phase mig and want to sell off my gas/gasless SIP Mig if your keen.

similar to this item - http://cgi.ebay.com.au/SIP-Mig-Welder_W0QQ...106122001r15622

i payed $575 retail for it

    • Yes, I know🙄 but the sequential is not in my budget... don't want to reduce power neither, so looks like I'm stuck in the rabbit hole🤣
    • You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.
    • Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?
    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
