No actually spot welding IS what I was asking about
Seam welding is too much money and the car needs to be pretty much a rolling shell
Spot welding and chassis rail filling... any benefits?

Spot welding the chassis = seam welding the chassis = seem stitching the chassis, all the same thing, all done along the seams of the chassis, all same effect.
if u ask for your chassis to be spot welded, they spot weld along the chassis seams = seam welding, they dont just do spot welds in random places.
Im certain iv heard people & magazines refer to it as "spot welding the chassis" plenty of times.
You can not be serious that only occured to you now? :confused:Quote:

Yeah seam welding isn't worth it due to taking it to a rolling shell
But spot welding doesn't require the car to be a rolling shell?
And that's what I was talking about, at $55 an hour, even if it take 10 hours (car would be dropped off with no interior at all) it would only be a $550 exercise
hmmm i must be an idiot, can someone inform me what the differances are between spot welding and seem welding. Arnt they the EXACT same thing. If the person doing ur spot welding dosnt plan on doing it along the chassis seams, where the hell are they planning to do it???
Once again please correct me if im wrong, im here to learn, but seem welding involves spot welding or stitch welding (solid welds can weeken the chassis iv heard) along the chassis seams correct. Spot welds in other places are completly usless to my knowlege.
So are you gunna get ur car seem welded (spot welds along the seams) or get random useless spot welds here and there, to save striping it down to the shell.
Someone please explain how seem welding is different to spot welding along the seems of the chassis. Im dying to kno.
Seam welding means you weld along the seam entirely (weld the whole seam).
Spot welding is where you weld in one spot for about an inch then move along the seam and do another small weld leaving parts of the total seam not welded so the welds look like dots along the seam not totally one long weld connected together.
ahh i see, cheers:thumbsup:
however isnt doing a continous weld bad in that it can actualy weeken the metal, and also cause warping?
i know its bad with welded in cages, when mounting the plates to the car, the good cage builders will do in weld inch then no weld then inch weld to keep some strength in the area, cus it can punch through easier if welded all around the plate.

Seam welding involves a MIG and can either be semi seam welded(which I have done to my N14 Pulsar) or solid seam welded. Solid normally stops the car from deforming in an accident, which means the occupants normally take all of the stored energy from an accident. This normally means fatalities and is why crumple zones/safety cells are created in modern cars.
The 3rd pic you posted in Post #49 shows a bit of semi seam welding.
As a car magazine journo myself, car magazines are renown for making the information more understandable for readers. Probably why you were confused.
By the way Spetz, I paid a local panel beater $100 and a carton of beer to semi seam weld my entire car after I removed my carpet/seats/trim :)
yes I was planning to take mine to a panel beater as well
Is it a good idea? Will it offer improvements??
cheers iamhappy46 good info there, cleared that up good for me:thumbsup:
So is it only ever done along the chassis seams, or are there other places that it is done where it improves durability and strenght?
heres that pic again thats the one ur talkin about right.
