Classic Car Restoration - Resistance Spot Welding Rocker Panels

[Sm1nts2escape]

Damn man. This guy has been in the buisiness for 25+ years? He should know to clean the metal better than that. I'm a beginer and know this :/

@extremepatiesllc I wouldn't be so quick to condemn the welder(machine). There are a lot of factors that go into making a good spot weld. Is the machine set correctly? Timer, amps etc. Is the metal clean between the two layers? Is there sufficient pinch pressure between the metal & the tool? Resistance welders operate on the same basic priciples. If you get sufficient penetration & pressure it will hold. The factory (OEM) cant possibly test every brand of equipment. But I'm sure you know that!

mig welders- migatronic

spot welders- tecna

So the mig welder is used as a spot welder?

RE: extremepartiesllc - OEM "recommends" - that's the key word. It does not mean it's the ONLY welder that will work. It's not the tool, but the skill of the user. The spot welder is made by ARC, an American company. I'll pass aolong your comments to them and post their reply to be fair. BTW - Tom has been at this for 25 years and restored Concours competition cars, but never been in the collision business.

@ccgtvonline ARC makes a pulse welder attached to a slid hammer thats just the cats ass, if you got one i'd sure pay attention to a vid demo of one of those. i know a few old farts that have one, they swear by em.

that spot welder is junk!!!! i worked in a body shop for over 20 years.the glue is good as long as the panel is prepped right,the only welders OEM recommends are pro spot,hirane,elektron,car o liner,any time you have to keep hitting the same spot more than once it is a junk weld period.if i did this repair in the field and that customer gets hit and the weld fails,i am at fault.these are cheap hobbist welders,the others are expensive but do the welds right.

don't quote me on it but i think thats just a special head on a mig welder

[mrbobsshow]

I have a Danmig 220 volt its old as hell but works like a million bucks

That glue is the way to go.

I always thought you were NOT allowed to glue structural components on vehicles????

Not only is that an adhesive; it is also a seam sealer which is very important on rocker panels. It keeps the water out and causing premature failure of those parts. I just did some rockers on a 1991 5.0 and that's the way it was done also. The particular one shown in the video also helps improve the tensile strength of the weld.
