Guess i wont do it!

You don't heat it to that point. It's to extract the moisture that build up in the steel. Heating steel to "sweat" it is very common practice. I do it quite often, it allows you to produce a cleaner weld as well.

...I'm talking about welding the spring.

Its a 1971 torino. Just a 302 with a upgraded comp cam, headers intake and have a 4 barrel carb to put on. Have a 429 waiting to go in..dont know when though. haha. Has a hole in the hood for the cobra jet shaker we have too.

Nice, my buddy turned me in to a die hard 351 fan haha He had a Clevland in his 71 Gran Torino till it got wrecked. Just put it in a Mach 1 that should be out of paint soon

Not to mention heating a spring up enough to melt the metal is going to soften the spring rate like crazy...

there isn't a filler material for welding spring steel per se. the reason why is because the metal in a spring is tempered. that is to say it receives a special heat treatment that allows it to be tough but yet flex. when you heat the spring during welding, you are screwing up the temper. if the weld doesn't break, you will have a break in the spring itself just past the welded area on one side or the other. basically, for this not to break, it would need to be re tempered.

as far as filler material goes, they all are unsuited for this purpose, but i think the best choice would be stainless 304.

Calm the fuck down. Even if the welded area cracks and falls off there is still enough spring there to avoid 'total annihilation'.

Exactly.

Plenty of people run cut pigtail springs without bothering to weld them. I've seen some creative solutions, from wire, to self taping screws and brackets. Either way, even if the weld brakes, the car hits a huge bump, the suspension unloads, and the spring falls out, the worst that will happen is the car will bottom out on the bump stops.

Will it handle well with cut springs? Possibly not, but it certainly won't be as bad as many love to claim. And is he putting himself, or anyone else at risk? No.

And, he will probably be in the car when the spring breaks.

Not trying to crap on your parade, I just don't want to see anyone get hurt.

[Larzzz]

Yes this is very true.

Sorry, thats not how it works. One, if anything you should be pre-heating the springs. But it all about the filler material you are using. Its not designed to flex. Be very careful doing this. That spring will be under pressure when it breaks which could be very bad news. I've been welding for years and habe gone to school for it. Its much more complicated then geting full penetration.

[Larzzz]

Hahahaha!

There's no way this could end poorly.

Im not even done welding it. ill be getting full penetration and ill be melting the shit out of it to get a good bond/fusion
