I have welded leaf springs with super missle weld and it held. It is expensive(about 15.00 a pound)but should do the job and be cheaper than a new spring.
By the way, I didn`t do any of that heat treating stuff either.

The spring will have failed where the stresses are the highest. You can get replacement springs (new) for about $25. I got mine from Carter & Grunewald, but have seen them other places as well.

Frank, just vee it out and weld it, then grind it flat on the underneath side and lay a plate the same width on there and weld only on the sides, edges, not across (that would weaken it). Use 1/8" low hydrogen rod and make plate about 3" long mild steel (same thickness + or -). Put a cushion on it and bounce it real good to test. If it holds, it should be okay and pretty cheap repair.

Hi Frank, It depends on where on the spring that it broke on how well the weld joint will last. If it's in a high stress area, towards either end, then the chances of the spring lasting for any length of time will be less and maybe not even last. Then you have consider that after you anneal the spring to weld, it then again needs to be harden and will it have the same spring quality as the oppisite side has? Chances are no it won't. If you would reharden both springs at the same time that would be best.

I would try and modifiy another spring if a new one wasn't available. Or you can have a new one made but there again there will be a difference in spring quality from one side to the other. Me I would repair my own.

To anneal metal, heat to 1500 degrees and let cool very slow (about 2 hrs to cool). This should be done twice for the best annealing. Clean base metal 1" on either side of V-Notch joint and Weld spring. Then heat too 1500 degrees letting the steel soak heat evenly about 5 minutes, then quench in oil. This hardens the spring. Reheat one more time to 700 degrees, again heat soaking evenly about 7 minutes, then quench in potassium nitrate. This adds temper to the spring.

You can get temp sticks at any welding supply company.

As you can see it's an involved process but it can be done.

The base metal should be welded with an electrode that matches the base metal's chemical composition. If the owner were out in the middle of a jungle it might be worth all the effort to do a weld repair of this nature. But since replacement springs are available I go for a new one.
