Welding Spring Steel??
Does anyone know if/how you can weld spring teel. I have a leaf spring broken on my off-road buggy and in my experience, once welded, spring steel
breaks again quite quickly right next to the repair.
Any help will be appreciated.
Thanks.

It'll happen exactly as you say.
Welding spring steel will remove the springyness.
Being more technical; the heat required to weld the steel will locally anneal it hence reducing any 'strain recovery' behaviour and
f@*king it up good and proper.
Buy a new one unless you have the facilities to weld and then re-heat treat. Although it would probably still break right next to the weld even then.

Any welding will muck up the steel's temper - and even if you heat-treat it, the weld is unlikely to be carbon steel so won't take
tempering.
Most spring repair shops just replace the broken piece - take some stock material of the right width & thickness, cut it to length and shape it,
then re-temper.
It's worth asking the cost, as it may be cheaper than you think.
The alternative is to find another spring that you can canibalise for a new leaf.
