I would really not recommend welding springs. It might be possible and it might last for a while, but it will surely create stress risers due to variation of the weld
metal to the spring base metal and the fact that the springs temper has been altered in the weld area. Those create fatigue cracks down the road.
A broken spring could put you into an abutment or an oncoming car or Semi and that could make for a very bad day. I would install a used spring before I
welded a old one up.
