I weld manganese steel to AR Bucket steel regularly. Never done it to stainless. If it's aluminum rod you are talking about, thread it, or drill and rivet it.

I've seen old buckets repaired with stainless. It is very ductile, so cooling contraction won't break something.

If stainless, I might use any of the higher 309, 312 fillers.

I was going to suggest 312 (as it is the maintenance rod) but figured I would go with the facts online so I could blame the reference material. :lol: :lol:

stainless will not TIG weld to aluminum
Actually that's not true [FACE WITH TEARS OF JOY] we regularly do it at work to listen to the noises it makes as it cools when we're bored!

I accidentally tacked a few pieces of 5053 with a li'l stub of 309 rod. It held long enough to get the right rod and tack it again.

Stainless can be welded to aluminum, but the process is a blast. Literally. Explosion welding. I welded a bunch of transition couplers (socket weld, 304N on one end, and 6061-T6 on the other) on a cold-box, and each one of these expensive little bastards came with an adhesive backed permanent-mark temperature scale on it, so you knew if you'd overheated it.

And that is my point, it doesn't TIG weld, yea I know someone who picked up a sst wire and shoved it into an aluminum weld, (wasn't me).

However I did shove Inconel 82 into a titanium coupon just to see what would happen so I've been there too :lol: I posted a pic of that recently

Manganese is hard stuff. it work hardens. The more it is abused as in a rock crusher, the harder it gets. I see it most in grouser stock. Grouser stock is used to replace worn grousers on bulldozer shoes, as wear edges on earth moving buckets. I don't wear loader buckets quite as fast as they might in a rock quarry. I cut the cutting edge of a loader bucket in a straight line and weld on a piece of 1.5" grouser stock as a fresh cutting edge.

I recommend 7018, or Dualshield. Stainless is a great choice, but expensive. The one on my loader now broke in two places welding it on. I suggest 8' pieces be cut in three pieces before welding. A high preheat on the bucket floor would certainly help.
