I am building cable plowing blade back up after use. I am looking for a good type of welding rod that will build the face of it back up and take the abuse of being pulled through hard ground. I'm trying not to build this thing back up every other month. What do you all recommend. Could mig if needed or stick.
Build up with 7018 or better, I use mig with metal core wire to build up & reshape then cover with good hard surface wire or rod as suggested above. I use at least 2-beads thick of HS but not over 3 thick if around 60 Rockwell.
If its extreme ware issue I use a hard surface wire with a carbide trickler and trickle carbide into the weld but that has to be put on level and u need carbide trickler.
If not to large I also use O/A torch and borium tube which has carbide chunks inside tube. They also make in a brass type matrix stick kinda like brazing u need flux for it.
You can also buy arc rods with carbide particles in them.
Raw carbide particles are the best ware protection that I've found for underground work.
Hope it helps Greg
Use a good build-up rod that will work harden. A product called railtec comes to mind. After the build up is done hard surface with the rod or wire of your choice. Hard surface rod should never be used for build-up.
