    Both will work, however don't use hard wire. The welds won't stand up as well as stick or flux core. The knuckles are uaually cast steel of a good grade, preheat the T-1 to around 300F and allow to cool slowly. Most of the dozer blades I work on aren't T-1, so we normally just use a good quallity filler, 70,000 psi rod or flux core without preheating. .

    Most aren't T1. I do one at a time. Just wash the old ones off with a gouging tip , clean it up quick and throw the new ones in and start welding. The piece should be preheated from you washing the old one off. I use E71 M dual shield when I do em or stick if done in the field. Never had one break and they have some play in them so don't worry if they aren't 100% perfect. Sometimes the new ones have extra material which compensate if you just cut the tubing off instead of washing the old end out. Dave
