Neighbor came over earlier with a broken shaft from some machine. The shaft parted from a torque load but they swapped it with another identical shaft and now this repaired unit is going back as an idler until its replacement arrives. Maybe a conveyor belt? I dunno.
Anyway, I beveled the ends, lined it up in a vee block to get it straight and then filled it up with ER70s6 and the TIG box. Shaft came out straight as an arrow (go me) but then I realized this was probably 1045 vs the 1018 I was anticipating. I have couple questions-
1) which filler would one use to weld up 1045?
2) are pre/post heat specs super critical? I can't toss it in the heat treat oven, there's a rubber widget bonded to one end.
3) in the interest of letting such a weld cool as slowly as possible, what mediums can a guy use expediently to somewhat insulate it? Sand?
If the shaft fails at my weld I'll put a collar over it until the new part arrives, that was their second choice anyhow, but I'm just curious as to how I could improve.
