Possible to weld an axle shaft

Possible to weld an axle shaft

Possible to weld an axle shaft

(OP)
Can anyone give advice on welding an axle shaft? I have been told it will break beside the joint where welded.
 Would it be possible to temper it after welding to bring back the strength.
  Any advice would be appreciated

RE: Possible to weld an axle shaft

Friction welding usually is the best method for axle shafts.  Since it is solid state, it doesn't have problems associated with chemical segregation, low ductility as-cast microstructure, and residual stresses.  Stress relieving and/or tempering are possible stages to use to obtain the necessary properties.

RE: Possible to weld an axle shaft

chupp100,

Do you know the material (chemical composition) and heat treatment of this axle shaft?  If it has already been quenched and tempered or case hardened (either carburized or induction hardened) then welding is not a recommended option.

RE: Possible to weld an axle shaft

I do not know anything about the makeup of the shaft.
It seems to be soft because you can file into it fairly easily. I think the splined ends may be hardened somehow, but not sure about the center of the shaft

RE: Possible to weld an axle shaft

chupp100;
As TVP mentioned above, you must determine the chemical composition of the axle, and if possible, try to have some hardness testing performed to determine the heat treatment condition. Report back with the information and the dimensions of the axle (diameter and location of the failure or break), and we might be able to help you. No promises.

Advice? Don't do it.
With today's aftermarket and shipping, welding is unlikely to be a practical solution.
