Ive got an external splined shaft that’s stripped the splines. Was thinking to machine a new spline shaft but would it have to be hardened after machining. It’s about 100mm diameter by about 150mm long about 30ish splines. Also the hub splines it locates into has stripped about 5 splines of it. What type of welding rod would one use to build back up to remachine.

I don't know! The late, great John Stevenson did this sort of work but it's out of my league. Anyone else into repairing splines?

Google is probably your friend here.
Did a quick search with building up splines with weld as the text and got a number of useful hits from reliable sites
Only one I looked at was a thread on the MIG Welding Forum titled Spline Repair. Nice thing about MIG Welding Forum is that its UK based and (usually) doesn't call out anything uber hard to get over here.

You don’t want to use anything too exotic like SuperMissileWeld which is basically just a jumped up nickel rod.

What machine is it for and do you know what caused it to fail. Is the hardening to resist the wear or to increase the strength? How come only five internal splines are stripped? I would have expected it to be all or none! Is the shaft 150 mm long or is that just the length of the splines? How long are the internal splines? What is the form of the spines?

Driveshaft for a 10 ton truck? Or agitator drive for a washing machine? Could make a difference with rod choice.

If a new one would have to be hardened after machining, so would a built up one. At least with new material you know what it is, what it's current state is, and how to harden/temper it

Col21, since there are a lot of splines, I guess they are vee or involute, probably the latter as these can be hobbed like gears.
So, if you plan to machine one, you might check for curved teeth.
