It looks to me like a crack, it’s quite noticeable when feeling it with my nail:

What part of the bike is that? Stem or Crank?

IANAE - however, that does not look too good. Since it's not a shiny new bit of kit, why not take a bit of paint off to be sure?

The weld is cracking; there's too much separation for that to be just a witness crack.

It’s the junction between crank arm and spindle.
Thx all for feedback!

Good excuse to get some 48 spline cranks.

These are a good deal:-

Nah, bearings on these type of cranks don’t last long, I’ve got an old set of Hone’s lying around, will just stick a 28t chainring and with external bb it should last forever, the bike has a 73mm euro bb luckily.

Bearings in mid BBs last way better than most as the tube spacer eliminates side loading.

Edit - ah... is it a threaded BB? If so, I’d agree - bearings to fit that shell and axle size are too wee unless you can find one of the outboard cup types to suit it.

Yes, it's a Scott Voltage YZ 0.2, 73mm shell and threaded 🙂
There are outboard bearings for it, I'd go that way if I hadn't the Hone cranks laying around: http://dartmoor-bikes.com/hardware/bb-s/euro-pro-ex-bb
