"yes, weld it"
NOT A CHANCE. I have never seen a Springfield bolt that was cracked.
If this is a bonified crack, You already know that that bolt has one flaw. How do you know that the bolt doesn't have others that you can't see? Such as in the locking lugs,etc
Could it be one of those that was poorly heat treated in the first place when it was made along with those low numbered actions?
Who manufactured the action? Is the serial number still on the receiver ring? There should also be a date on the barrel, just behind the front sight. But this only dates the barrel, not the action. But this rifle could have been rebuilt and such several times during it's life time. So, dating parts is not a sure thing.
I do have an old Lyman loading manual that lists 1903 Springfield serial numbers by manufacturer and date and heat treatment. If you are interested. But this only applies to the actions.
Otherwise, If it was mine, that bolt would end up in the junk box. It's just not worth it.
