The expense of having one welded is not worth it just get another crank.

Yes, it can. Years ago I had Standard Crankshaft of Charlotte NC do one for a 52 MG. That's all they do and it was cheaper than buying a replacment.
i am sure it can if is financiably viable. A few years back I got talking to an old railway engineer at a show. He told me many of the modern diesel trains break cranks sitting idling in the stations. He told me of some that had broken and welded cranks in as many as 4 places.
But, I would advise looking in a wreckers yard. Very often they have good cranks in engines that have been frozen and cracked. or in tractors that have been burned.
Good luck....Sam

Maybe, depending on where the break is and how bad it is. And maybe if it is super rare. I would be talking to someone with experience in welding and remachining cranks to see what they thought about your individual problem. My guess is that it would be expensive and technical. And the result might not be as strong as an original crankshaft.
Unless it was a lot less expensive to have a crankshaft welded, I would start looking for a replacement shaft that could be used as-is or which could be machined for the next undersize. I also would try to figure out what made the original crankshaft break. I have had bearings spin, which damaged crankshafts a couple of times, but I have never encountered a broken crank in my 50+ years of tinkering. Maybe I have just been lucky...good luck to you!
