I would almost just suggest replacing the block if you had some reason the engine was going to be out and apart. I don't think it can be properly welded without heating it up, and then properly bringing temperature back down after it's welded. You might want to find out what it costs too. One time I had a block repaired, and I made the guy promise it would not distort the cylinders out of round. I took it straight from being welded to the machine shop where they stuck it on the Sunnen hone, made a couple of passes with the stones and showed me that it had been pulled out of round. The welding shop didn't charge me, but I had to get another block machined and start over.
