Under such circumstances, on car repair is not going to work.
The recommendation by caradiodoc might work. You mentioned a lot of weld etc and it faisl. Primary reason is because the repair is not perfect.
The crankshaft runs under load of the various drive belts and your crankshaft has been worn out of round. The pulley has to turn perfectly round and your repairs most probably has the pulley turning eccentrically. This would result in a heavy load on the crank pulley bolt etc and they would give way in no time.
The other thing you need to replace would be the timing belt crank sprocket. The impac of the pulley would most probably have damaged it resulting in it not being level and when the pulleys is tightened, it is not at 90 degrees with the crankshaft.
