I have replaced radiator 3x since October, new one leaks after couple weeks, other than quality /workmanship of radiator what other factors could be making it leak?

@Paladin Where is it leaking from? Top hose? Bottom hose? Cap? The body? The specific location of each of the leaks will help diagnose the problem...

not from hoses or overflow or cap, has been different parts of the radiator each time, checked for blown head gasket, no indication, going to try different brand radiator next

Are you buying plastic or aluminum? I would suggest minimally 2 row aluminum and ideally 4 row. Perhaps it’s time to go to a radiator specialty shop and have them rebuild & pressure test to make sure it’s usable.
