nick, adding radweld seems a good idea but there are complications afterwards,the radweld after atime will go hard in the water system within the smaller waterways that run through the engine which can cause over heating and head gasket failure so try,your local scapyard for a replacement they will have a radiator already on the shelf for about £20, its also easy to replace the radiator just two pipes and four little screwbolts down each side of rad. good luck
