Rim damage

Hello. Both rear rims 9×18 Segin are slightly damaged. Is the rim doc welded or only spatted and how is the durability of the repair? I could imagine that it blows out again at the tyre moth machine. The rims are forged, can one even weld on them? Price should be 80,-€/ rim plus tyre disassembly and assembly. New price 550,-€/ rim piece. Maybe someone has long-term experience? Color differences? Or no more h Look until a real damage occurs? MfG
