Hello, electrical engineer writing, please forgive my stupid question… I need help from

some metalheads. Any recommendation on how to fix my bike fender?

Is this weldable? Or do I need to form a new metal strip and blind-rivet it to the fender? If so, do i just buy sheet metal from the next hardware store?

My main goal is repairing it, even if its more expensive than buying a new fender.

best regards from Norway!
