Punches steel hard enough to weld it

Joey Fucknuts punched the steel plate, deforming it greatly. And he punched it again. And again. He beat the metal against its supporting frame, welding it into place not with fire, but with pure physical force. Working it cold, so it kept its crystalline lattice and maintained strength without requiring any tempering or annealing.

He did not understand any of these concepts. He just thought that it didn't make sense to work the metal with tools when his fists were good enough.

CLANG!

He punched it again, each of his knuckles sending sparks flying. The metal caved in further. Taking form. Becoming something that he understood as clearly as any man understands his god.
