Abstract:
A method for producing a hollow valve of an internal combustion engine may include providing a hollow valve stem, a valve cone, and a valve bottom; pushing the valve cone over the valve stem via a press fit, wherein the valve cone includes an outer surface transitioning to the valve stem to define a testing surface; and welding the valve cone to the valve stem via at least one of a laser beam and an electron beam, wherein the welding occurs such that no melting of the outer surface in the region of the testing surface of the valve cone occurs.
