ABSTRACT:
A process for producing a remelted and chilled camshaft comprises the steps of melting a sliding cam surface by TIG arc and forming a chill layer by self-cooling. When two adjacent cams are in positions at which a mutual influence from the magnetic arc blow of the TIG arc current applied to the cams can be felt, a melting current applied to two arc torches is alternately changed so that the sliding cam surface of one cam is melted while the other cam is in the nonmelted state.
