Abstract
In a process for producing a surface remelted chilled layer camshaft by using a high density energy irradiation and self-cooling, a cam is rotated around the center axis of the camshaft and a position of a torch for the irradiation (e.g., a TIG arc torch) is controlled so as to form an angle between a tangential line of the cam surface and a horizontal line at a melting position in a lower side of the horizontal line in a direction opposite to the camshaft rotation direction being from 30.degree., preferably 20.degree., to zero degree.
