Gliding edge profile

Abstract

A gliding edge profile for winter sports equipment, such as 7 for example, skis, snowboards and sledges, includes two component parts connected at an angle to one another along their longitudinal edges. The component parts are made of different materials to suit their properties to the stress at hand and can be joined together by laser beam welding, electron-beam welding or plasma jet welding so as to hardened and/or tempered at least in the area of the welding seam.
