Abstract

A method and a device () for welding at least two profiled sections () for window or door frames or leaves uses a heating unit () introduced between the profiled sections () to be joined. At least two heating elements () of the heating unit melt the profiled section ends () at the end surfaces to be joined. In order to chamfer, in particular remove, a profiled section edge layer () of the profiled section ends () along the layer surfaces () thereof, at least one tool, in particular at least one cutting blade (), is arranged on the heating elements () and is moved such that the material () to be melted is displaced into the profiled section interior () or into the interior () of the profiled section chambers (). A compression device compresses the profiled section ends ().
