摘要：A waveguide (20) for plastic welding comprises an entry end (22) defining anentry face for laser light, an exit end (24) defining an exit face for laser light as well as afirst (26) and a second (28) inner face which are arranged between the entry end (22) andthe exit end (24), which are arranged opposite to each other and by means of which laserlight can be reflected. A first distance between the entry end (22) and the exit end (24)defines a length (L) of the waveguide (20) and a second distance between the first (26)and the second (28) inner face defines a thickness (D) of the waveguide (20). In a firstembodiment, the exit end (24) is arranged opposite to the entry end (22) and a centralplane (M) of the waveguide (20) extends centrally from the entry end (22) to the exit end(24). The first inner face (26) comprises a continuously curved, concave shape so that athird distance (D1) between the first inner face (26) and the central plane (M) of thewaveguide (20) varies continuously from the entry end (22) in the direction of the exit end(24). In an alternative embodiment, the first inner face comprises a continuously curvedconcave shape which is part of a first spiral, especially a first natural spiral, so that a radiusof the first spiral from a point of origin of the first spiral to the first inner face variescontinuously along the waveguide.
