Process for welding profiles, in particular plastic profiles

摘要

A method for welding a first member and a second plastic member, the first member having a first surface and the second member having a second surface which are to be welded to each other, the surfaces having different shape configurations nonconforming to each other includes positioning the first member transversely with respect to the second member with the nonconforming surfaces facing each other, heating the first surface at a welding temperature and transforming the shape of the first surface such as to at least partially conform it to the shape of the second surface, heating the second surface at a welding temperature at the surface area corresponding in size and contour configuration to the first surface and at the location where the first surface is to be welded to the second surface, and welding the first and second heated surface together.
