ABSTRACT:
In the manufacture of welded corner joints between hollow plastic sections shaped parts are used which abut against the plastic sections during the heating-up operation and also during the welding process. In this way the result is achieved that the weld bead or plastic rim which forms during the welding, is pressed into the hollow cavity (19) or into the hollow cavities so that a subsequent operation for the purpose of removing the weld bead is not necessary.
