Abstract
A high frequency welding method comprises providing two plastic workpieces to be welded together with respective ribs which face each other, extend to the same height and have their surfaces opposite their facing surfaces inclined such that their thicknesses decrease toward their tops, and applying high frequency vibration to the ribs by positioning a high frequency welder horn such that the bottom of an annular groove of the horn having an arcuate sectional profile is pressed against the tops of the ribs.
