Abstract
A process for the bonding of a plastics pipe to another plastics part by ultrasound welding using sound waves which act longitudinally with respect to the pipe axis, while the arrangement of the areas to be welded is substantially parallel to the pipe axis. The welding procedure is combined with the forced insertion of the other plastics part into the plastics pipe in such a way that there is at least some overlap between the exposure to sound and the forced insertion.
Claims10
A process for the bonding of a plastics pipe to a coupling end portion of another plastics part by means of ultrasound welding, which comprises the steps of:
- performing ultrasound welding with sound waves which act longitudinally with respect to a plastics pipe axis while maintaining an arrangement of areas to be welded substantially parallel to the plastics pipe axis, and
- forcing insertion of the coupling end portion into the plastics pipe so that the coupling end portion is inserted inside of and widens the plastics pipe during at least part of the time that the sound waves are being provided during the ultrasonic welding step.
