Ultrasonic stud welding
Ultrasonic stud welding is the suggested option when similar plastic parts need to be welded at single or multiple localised points.
When resin selection, size or part complexity inhibit use of other methods, stud welding may provide a good solution.
A shear joint variation is used in stud welding. An oversized stud is ultrasonically driven into a hole, and welding occurs along the circumference of the stud; the weld strength is related to stud diameter and depth of the welding. Maximum tensile strength is achieved when the depth of welding reaches half the stud diameter. This method can be used to lock a dissimilar material in place. The studs can be moulded into the part or can be separate pieces. Please visit our Youtube Channel
Basic Guidelines for Ultrasonic Stud Welding
- Low pressure / power
- High Amplitude
- Multiple stud welding is possible if the pitch is small
