The article presents the results of development of stand for weld quality control, forming by ultrasonic welding. Proposed, developed and realized stand allowed to carry out the control of the process of forming of weld at ultrasonic welding. Results of controlling are allowed to study the process visually and to set the welding modes providing the maximum weld quality.
The article presents the results of the studies aimed at the development of the apparatus for multi-spot ultrasonic welding of the articles made of thermoplastic materials, which is able to provide simultaneous formation of four non-detachable joints. The performance of four joints in the form of rivets allows considerably accelerating welding at the production and increasing quality of end item.
