For rotationally symmetric parts an increasingly use of the can be seen. The technical system requirements and the welding process do not differ from CD-welding with a welding projection. Rather, the advantage is to be found in a much simpler weld and tool design.
The parts need to be designed with a slightly overlap. If one part has a machined phase, the parts show a self-centering behavior once the pre-load is applied. During the discharge of the electrical energy the joining procedure is the same as seen by CD-welding with a weld projection. The joining is formed at the lateral surface of the parts and can reach a length of up to 3 mm.
• USP GLAMAtronic
• Easy weld preparation
• Vertical weld orientation
• Weld length of up to 3 mm
• Sintered parts also possible
The following drawing shows two components before and after press fit welding. The metallographic picture shows a vertical joint zone which results at press fir welding.
