Axial Oscillation Friction Welding
Friction welding with axial oscillation generates relative motion between joining partners by high-frequency axial vibrations, enabling the joining of non-rotationally symmetric parts. It offers precise control of final position.
Physico-Chemical Working Mechanism
Axial oscillation moves the tools along the weld, allowing continuous contact and separation between the joining partners. This leads to uniform deformation and better control of the weld zone.
Metallurgical Relevance & Risks When Welding
This method is especially useful for parts with complex shapes that can't be done by rotary friction welding. Wrong settings for frequency or amplitude can cause uneven deformation and poor control, leading to risks like cracks or inconsistent weld quality.
Workshop Practice & Action Instructions
Use a frequency of 50 to 100 Hz and an amplitude of 0.1 to 0.3 mm. Make sure the oscillation is aligned exactly along the weld. Keep an eye on deformation and end position to ensure high weld quality.
