In fact,in conventional laser vibration welding, the collimated beam is vibrated by a uniaxial galvanometer.
And the spot focused by the focusing mirror is moved with the welding head to move relative to the workpiece to form a weld having a certain amplitude, frequency and offset.
Besides, comparing to the first two vibration welding modes, the double wedge mirror rotational vibration welding produces a spiral weld seam.
By the vibration module mounted between the collimating mirror and the focusing mirror.
So that the focusing spot moves while the welding head moves.
When the focal length is the same, the larger the torsion angle is, the larger the vibration amplitude is.
Therefore, double wedge vibration welding allows the weld joint to be widened while achieving better weld formability.
