Handheld laser welding machine<\/a> high-energy-density laser beam as the heat source for efficient and precise welding. Because\u00a0\u0622\u0644\u0629 \u0644\u062d\u0627\u0645 \u0627\u0644\u0644\u064a\u0632\u0631 \u0627\u0644\u0645\u062d\u0645\u0648\u0644\u0629<\/a> requires high pre-processing accuracy of the workpiece.\u00a0The position of the beam on the workpiece must not significantly shifted. If the assembly accuracy of the workpiece or the positioning accuracy of the beam cannot reach. When meeting the requirements, welding defects are likely to occur. Which limits the process capability of laser welding to a certain extent. This is because the spot size is small after the laser focused.\u00a0And the weld is narrow.<\/p>

In view of the limitations of the above laser welding technology.\u00a0The market has gradually introduced a double-wedge laser vibration laser welding method. Which is achieved by configuring a special wobble vibration module on the welding head. The application of wobble welding technology can make laser welding more widely used, and can achieve high-efficiency and precise laser welding for larger workpieces and workpieces with wider weld seams.<\/p>

In traditional laser vibration welding, the collimated beam vibrated by a single-axis galvanometer.\u00a0And the spot focused by the focusing lens matched with the welding head to move relative to the workpiece to form a weld with a certain amplitude, frequency and offset.<\/p>

Compared with the first two vibration welding modes, double wedge mirror rotary vibration welding uses a vibration module installed between the collimator lens and the focusing lens to produce a spiral weld seam when the focused spot moved. When the focus focal length is the same, the greater the torsion angle, the greater the vibration amplitude; when the torsion angle is the same, the greater the focus focal length, the greater the vibration amplitude. Double wedge vibration welding can widen the weld seam and obtain better weld formability.<\/p>
