Example Embodiment
[0034] The following will be combined with attached Figure 1-6 Specific embodiments of the present invention will be described in detail.
[0035] Such as figure 1 As shown, the welding workpiece is a large structural plate with a thickness exceeding 12 mm. The laser beam is perpendicularly incident on the upper surface of the workpiece to realize deep penetration welding, and at the same time, ultrasonic vibration is applied to the workpiece to be welded and the molten pool area to achieve high-quality connection of ultrasonic-assisted laser deep penetration welding of large thickness flat butt joints.
[0036] In this embodiment, the method for ultrasonic-assisted laser deep penetration welding of plates includes the following steps.
[0037] Step 1: The first base material 10 and the second base material 11 are processed to form the butting end surface, and a series of inclined semicircular grooves 2 are processed on the butting end surface to remove the upper and lower surfaces ...
