The invention discloses a monitoring system suitable for laser wire-filling welding, which comprises a telescopic bracket connected to a laser emitting mechanism, a bracket, a rotating bracket, an electromagnetic ultrasonic emitting probe and an electromagnetic ultrasonic receiving probe. The two ends of the support are respectively connected to the telescopic support and the electromagnetic ultrasonic transmitting probe, and the electromagnetic ultrasonic transmitting probe is connected to the wire feeding tube; one end of the rotating support is connected to the support in rotation, and the other end Connected to the micro-camera, the rotating bracket drives the micro-camera to rotate by rotating relative to the bracket; the electromagnetic-ultrasonic receiving probe is arranged on the workpiece, and it cooperates with the electromagnetic-ultrasonic transmitting probe.
Description
technical field [0001] The invention belongs to the related field of electromagnetic ultrasonic technology, and more specifically relates to a monitoring system suitable for laser wire-filled welding. Background technique [0002] Laser wire-filled welding refers to the method of filling welding materials to form welded joints while laser irradiation. Compared with non-filling wire welding, laser-filled wire welding has the following advantages: 1. It solves the problem of strict requirements on workpiece processing and assembly ; 2. Realized low-power welding of thicker and larger parts; 3. By adjusting the composition of the welding wire, the microstructure and performance of the weld area can be controlled. However, the stability and accuracy of wire feeding during laser wire-filling welding cannot be guaranteed, resulting in the inability to form a good weld structure. [0003] In order to confirm the stability of the wire feeding mechanism during the welding process, i...
