Abstract

The invention relates to a system and a method for online detection of fusion depth of a laser welding head. The system comprises a control terminal, an optical detector, a laser controller, a platform controller and a control arithmetic unit, the control terminal is connected with the platform controller and the laser controller and transmits information, and the platform controller and the laser controller are connected with the optical controller and transmits information. The optical detector is connected with the control arithmetic unit and transmits information, a data processor is connected with the control terminal and transmits information, the laser welding head is moved to a working coordinate, an initial focus coordinate of a welding position is searched from top to bottom by taking a light emitting surface of a laser focusing mirror in a Z-axis direction as a reference, and an initial focus value is Z'; welding is carried out at the welding focus coordinates according to preset parameters, the optical detector is used for collecting the current coordinate value of the welding point on line in the welding process, and the difference between the focus value Z'and the current coordinate value fed back by the optical detector is the current fusion depth value. According to the system, the technological parameters are automatically adjusted, the production efficiency is improved, the yield is increased, and offline detection is reduced.

Description

technical field [0001] The invention relates to the field of laser welding, in particular to a system and method for on-line detection and melting of a laser welding head. Background technique [0002] In recent years, thanks to the rapid development of high-power solid-state lasers, laser welding is gradually replacing the traditional welding process, and the application of laser welding in the field of modern manufacturing is becoming more and more popular. The new energy and automobile manufacturing industries put forward higher standards and higher requirements for laser welding equipment in terms of welding process quality. [0003] In the detection of welding quality, traditional methods include ultrasonic testing, magnetic particle testing, and X-ray testing. The detection of welding penetration makes it difficult to guarantee the welding quality. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the present invention pro...
