On-line detection and size feedback system and method of laser wire filler welding quality

Abstract

The invention provides a laser filler wire welding quality only detection and dimension feedback system and method. The system comprises a controller, a robot, a laser head fixed on the robot, a wire feeding system, an online detection system and a database system, wherein the laser head has a seam tracking system which can achieve mechanical tracking on a welding line and can feed encoder data generated by deflection of the laser head back to the database system; the online detection system is used for detecting workpiece measuring point position data before welding, adjusting the position of the robot according to the location degree deviation from a standard piece and feeding the measuring point position data back to the database system; the online detection system is also used for detecting the quality of the welding line after welding and feeding the welding line quality data back to the database system; the database system is used for inquiring and analyzing the welding quality and the dimension deviation data of a workpiece. The laser filler wire welding quality only detection and dimension feedback system and method can promote the quality of the welding line.

Description

technical field [0001] The invention relates to the field of laser wire-filled welding, in particular to an online quality detection and size feedback system of laser-filled wire-filled welding. Background technique [0002] Laser welding can form a weld with a larger depth-to-width ratio, and the melting and spreading of the filler material makes the weld have better bridging ability. Compared with single laser welding, it can achieve more stable welding quality in plate connection. However, in batch processing, due to the influence of the size of the plate, there will still be unstable factors in the welding quality. Moreover, during the welding process, the quality of the weld seam cannot be observed in real time, and batch defects cannot be quickly stopped, which increases the workload of subsequent repairs. At the same time, due to the inability to accurately grasp the dimensional deviation data of the plate in real time, it is difficult to accurately determine the cau...
