Brush type seal robot welding system based on ultrasonic detection technology

Abstract

The invention discloses a brush type seal robot welding system based on the ultrasonic detection technology. The brush type seal robot welding system based on the ultrasonic detection technology comprises an ultrasonic detection module. An ultrasonic analysis module is electrically connected with and communicates with the ultrasonic detection module and a robot control module. A laser welding module is fixedly connected with the robot control module. The ultrasonic analysis module scans a welding surface of a row wire root of a brush type seal through ultrasonic flaw detection equipment and sends wave signals obtained after scanning to the ultrasonic analysis module to carry out welding area positioning, welding seam tracking and welding penetration detection. Operation parameters are determined and sent to the robot control module. The robot control module works in cooperation with the laser welding module to complete welding operation. Welding area positioning, welding seam tracking and welding penetration monitoring are carried out through the ultrasonic detection technology, and automatic welding is realized in combination with a robot welding system, so that the welding quality is fully guaranteed, and meanwhile the welding work efficiency is improved.

Description

technical field [0001] The present invention relates to a welding system, in particular to a brush seal robot welding system based on ultrasonic detection technology, which uses ultrasonic detection technology to track the weld seam, and cooperates with the robot welding system to complete the brush seal automatic welding process, especially suitable for steam turbines and The field of brush seal manufacturing for gas turbines. Background technique [0002] Because of the small sealing gap, wear-resistant flexible brush wire material, good sealing performance and longer service life, the brush seal is widely used in the high-speed dynamic sealing field of turbomachinery, especially for steam turbines and gas turbines. In the field of sealing, it can replace the original hard tooth seal, improve the sealing efficiency, and prolong the service life of the equipment. It is one of the key technologies in the development of modern advanced turbomachinery. [0003] The traditiona...
