　　The research on welding quality control is an important component of welding process automation. Due to the increasing demand for automation and intelligence in welding processes, controlling welding quality has become particularly important. In recent years, although the level of welding automation has improved, some special welding tasks are difficult to operate with commonly used welding robots in industry, and currently rely on manual labor to complete. So, a simple and robust weld seam tracking algorithm is particularly important. Now introduce a welding robot based on feature point detection for weld seam tracking algorithm. This algorithm is used in welding robots and can be applied to most complex and irregular welding workpieces.

　　The weld seam tracking algorithm based on feature point detection is achieved using laser displacement sensors, making the sensing system compact and simple.

　　The steps of this method are as follows:

　　1. The slide table drives the laser displacement sensor to move, achieving scanning of the weld position.

　　2. During the scanning process, the laser displacement sensor transmits the image to the industrial computer for storage and computation.

　　3. The industrial computer transmits the planned motion trajectory to the welding robot.

　　4. The welding robot automatically moves and welds according to the planned path.
