Problems solved by technology

[0008] However, due to the limitation of the optical path system, the current laser surface treatment is mainly concentrated on the outer wall surface of parts. For the inner wall treatment, it is generally 3 meters long workpieces. It is extremely difficult to use a laser surface treatment device for the inner wall of a large steel pipe with an ultra-long length of 10 meters.

Abstract

The invention discloses a high-power semiconductor laser surface treatment device for the inner walls of large long barrels. The device comprises a laser generation assembly, a laser beam expander anda laser processing beam type central rotating shaft, wherein the laser processing beam type central rotating shaft is arranged in a to-be-processed pipe fitting during use, and is provided with a shaft internal light guide channel; laser is transmitted through the shaft internal light guide channel after being shaped by the laser beam expander; a translation machine frame is further arranged in the laser processing beam type central rotating shaft, can rotate along with the rotation of the laser processing beam type central rotating shaft, and is used for driving a focusing assembly and a laser turning mirror to horizontally move in the laser processing beam type central rotating shaft; and the length of the to-be-processed pipe fitting is more than 10 meters. For the inner walls of largelong barrel workpieces such as ocean equipment, oil transportation pipelines, chemical equipment, tunneling equipment, coal mining equipment and the like, a high-power semiconductor laser cladding technology is used for enhancing the performances such as the wear resistance, the corrosion resistance and the like of the surfaces of the inner walls of the selected workpieces, so that the service lives of the workpieces are greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of laser surface modification of high-power semiconductor lasers, and more specifically relates to a semiconductor laser surface treatment device for the inner wall of a large long tube workpiece, which adopts a telescope beam expansion system and is suitable for surface treatment of the inner wall of a large long tube workpiece. The length of the workpiece can reach 10m and above. It is a high-power semiconductor laser surface treatment device for the inner wall of a large long tube. Background technique [0002] Large steel pipe workpieces occupy an important position in various industrial fields such as oil pipelines, marine equipment, drainage, natural gas transmission, mining, and tunnel boring. Compared with the outer wall of the workpiece, due to the chemical corrosion and physical erosion of the substances transported in the large steel pipe, the wear of the inner wall is often more serious, which di...
