Problems solved by technology

[0003] At present, after the wire mesh has been used for a long time, cracks are prone to appear on the surface of the support rods. If the cracks are not repaired, it will affect the overall strength of the wire mesh and reduce its service life. However, the existing repair methods are cumbersome to operate and the repair effect is poor. The effective application of laser repair technology to the repair of cracks is a problem that those skilled in the art need to solve

Abstract

The invention discloses a laser repair technology for cracks of a screen support rod. The laser repair technology comprises the following steps: A. polishing the surface of the support rod so that thecrack edge is smooth; B. preheating the support rod overall; C. cutting the crack part with a laser cutting head; D. fusing parent materials at the crack part by laser to form a molten pool; E. continuously overlapping and scanning the support rod by a quick transverse carbon dioxide laser in a preset powder feeding manner; and F. placing alloy powder into the molten pool for laser cladding, so that the repair is finished. The laser repair technology disclosed by the invention is simple and good in repair effect, and the integral strength of the support rod can be improved; and the screen strength is further improved.

Description

technical field [0001] The invention relates to the technical field of laser repair technology, in particular to a laser repair technology for cracks in wire mesh support rods. Background technique [0002] The laser processing technology gradually replaces the traditional technology to achieve a breakthrough improvement in product quality (shown as higher product strength, more reliable product stability, more accurate printing accuracy, printing speed, printing size, stronger product wear and tear) Product corrosion resistance and more beautiful appearance quality), can also greatly enrich the production specifications, meet the special requirements of some industries, and have a wide range of application prospects. [0003] At present, after the wire mesh has been used for a long time, cracks are prone to appear on the surface of the support rods. If the cracks are not repaired, it will affect the overall strength of the wire mesh and reduce its service life. However, the...
