Problems solved by technology

During the repair process, due to unqualified insulation strength and other failures, there was a large backlog of ignition wires to be processed. However, due to insufficient repair capacity, especially the insufficient welding ability of the contactor, it has not been possible to carry out in-depth repairs on the ignition wire as a whole, resulting in waste of resources

Abstract

A laser welding method for contactors applied to ignition wire repair belongs to the technical field of engine repair. The laser welding method includes the following steps: determining the technological parameters of laser welding, setting absolute coordinates, and closing an optical shutter to block laser; emitting laser, delaying to wait for the stabilization of beam quality, opening the optical shutter, and rotating at angular velocity; carrying out linear interpolation, closing the optical shutter, and returning to the origin.

Description

technical field [0001] The invention belongs to the technical field of engine repair, in particular to a laser welding method of a contactor applied to the repair of ignition wires. Background technique [0002] The ignition wire is assembled on the main engine of the aeroengine and is an important component of the electrical system of the aeroengine. During the repair process, due to unqualified insulation strength and other failures, there was a large backlog of ignition wires to be processed. However, due to insufficient repair capacity, especially the insufficient welding ability of the contactor, it has not been possible to carry out in-depth repairs on the ignition wire as a whole, resulting in Waste of resources. [0003] Compared with traditional mechanical processing, laser welding has the advantages of fast processing speed, small thermal deformation and heat-affected zone, no noise during processing, no pollution to the environment, and processing of complex-shap...
