Description

technical field

[0001] The invention belongs to the technical field of laser rapid repair, in particular to a laser rapid repair method and equipment for aluminum alloy guide vane defects. Background technique

[0002] Aluminum and aluminum alloys have the advantages of high strength and good corrosion resistance, and are widely used in aerospace, aviation, petrochemical and other industrial fields. As an application of aluminum alloy materials, aluminum alloy blades may suffer from various damages during processing and use, such as point defects, line defects, and block defects. Generally, point and line defects are mainly concentrated on the surface of the blade, while the top surface of the blade is prone to damage. A block defect caused by cavitation occurs. If the above-mentioned defective blade parts are directly scrapped, it will cause a lot of waste. For this reason, experts have proposed various methods for repairing defective blades, such as laser cladding, vacuum...
