Laser hot cladding process of blade

Abstract

The invention relates to a laser hot cladding process of a blade. The laser hot cladding process comprises the following steps: (1) cleaning the surface; (2) detecting an abrasion area and a crack area of the blade by utilizing a detector, recording a to-be-repaired position, and imputing the to-be-repaired position to a human-machine interaction interface of a controller; (3) performing laser cladding, namely powering on a powder feeder and a laser, and controlling the movement of the laser and the powder feeding amount by utilizing a control instruction of the controller; and (4) subsequently processing. The powder feeder and the laser are simultaneously controlled by the controller so as to guarantee the synchronism of movement; meanwhile, the powder feeding amount, the laser input energy, the repetition frequency and the laser scanning speed can be precisely controlled, the sensitivity is high, a traditional way for manually adjusting a knob is substituted, the control efficiency is greatly improved, the laser cladding quality is guaranteed, the abraded blade can be repaired, the application performance of the blade is further improved, and the abrasion resistance of the blade can be improved.

Description

technical field

[0001] The invention relates to the technical field of remanufacturing blades, in particular to a laser thermal cladding process for blades. Background technique

[0002] A turbine is an engine that uses fluid to impinge on the impeller to rotate to generate power. It can be divided into steam turbine, gas turbine and water turbine, and is widely used as a power machine for power generation, aviation, navigation, etc. The blade is one of the important parts of the turbine. The quality of the blade affects the actual performance of the turbine. However, in the actual working process of the blade, due to the scouring of the fluid, the surface of the blade is worn, which eventually leads to the work of the turbine. The performance decreases, which reduces the working efficiency. For the blades with serious wear, they need to be replaced in time, which will also lead to higher maintenance costs.
