The invention provides a smooth wire coaxial laser cladding method for a valve sealing surface, which is characterized in that a wire for smooth wire coaxial laser cladding, which has the diameter of 1.2-1.6 mm and is suitable for valve substrates made of carbon steel and stainless steel, is obtained through a bending-powder feeding-rolling sealing-diameter reducing process on the basis of optimal design of chemical components of a powder core wire. Afterwards, annular light spots are used for conducting preheating treatment on the powder core wire before laser cladding, meanwhile, double annular light spots with independently-adjustable middle core power / ring core power are adopted for conducting coaxial laser cladding forming on the powder core wire, the single-layer cladding thickness reaches 2-4.5 mm, the splashing phenomenon is eliminated, and the stability of a molten pool is improved; and high-quality and high-efficiency surface hardening treatment of the sealing surface of the valve is realized.

This invention discloses a cutting fixture and method applied to the removal of compressor moving blades in a gas turbine. The cutting fixture includes: a support module positioned on the compressor disc, the support module having a hollow groove suitable for the compressor moving blade to pass through, with a gap between the hollow groove and the compressor moving blade; a guide module disposed on the support module, suitable for moving axially along the compressor disc; and a cutting module disposed on the guide module, having a cutting end positioned directly above the gap during cutting, suitable for axial cutting along the compressor disc via the guide module. The support module of this invention positions the cutting module, eliminating the need for operators to hold an angle grinder. The guide module provides linear guidance for the cutting module, ensuring that the cutting groove cuts linearly along the compressor disc axis, preventing the cutting angle from wobbling due to unstable handling and avoiding accidental damage to the compressor disc.

A pricking needle is fixedly connected with a support, the sharp edge of the pricking needle faces upwards, a can pressing piece is connected with the support in a hinged or sliding mode, and the can pressing piece is used for driving the paint spraying can to move downwards, so that the lower end of the paint spraying can is pricked on the sharp edge. Compared with the prior art, the paint spraying tank has the advantages that the discharged paint directly faces downwards and quickly settles, the paint possibly splashing upwards is blocked by the paint spraying tank, splashing and gasification of the paint to air are eliminated, the gasification space and the gasification equivalent are extremely small, the paint subjected to pressure relief of the paint spraying tank directly faces downwards, and the paint spraying tank is easy to receive, safe, environmentally friendly and capable of relieving pressure, and the upper end of the support, the tank pressing piece and the like are not prone to being polluted by the paint.
