Compared with surfacing, spraying, electroplating and vapor deposition, laser cladding has the characteristics of small dilution, compact structure, good combination of a coating and a matrix, more suitable cladding materials, large particle size and content change and the like, so the application prospect of the laser cladding technology is very wide.
From the current application of laser cladding, it mainly applies to two aspects: firstly, surface modification of materials such as gas turbine blades, rollers, gears and the like; and secondly, repairing the surface of the product, such as a rotor, a mold and the like. The related data show that the strength of the repaired component can reach more than 90 percent of the original strength, the repair cost is less than 1/5 of the replacement price, more importantly, the repair time is shortened, and the problem of rapid repair of the rotating component which is required to be solved when the large-scale enterprise major complete equipment continuously and reliably operates is solved. In addition, the surfaces of the key parts are clad with the super wear-resistant and corrosion-resistant alloy by laser, so that the service life of the parts can be greatly prolonged under the condition that the surfaces of the parts are not deformed; the laser cladding treatment is carried out on the surface of the die, so that the strength of the die is improved, the manufacturing cost of 2/3 is reduced, and the manufacturing period of 4/5 is shortened.
The main problems and drawbacks of the prior art include:

Under the conditions of determined process, equipment, environment and the like, a proper working distance needs to be kept between the end face of the cladding coaxial powder feeding head and the processing surface, but because the design of the cladding coaxial powder feeding head generally presents a certain taper, or interference of various interfaces or pipelines attached by peripheral derivation, or limitation of a working space, when the conventional measuring tool is used for measurement, the measuring tool cannot be effectively contacted with the surface to be measured, so that a larger error exists in size measurement during data observation and reading, and the cladding quality is influenced.

Preferably, the serial numbers are arranged in order from 1 in size, and each step surface corresponds to one serial number. And the overall outline size and the integral inclination angle of the serial number are small, so that the interference in space or structure can be effectively avoided.
Preferably, the lower surface of the stepped auxiliary tool is a plane and is used for being attached to the surface to be processed of the part.
Preferably, the upper surface and the lower surface of the stepped auxiliary tool are in surface contact with the end surface of the cladding powder feeding head and the surface to be processed of the part.

At the moment, if the current working distance is not consistent with the height required by the actual process, the height can be quickly adjusted and measured again by adopting the stepping function of the movement mechanism. In addition, the upper surface and the lower surface of the tool are in surface contact relative to the contact form of the end surface of the cladding powder feeding head and the surface to be processed of the part, and finally, the observation and reading of the working distance can be realized efficiently and accurately.
