Oil drill collar repairing

Product description：

The main failure modes of drill collars are fracture and poor toughness of the material. Therefore, it is necessary to periodically quench the drill collar and repair the failed drill collar by cladding.

WILA Laser uses a laser beam to melt the coating material and thin-layer base material. After rapid solidification, it forms a cladding layer with extremely low dilution and roughly the same composition as the coating. The alloy cladding layer can be formed on the surface of the drill collar. Thereby improving the wear resistance, corrosion resistance, heat resistance, and oxidation resistance of the surface of the substrate material. It can also restore the worn drill collar to size, similar quality, and same performance repair.

The drill collar processed by laser cladding repair technology has less heat input during cladding, which has little effect on the overall structure size of the drill collar, will not cause deformation of the drill collar, and the laser cladding layer is very flat, which can not only damage the surface The dimensions of the parts are restored as required, and the surface corrosion resistance and wear resistance are also improved, thereby prolonging the service life and saving the cost of purchasing new products.

For new or unexpired drill collars, WILA Laser's new laser hardening technology uses high-energy lasers to quickly scan the surface of the workpiece, and quickly absorb energy in a small area with an extremely thin spot size on the surface of the workpiece to reach high temperature and achieve a low temperature in an instant. High-tech quenching. Not only the drill collar is repaired, but the surface hardness, wear resistance, strength, and high-temperature performance of the drill collar after repair are significantly improved. At the same time, the drill collar can still maintain good toughness and make it have good wear resistance. With the characteristics of high impact toughness and high fatigue strength, the service life is greatly improved compared with the original parts.
