Application of laser cladding technology in the repair of critical power plant components

Laser cladding technology has extremely broad application scenarios, earning it the title of an "all-around expert" in the industrial field. It plays an irreplaceable and important role in the repair of key power station components. Core parts within power stations, such as gas turbine unit valve bodies and coal-fired unit water wall tubes, are mostly manufactured from steels like 15Cr1Mo1V and 15CrMoG. These components are often exposed to harsh working environments, making them susceptible to impact and wear, and potentially developing cracks, which pose hidden dangers to the safe operation of the units.

Taking valve bodies made of ZG15Cr1Mo1V steel as an example, due to their complex structure and uneven wall thickness, hot cracking has always been a significant hidden danger. Once a failure occurs, it directly leads to unit shutdown. Engineers at Huayan Technology have addressed this issue by applying laser cladding technology to precisely clad specialized alloy materials onto the cracks in the valve bodies. This not only successfully fills the cracks but also further enhances the strength of the valve bodies, fundamentally eliminating safety hazards and providing a solid guarantee for the safe and stable operation of the units.

Water wall tubes in boilers are frequently subjected to impact wear from dust particles, significantly affecting their service life and increasing maintenance workload and costs. After adopting laser cladding coating technology, the wear resistance of the water wall tubes is greatly improved, and their service life is significantly extended. This technological application not only reduces the number of repairs and costs but also lowers the risk of shutdowns caused by water wall tube failures, ensuring the continuous and stable operation of power station units.

With its precise repair effects and excellent coating performance, laser cladding technology provides reliable technical support for the long-term stable operation of key power station components and has become one of the core solutions in the field of power station equipment maintenance.
