After more than 40 years of continuous exploration and practice, Jinyan Laser Remanufacturing Technology Development Co., Ltd. has proved that it has become very mature in the field of maintenance technology such as main parts, hot end parts and auxiliary parts of various models of gas turbines. The pattern of foreign monopoly, the technology is in a leading position in China. It has been widely used in both military and civilian products, and has been well received by users. Jinyan Laser adheres to the rigorous work attitude, the technology of excellence, the spirit of innovation in the domestic gas turbine maintenance service, and wholeheartedly serves the majority of customers, and works hard for the development of my country's gas turbine business.

Jinyan Laser Technology The company's technology follows the research on laser and superalloy technology by the Institute of Metal Research, Chinese Academy of Sciences in 1984. Through the absorption and transformation of foreign technology, it has accumulated its own unique welding process and material research and development. In the field of welding and repairing of superalloys, it is in a leading position in China. The high temperature alloy materials currently used in gas turbines can be well repaired by welding and related heat treatment. Such as: GTD111/GTD222, IN738, IN939, GH536, GH648, K465, K438, K417/K417G, K452 and other in-service materials.
