On the morning of August 15th, a delegation from Indonesia visited the Greenstone-tech production base in Chengdu for an in-depth field investigation. The visit focused on the research and industrial application of Laserauftragschweißen and other additive manufacturing technologies. Both parties engaged in detailed discussions on key topics such as process innovation, equipment application, and material adaptability, laying a solid foundation for future technical collaborations. The delegation expressed great interest in Laserauftragschweißen technology and was eager to explore its potential applications in real industrial scenarios.

At the production facility, the Greenstone-tech technical team thoroughly explained the core logic behind Laserauftragschweißen. This process utilizes a high-energy density laser beam to rapidly melt alloy powders and fuse them with the substrate surface. It not only refurbishes old parts but also directly forms high-performance components. The applications of Laserauftragschweißen are vast, ranging from turbine blade repairs in aerospace, shaft component reinforcement in energy equipment, to gear wear treatment in heavy machinery. The delegation engaged in enthusiastic discussions with the engineers on topics such as “how to match process parameters with complex curved surfaces” and “how to break through micron-level precision limitations in forming,” with a particular focus on the reliability of Laserauftragschweißen under extreme conditions.

Der Laserauftragschweißen equipment independently developed by Greenstone-tech was the highlight of the visit. This equipment excels not only due to its integration of academic and industrial collaboration but also because of its superior adaptability to various industrial scenarios. Whether the workpiece is a millimeter-level precision shaft or a several-meter-long heavy-duty gear, or even a component with complex shapes like curved surfaces, porous structures, or irregular shapes, the equipment can achieve precise Laserauftragschweißen through intelligent programming and a flexible optical system. For example, during the restoration of gear tooth surface wear, the equipment can apply powder evenly along the curved surface contour, and for small shaft corrosion defects, it can perform micron-level repairs through a microscopic optical path, meeting the personalized needs of multiple industries and scenarios. The customer delegation highly praised the flexibility and precision of the Laserauftragschweißen equipment during the on-site demonstration.

This groundbreaking Laserauftragschweißen equipment was the result of deep collaboration between the materials team at Northwestern Polytechnical University, the mechanical design team at Xi’an Jiaotong University, and the optical research team at Greenstone-tech. The materials team from Northwestern Polytechnical University provided alloy composition design and molten pool metallurgical mechanism support, establishing a strong metallurgical bond between the coating and substrate; the mechanical design team at Xi’an Jiaotong University led the structural optimization of the equipment, achieving high-precision and high-stability control of the motion system, ensuring the accuracy of the Laserauftragschweißen process; and the optical research team at Greenstone-tech overcame the challenges of optical path integration, ensuring uniform laser energy output and real-time monitoring. During the demonstration, the equipment’s ability to “precisely repair” and “rapidly form” complex parts was clearly displayed, allowing customers to truly appreciate how Laserauftragschweißen technology enhances both production efficiency and quality, vividly illustrating the power of innovation driven by industry-academia collaboration.

The innovative development of multi-alloy powder materials also sparked intense discussions among the customer delegation. Greenstone-tech has meticulously developed a series of powders, including nickel-based (high-temperature wear-resistant), iron-based (cost-adapted), and cobalt-based (for highly corrosive environments) materials. These powders are specially optimized for the Laserauftragschweißen process and possess excellent properties such as high strength, wear resistance, and corrosion resistance. The samples of gears and shafts formed using Laserauftragschweißen exhibited dense microstructures and superior mechanical properties, fully demonstrating the material’s value in upgrading the performance of “old components.” After reviewing the data, the customer delegation was amazed by the technical specification that “the lifespan of repaired parts exceeds that of new ones by 30%” and unanimously agreed that Laserauftragschweißen holds vast potential in the field of industrial remanufacturing.

This visit by the Indonesian delegation not only provided a comprehensive showcase of Greenstone-tech’s additive manufacturing capabilities but also marks a key starting point for exporting “Made in China” solutions to overseas markets. In the future, both parties will continue to deepen the application of Laserauftragschweißen and other additive manufacturing technologies in industrial scenarios through technological collaboration, driving more innovation to empower the global industrial upgrading process. Through this exchange, Greenstone-tech will further optimize Laserauftragschweißen processes, expand its application scope in international markets, and offer more efficient and reliable solutions for global customers.
