Yougu Technology Wins the Third‑Place Award at Vestas’ 1st Asian Welding Competition, Empowering the Global Wind‑Power Industry with Solid Strength
On September 19, Vestas’ 1st Asian Welding Competition came to an official close. With outstanding performance in welding theories and hands‑on skills, Changzhou Yougu New Energy Technology Co., Ltd. (hereinafter referred to as “Yougu Technology”) stood out among 32 contestants from 16 Asian participating enterprises and claimed the third prize in this Asian‑region contest. This achievement serves as direct recognition of Yougu Technology’s welding expertise and demonstrates its high‑reliable quality performance in key components for global wind‑turbine units.
Vestas, the event organizer originating from Denmark, is a world‑leading player in the wind‑power industry. For Vestas, welding constitutes a core procedure in manufacturing critical wind‑turbine components, bearing a direct bearing on the safety and stability of complete turbines. Through years of dedicated efforts, Vestas has built a sound and stable welding quality‑control system, laying a solid foundation for the sustainable growth of the global wind‑power sector.
As one of Vestas’ key global partners, Yougu Technology launched in‑depth global business cooperation with Vestas as early as October 2016. To date, it has delivered nearly 14 000 sets of various precision‑welded housings covering the 2 MW, 4 MW and EnVentus platforms.
Benefiting from consistently favorable quality records and technical strengths, Yougu Technology has taken part in joint R&D and manufacturing of precision‑welded housings for Vestas V236‑15.0 MW semi‑direct‑drive turbine — the world’s most powerful single‑unit wind turbine back then — since 2019. As a flagship offshore wind‑power model, it imposes extremely stringent requirements on welding quality. All welds must undergo a full suite of NDT (Non‑Destructive Testing), including rigorous ultrasonic testing, magnetic‑particle testing and visual inspection. Thanks to persistent technical breakthroughs and strenuous efforts, mass and stable supply has been realized. The first‑pass yield rate of non‑destructive testing stays above 99%. During the pivotal transformation of global wind power from onshore to offshore, especially toward deep‑sea deployment, Yougu has delivered technical and industrial support for highly‑reliable key components.
Apart from solid competence in product technologies and craftsmanship, Yougu Technology has attained top‑tier international standards in management‑system certification with ISO 3834 certification for international welding‑quality systems. ISO 3834 is an authoritative standard formulated by the International Organization for Standardization (ISO) for fusion‑welding quality management of metallic materials. Its core lies in quality control over the full welding workflow, ranging from raw‑material procurement and process design to production inspection, so as to guarantee the reliability and safety of welded products. The acquisition of this certification marks that Yougu Technology’s welding craftsmanship has reached advanced international levels, and reinforces its “welding‑quality defense line” for continuously supplying safe and stable core wind‑turbine components.
Such robust welding‑quality assurance relies not only on systematic standards, but also on strong backing from professional teams and sophisticated hardware facilities.
Professional Teams Build Quality Barriers
Yougu Technology boasts an efficient professional welding workforce of over one hundred employees with strong core talent resources: 4 International Welding Engineers, 1 International Welding Technologist, more than 50 highly‑skilled welders, together with 1 NDT engineer and a dedicated NDT team of over 30 members. Leveraging superb expertise and precise equipment, the team conducts comprehensive and accurate verification for weld seams. Multi‑layer strict quality control consolidates the welding‑quality defense line, making the team well‑deserved guardians of welding quality.
World‑Class Equipment Ensures Accurate Inspection
Besides skilled personnel, complete inspection equipment forms another pillar for Yougu Technology’s welding‑quality assurance. The company is equipped with world‑class testing instruments including 5 ultrasonic flaw detectors, 1 phased‑array flaw detector, 5 magnetic‑particle flaw detectors and 2 laser trackers. Complementing one another, these advanced devices deliver comprehensive and precise quality‑control support for weld inspection and guarantee dependable welding quality.
Looking ahead, drawing on its mature welding‑technology system and stringent quality‑control capabilities, Yougu Technology will keep focusing on R&D and manufacturing of key components for high‑power offshore wind‑turbine units. It will provide more reliable and accurate technical and product support for the global wind‑power industry’s shift toward higher power ratings and broader application scenarios, in particular offshore wind power, and facilitate the green transformation of the global energy mix.
