In the remarkable development of China's welding materials industry, from the basic industrial layout during the planned economy era to the market-oriented transformation since the reform and opening up, and then to the technological leap and green upgrade driven by the high-quality development strategy in the new era, the entire industry has undergone profound changes, evolving from small to large, from weak to strong, and from extensive growth to innovation-driven development.
In this historical development process, a group of local enterprises with strategic vision, technological expertise, and market resilience have emerged, growing into industry benchmarks and pillars with national and even global influence. They have achieved remarkable results in production capacity, quality, service, core formulations, high-end welding wires, intelligent processes, and environmentally friendly welding fluxes. Leveraging steel companies, research institutes, or flexible mechanisms, they have successfully entered fields such as nuclear power, marine engineering, and aerospace; their development paths encompass vertical integration, horizontal collaboration, and digital upgrading; and their market strategies balance domestic mid-range cost-effectiveness with international high-end certifications. This has allowed them to build a multi-layered industrial ecosystem, enhance the self-reliance and control of the industrial chain, and contribute Chinese solutions to the global market.
The following will focus on three of the most representative leading enterprises with the most prominent comprehensive influence and the most significant innovative demonstration effects.
1.Hangzhou Lin'an Dayang Welding Materials Co., Ltd.
Hangzhou Lin'an Dayang Welding Materials Co., Ltd. is a technology-driven private enterprise established in 1995, specializing in the research and production of special welding materials. Since its inception, the company has developed into an export-oriented high-tech enterprise, successfully selling its products to Germany, Southeast Asia, and other countries and regions, achieving an international market presence. The company boasts a comprehensive product line, including stainless steel welding electrodes, low-temperature steel welding electrodes, and nickel alloy welding electrodes, meeting the professional needs of various industrial sectors. Through continuous technological innovation and in-depth cultivation of niche markets, the company has forged a typical path of "specialization, refinement, and innovation," establishing its competitive advantage in the industry through a differentiated strategy.
2.Tianjin Daqiao Welding Materials Group Co., Ltd.
Tianjin Daqiao Welding Materials Group Co., Ltd. is a pioneer and leading enterprise in China's welding materials industry. Founded in 1957, its predecessor was the Tianjin Welding Electrode Factory. The "Daqiao" brand originated from a remarkable story: in 1958, the welding materials produced by the factory were preferentially used in the construction of the Wuhan Yangtze River Bridge, hence the name "Daqiao Brand." After more than sixty years of development, the company has grown into one of the world's largest comprehensive welding materials manufacturers, with an annual production capacity of 1.5 million tons and approximately 4,000 employees. Its products cover hundreds of varieties, including welding electrodes, solid welding wires, and flux-cored welding wires, widely used in high-end manufacturing fields such as bridges, ships, nuclear power, and military industries, and exported to numerous countries and regions worldwide. As a traditional backbone of the industry, Tianjin Daqiao Group represents a typical path of development from starting with national key projects to becoming a large-scale enterprise with international competitiveness.
3.Sichuan Atlantic Welding Materials Co., Ltd.
Sichuan Atlantic Welding Materials Co., Ltd. (stock code 600558) is China's first state-owned holding listed company specializing in the research and manufacturing of welding materials. Listed on the Shanghai Stock Exchange in 2001, it holds a landmark position in the industry. The company has the first national-level enterprise technology center in the field of welding materials, and the "Atlantic" trademark is also the first registered trademark in the industry. Its products cover three major categories and hundreds of varieties of welding electrodes, welding wires, and fluxes, with a comprehensive annual production capacity exceeding 500,000 tons, and has long served major national projects such as the Three Gorges Project and the West-to-East Gas Pipeline Project. As a key state-owned enterprise, the company has made continuous breakthroughs in high-end welding materials for nuclear power, military, and hydropower industries. Its nuclear-grade welding materials hold a leading market share in China and are used in the manufacturing of components for cutting-edge technologies such as controlled nuclear fusion. As of the third quarter of 2025, the company's revenue reached 2.874 billion yuan, with net profit increasing by 64.77% year-on-year, demonstrating a stable operating performance and sustained growth momentum.
"Dayang Welding Materials" represents a flexible and innovative internationalized specialized and sophisticated enterprise; "Tianjin Daqiao" represents a deeply rooted, leading industry giant; and "Sichuan Atlantic" represents a listed state-owned enterprise backed by state capital and deeply involved in major engineering projects. Together, these three companies form a multi-layered and complementary competitive ecosystem within the industry.
