2. Gas-Shielded Solid Wires: Approximately 50,000 tons/year, widely used in automated and high-efficiency welding.

3. TIG Wires: Approximately 1,000 tons/year, designed for precision welding processes.

4. Submerged Arc Wires and Fluxes: Approximately 25,000 tons/year, meeting the needs of large-scale components and heavy equipment manufacturing.

5. Welding Materials for Pressure Equipment: Approximately 5,000 tons/year, providing reliable solutions for high-standard applications such as pressure vessels.

These products are extensively applied in high-end manufacturing sectors, including wind power, construction machinery, high-speed railways, shipbuilding, large-scale construction, petrochemical pipelines, pressure vessels, large boilers, and offshore engineering, offering robust technical support for major national projects.

Industry Position and Honors

As a council member of the China Welding Association, the company actively participates in the formulation of industry standards. It has led or contributed to the drafting of national welding standards on multiple occasions and served as a core member of the national standard drafting working group, demonstrating its authoritative role in the industry. The company's "Shuangjiu" brand welding wire has been recognized as a high-quality brand in China's machinery industry, earning strong market trust.

Adhering to stringent international quality management standards, the company has obtained certifications for ISO 9001 Quality Management System, ISO 14001 Environmental Management System, and ISO 45001 Occupational Health and Safety Management System. Additionally, its main products have received authoritative certifications such as Japan's JIS, the EU's CE, Germany's TÜV and DB, Canada's CWB, and approvals from nine major international classification societies (e.g., ABS, DNV, LR). These certifications enable its products to be sold globally and widely used in international markets.

Technical Management and International Collaboration

In January 2005, the company appointed a Japanese welding expert as a senior technical and management consultant, fully adopting the JIS standard and implementing refined guidance across production processes. From raw material procurement to manufacturing and final inspection, every procedure strictly follows standardized operations, significantly enhancing product quality and production efficiency. Meanwhile, the company has actively recruited high-caliber management professionals to establish a scientific and efficient management system.

Through years of effort, the company has become one of the few domestic enterprises to obtain JIS certifications for both solid wires and submerged arc wires, achieving internationally leading product quality. To ensure customer confidence, the company has implemented a comprehensive product traceability system. Each product's smallest packaging unit is marked with a unique identification code, allowing full traceability to raw material sources, production batches, and entire process parameters, thereby providing transparent and reliable quality assurance.

R&D Innovation and Industry-Academia Collaboration

The company consistently regards technological innovation as the core driver of development. With a professional R&D team led by industry experts, it continuously increases R&D investment, focusing on cutting-edge technology development and new product design in welding materials. In recent years, the company has successfully launched multiple high-performance welding materials, addressing the market's urgent demand for efficient, eco-friendly, and intelligent welding processes.

To further enhance its technological competitiveness, the company has established long-term, stable industry-academia partnerships with renowned universities and top research institutions such as the Shagang Steel Research Institute. Through collaborative laboratories, technological breakthroughs, and commercialization of R&D results, the enterprise has broken through critical barriers in welding material technologies, cultivating several self-developed core technologies with independent IP rights, thereby facilitating technological progress and industrial transformation within the sector.

Future Outlook

Looking ahead, Zhangjiagang Hengchang Welding Materials Co., Ltd. will uphold its corporate philosophy of "Quality as the Foundation, Innovation as the Guide," striving to become a global leader in the welding materials industry. The company will further deepen its internationalization strategy, optimize its product portfolio, and enhance intelligent manufacturing capabilities. At the same time, it will actively respond to the era's demands for green and low-carbon development, contributing even greater strength to the high-quality advancement of China's manufacturing sector.
