Shandong SZESHANG Welding Materials Co., Ltd.
Changchun Engley Automobile Industry Co., Ltd. (Yingli Automotive, stock code: 601279.SH) announced that all of its production lines have fully transitioned from ESAB aluminum welding wire to SZESHANG brand aluminum welding wire. This switch is far more than a routine supplier change — it stands as compelling evidence that domestically produced high-end welding materials have reached internationally competitive levels in technology, quality, and service.
For years, the domestic market for high-end aluminum alloy welding wire was dominated by imported brands. Since its founding in 2019, SZESHANG has remained committed to a “technology-first” strategy, investing 8% of annual sales revenue into research and development. Through deep collaborations with Beijing University of Technology and Shanghai Jiao Tong University, the company has consistently tackled critical technical challenges. After seven years of dedicated effort, SZESHANG has successfully broken the foreign monopoly and achieved domestic substitution for high-end aluminum alloy welding wire.
Today, nearly 70% of all-aluminum new energy vehicle frames in China are welded using SZESHANG brand welding wire products. The company has become the designated aluminum welding wire supplier for leading domestic automotive brands including BYD, Chery, Geely, and Changan. Yingli Automotive’s full transition to SZESHANG marks yet another major automaker's strong endorsement of the company's product quality and technical capabilities.
SZESHANG Brand ER5356 aluminum welding wire offers excellent resistance to hot cracking, stable arc characteristics, and broad material compatibility. It delivers high-quality welding for dissimilar joints between 6000-series and 5000-series aluminum alloys, significantly streamlining material management and production workflows.
In addition, SZESHANG's drum-packaged aluminum welding wire offers distinct advantages over traditional spool products: superior feeding performance, larger capacity with no splices, time and material savings, and easy storage — making it particularly well-suited for robotic automated welding applications.
From general-purpose carbon steel welding wire to ultra-low-temperature specialty wires (stable at -100°C extreme environments), and further to additive manufacturing welding wires for aerospace and 3D printing applications, SZESHANG has achieved a three-tier leap across products and application fields.
Our company is now recognized as a National High-Tech Enterprise, a Shandong Provincial “Specialized and Sophisticated” SME, and has been selected as a drafter of China's National Standard for Aluminum Welding Wire. It's products are exported to more than 60 countries and regions worldwide.
Yingli Automotive's comprehensive transition is not merely a supply chain optimization — it is a microcosm of Chinese manufacturing's journey from catching up to leading. SZESHANG Welding Materials continues to strengthen its core competitiveness through technological innovation, enabling “Made-in-China welding wire” to shine on the global stage.
