One of the main industries of our company is to provide supporting solid welding wire, welding rod, flux-cored welding wire and submerged arc welding wire for railway locomotive manufacturing and maintenance and bridge construction. The supporting products for railway locomotives can be used for the welding of Q400NQR1, Q450NQR1, Q500NQR1 and weathering steel with similar strength levels, and the supporting products for bridge construction can be used for welding the weathering steel of Q345qENH, Q420qENH, Q460qNH, Q500qNH and Q690qENH. The supporting products cover a wide range, covering electrodes, solid welding wires, flux-cored welding wires and submerged arc welding wires of different strength grades. The supporting products not only have excellent mechanical properties, but also have excellent corrosion resistance, which can meet the technical requirements of different customers.

In order to meet the needs of users, the developed series of solid welding wires WH44-8Ⅱ, TH500-NQ-Ⅱ, TH550NQ-Ⅱ, TH600-NQ-Ⅱ, TH650-NQ-Ⅱ are argon-rich gas shielded welding wires. The developed series of weathering steel supporting solid welding wires WH50NHQ, WH55NHQ and WH60NHQ are carbon dioxide gas shielded welding wires. The matching welding materials developed for weathering steel have a weathering index greater than 6.5 and have excellent weathering performance, such as matching electrodes CJ557NHQ, CJ657NHQ, CJ857NHQ and flux-cored welding wires YCJ501NHQ, YCJ551NHQ, YCJ651NHQ, which further improves the corrosion resistance and use of the welded structure. life.

Our company's supporting welding materials for railway locomotives and bridges are widely used in the industry, such as flux-cored welding wires YCJ601Ni-QL, YCJ651Ni-QL, electrodes CJ507Q, CJ607Q, CJ657Q, solid welding wires TH500-NQ-Ⅱ, TH550NQ-Ⅱ, and submerged arc welding wires MCJH60Q, MCJH65Q, etc., are used in key domestic projects such as Zhuhai-Hong Kong-Macao Bridge, Wuhan Tianxingzhou Yangtze River Bridge and Qingshan Yangtze River Bridge.

The company has maintained long-term good cooperative relations with key customers in the industry such as China Railway Shanqiao, China Railway Baoqiao, and Wuqiao Heavy Industry. The industry becomes stronger and bigger, and contributes to the construction of railway locomotives and bridges.
