Tianjin Electric Welding Rod Factory was founded in 1957. In 1958, the Wuhan Yangtze River Bridge used the Tianjin Welding Rod Factory welding materials, and the "big bridge brand" was born. In 1997, Tianjin Iron and Telephone Welding Rod Factory implemented a joint-stock reorganization and officially established Tianjin Bridge Welding Materials Group Co., Ltd. After more than 60 years of wind and rain and hard singing, the "big bridge" has become a beautiful business card for the international and domestic welding materials industry. The planning and construction of Tianjin Bridge Welding Materials Comprehensive Industrial Park is a major strategic choice for Daqiao Group to "plan for the long-term, adjust the structure, expand the scale, and increase the level". The industrial park is located in the Xiqing Economic Development Zone of Tianjin. The planned area of ​​the park is 1.2 million square meters, the production area is 868,000 square meters, and the total investment exceeds 2 billion yuan. The group has built production bases in Jinghai, Tianjin, Hengyang, Hunan, Yinchuan, Ningxia, Changji, Xinjiang and other places.

After several generations of efforts, the company has developed into a comprehensive enterprise focusing on the research and development and production of welding materials. Main products include: welding rods (carbon steel, low alloy steel, stainless steel, nickel and nickel alloys, surfacing, cast iron, etc.), gas protective welding solid welding wire (carbon steel, low alloy steel, stainless steel, copper and copper alloys, nickel and nickel Alloys, aluminum and aluminum alloys, etc.), flux-core welding wire (carbon steel, low alloy steel, stainless steel and self-protection, etc.), flux (carbon steel, low alloy steel and stainless steel), etc. Daqiao Group is technology-oriented and vigorously promotes enterprise technological progress and product upgrades. The group has established a scientific research partnership with well-known universities and research institutes, achieving resource sharing and complementary advantages. In 2015, the Bridge Group Technology Center was officially recognized as the "National Enterprise Technology Center"; in 2021, the Bridge Group Testing Center was recognized by the "CNAS Laboratory".
