汉江大桥系采用日本SM53CN钢制造,该钢种焊接性差。本文通过对SM53CN钢进行的一系列焊接性试验及接头性能试验,确定了合适的焊接工艺,制造出焊接质量良好的薄壁箱形钢桥。
Han River Bridge Department of Japan SM53CN steel manufacturing, the poor weldability of the steel. In this paper, a series of weldability tests and joint performance tests on SM53CN steel have been carried out to determine the proper welding process and produce thin-walled steel box girders with good welding quality.
