摘要
对芜湖长江大桥钢梁用 1 4MnNbq钢焊接性进行了试验研究 ,并与国内外常用桥梁用钢 1 6Mnq、SM490C进行了相关对比分析 ,通过试验为 1 4MnNbq钢梁焊接工艺的制定提供依据。
The weldability of steel 14MnNbq used on the beams of Wuhu Yangtze River Bridge is studied in this paper. The correlative technical datum is compared with two bridge steels-16Mnq and SM490C. The test results provide the basis for establishing the welding procedure of 14MnNbq beams.
