摘要: 介绍了在高炉用钢厚板电渣焊中应用振动调制工艺的试验,并对三种振动参数(0g
n、0.3g n和0.6g n)下焊后接头的残余应力、拉伸性能、侧弯性能和冲击性能进行了测定,试验结果充分证明了合理的振动调制工艺可以有效地降低残余应力和改善焊接接头的综合性能,特别是在0.6g n的振动下侧弯性能合格率达到了100%。 Abstract: Vibratory conditioning technology was used in the electro-slag welding of blast furnace steel and mechanical properties of welded joint were measured.The results have proved that vibratory conditioning technology can effectively improve the comprehensive properties of welded joints.Especially,at the 0.6 acceleration of gravity vibratory state,the qualification rates of side bend performance are up to 100%.
