1.The article introduces the process and the result of test ofΦ610×12.7mm UOE welding tube X60 pipeling steel. The results indicated that the datas whatever the welding seam of the finished tube,heat affected area,or the parent metal is ac- corded with the correlative satandards.
介绍X60管线钢UOE制管试验过程及相关检验结果,试验结果表明成品管焊缝、热影响区及母材的各项指标均符合相关标准要求。收藏指正
2.The dynamic tear test was used in the evaluation of the resistance to fracture of CF60 steel in the regions of the weld. HAZ and parent metal and the lowest transition temperatures of DTE-T and S_A%-T curves were obtained for the weld from the three different regions.
采用动态撕裂试验方法评定了CF-60钢焊缝、热影响区、母材的抗断裂性能,结果表明,这3个区域中焊缝的撕裂能和断口形貌的转变温度最低。收藏指正
3.The result showed that the fracture during tension occurred at HAZ where tempering took place. The UTS decreases by 12.6% of the parent metal and increases 14.1% of the as-rolled steel. The material can be saved and the weight can be lightened due to application of the dual-phase weathering steel.
结果表明 ,拉伸时焊接接头的断裂发生在热影响区的淬火马氏体回火区 ,断裂强度比母材降低了 12 .6 % ,但仍比热轧态的提高了 14 .1% ,可以实现节约钢材、减轻重量的目的收藏指正
