| 摘 要： | 根据GB／T2358—1994标准，对16ram厚的高强船体钢焊接接头的焊缝中心-40℃的裂纹尖端张开位移（CTOD）进行测试，绝大部分试样的断裂韧性值是有效合格的，其CTOD值大于0．15mm，符合DNV验收标准。试验结果表明，在给定的双丝埋弧焊接工艺下，该钢种焊缝低温韧性好。该钢种中等厚度双丝埋弧焊焊接接头可以在不进行焊后热处理的情况下使用。

| Abstract: | According to GB/T2358-1994 standard,the crack tip opening displacement(CTOD) of 16mm thick steel 10Ni3CrMoV center seam of welded joints the crack tip opening displacement(CTOD) at temperature-40 ℃ was tested.The majority of the specimen fracture toughness values are satisfactory,with CTOD value over 0.15mm in line with the DNV standard of acceptance.The experimental results show that with given two-wire submerged arc welding process,the low temperature toughness of the steel welds is good and the joint of medium thickness steel plant with twin-wire submerged arc welded technics can be used without heat treatment after welding. |
