摘　　要：对 CF- 62钢焊接接头 J- R阻力曲线和断裂韧性 JIC进行了测试 ,并用参数假设检验及概率纸等方法 ,对试验结果进行了分析和检验 ,得到了 JIC的分布规律和特征值 ,为高强钢焊接接头断裂韧性的测试方法提供了依据。The fracture toughness test for the welded joint (welding seam and heat affected zone) of CF 62 steel was carried out. It was shown that the fracture toughness ( J IC ) of the welded joint of CF 62 steel was well fitted for log normal distribution by combination of the goodness of fit test and probability paper methods.
