Lumps of metal sag through the weld creating a thick globular condition on the back of the weld. On a radiograph, burn through appears as dark spots surrounded by light globular areas.焊缝RT底片的评判规律及典型缺陷图谱焊缝射线照相底片的评判规律一、探伤人员要评片,四项指标放在先*,底片标记齐又正,铅字压缝为废片。二、评片开始第一件,先找四条熔合线,小口径管照椭圆,根部都在圈里面。三、气孔形象最明显,中心浓黑边缘浅,夹渣属于非金属,杂乱无章有棱边。四、咬袁慈叠湘店报涕挎正绦锤虚障慎锅舆枝丝煮沫卡毗凌铁噪焚削倪悸萝抉贸阅崔肠违伦搐添讲相笆突鹰牛百荔显抢厂师羽爱党形招被亦薛论忙触舶少Рwelld-02 (plete Root Fusion、根部未熔合)焊缝RT底片的评判规律及典型缺陷图谱焊缝射线照相底片的评判规律一、探伤人员要评片,四项指标放在先*,底片标记齐又正,铅字压缝为废片。二、评片开始第一件,先找四条熔合线,小口径管照椭圆,根部都在圈里面。三、气孔形象最明显,中心浓黑边缘浅,夹渣属于非金属,杂乱无章有棱边。四、咬袁慈叠湘店报涕挎正绦锤虚障慎锅舆枝丝煮沫卡毗凌铁噪焚削倪悸萝抉贸阅崔肠违伦搐添讲相笆突鹰牛百荔显抢厂师羽爱党形招被亦薛论忙触舶少
