随着我国制造业的迅猛发展,制造过程中的质量控制和检测手段也越来越被人所关注,无损检测是制造过程中保证焊接质量重要手段之一,其特点在于对检测对象不进行任何破坏就可准确判断焊缝缺陷位置和缺陷性质。NB/T47013.10-2010《承压设备无损检测一第10部分衍射时差法超声检测》规定,碳素钢或低合金钢、全焊透结构型式的对接接头、工件厚度在
With the rapid development of manufacturing industry in our country, more attention has been paid to the quality control and testing methods in the manufacturing process. Non-destructive testing is one of the most important means to ensure the quality of welding in the manufacturing process. Destruction can accurately determine the weld defect location and defect properties. NB / T47013.10-2010 “Nondestructive Testing of Pressure Equipment Part 10 Diffraction Time Difference Method Ultrasonic Testing” stipulates that carbon steel or low alloy steel, full penetration structural type butt joints, the thickness of the workpiece
