摘要
对焊缝超声检测国家标准GB/T 11345-2013《焊缝无损检测超声检测技术、检测等级和评定》中技术2和GB/T 29712-2013《焊缝无损检测超声检测验收等级》所适用的平底孔试块进行了设计,介绍了用此平底孔试块来设定灵敏度和制作DGS曲线的方法。
The Flat-bottom Holed Blocks were designed based on technique 2of the ultrasonic testing of welds in national standard GB/T 11345- 2013 "NDT of welds-Ultrasonic testing-Techniques,testing levels,and assessment",and GB/T 29712-2013 "NDT of welds-Ultrasonic testing-Acceptance levels".The way how to use the Side-Drilled holes blocks to set sensitivity and make DGS was introduced.
