The Blocks with Side-Drilled Holes and Their Sensitivity Setting According to Technique 1 of GB/T 11345-2013

摘要: 设计了适用于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1和GB/T 29712-2013 《焊缝无损检测超声检测验收等级》标准的横孔试块, 并介绍了用此横孔试块来设定灵敏度和制作DAC曲线的方法。

Abstract: Blocks with side-drilled holes were designed according to technique 1 of 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 hole blocks to set sensitivity and make DAC was introduced.
