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。
Blocks with side-drilled holes were designed according to technique 1of 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.
