用于奥氏体不锈钢焊缝超声检测的对比试块组
摘要：
本发明提供了一种用于奥氏体不锈钢焊缝超声检测的对比试块组，包括多个对比试块（10），每个对比试块（10）的侧面设有焊缝（12），每个对比试块（10）内含有至少一个通孔（11），通孔（11）的中心线平行于该通孔（11）所在对比试块（10）的上表面，所有通孔（11）的中心线到该通孔（11）所在对比试块（10）的上表面的距离为一等差数列。该用于奥氏体不锈钢焊缝超声检测的对比试块组可以测试奥氏体焊缝超声检测系统的检测能力，也可以用于检测前的灵敏度调节，还很小巧便于携带。
摘要（英）：

The invention provides a reference block group used for ultrasonic detection of austenitic stainless steel welding seams, which comprises a plurality of reference blocks (10), wherein welding seams (12) are formed on the side faces of each reference block (10), at least one through-hole (11) is contained in each reference block (10), the center line of each through-hole (11) is parallel to the upper surface of the corresponding reference block (10), and the distances from the center lines of all the through-holes (11) to the upper surfaces of the reference blocks (10) where the through-holes (11) are located are an arithmetic progression. The reference block group used for ultrasonic detection of the austenitic stainless steel welding seams can be used to test the detection capability of an austenitic welding seam ultrasonic detection system and can also be used to adjust the sensitivity before detection, and is smart and convenient to carry.
