奥氏体不锈钢焊缝专用超声波试块
摘要：
本实用新型公开了一种奥氏体不锈钢焊缝超声波检测专用超声波试块，包括三块等厚度的焊缝为坡口型的焊接试块，第一块在焊缝左熔合线上，每隔一定距离钻设有横通孔，第二块在焊缝右熔合线上，每隔一定距离钻设有横通孔，第三块在焊缝中心线上，每隔一定钻设有横通孔。本实用新型可以解决奥氏体不锈钢焊缝缺陷准确定量的技术问题。
摘要（英）：

The utility model discloses a special ultrasonic wave test block for a welding seam of austenitic stainless steels. The special ultrasonic wave test block comprises three welding test blocks with the same thickness and the groove-shaped welding seam, wherein the first test block is arranged on a left fusion line of the welding seam and is provided with transverse through holes at regular intervals in the drilling manner; the second test block is arranged on a right fusion line of the welding seam and is provided with transverse through holes at regular intervals in the drilling manner; and the third test block is arranged on a central line of the welding seam and is provided with transverse through holes at regular intervals in the drilling manner. The special ultrasonic wave test block can solve the technical problem of the accurate quantification of defects of the welding seam of austenitic stainless steels.
