薄钢板焊缝(3~15mm)手工超声波检测,越薄难度越大。但只要选用性能好的短前沿、较高频率、大K值的小晶片斜探头,以数字超声检测仪器组合调试好灵敏度,尽可能以直射波手动检测,应用工艺得当,就能取得较理想效果。手动检测是经济、快捷、实用的无损检测方法。
薄鋼闆銲縫(3~15mm)手工超聲波檢測,越薄難度越大。但隻要選用性能好的短前沿、較高頻率、大K值的小晶片斜探頭,以數字超聲檢測儀器組閤調試好靈敏度,儘可能以直射波手動檢測,應用工藝得噹,就能取得較理想效果。手動檢測是經濟、快捷、實用的無損檢測方法。

For the manual ultrasonic testing of thin steel weld (3~15mm), the weld of thinner was more dififcult detected. But as long as we select the good performance small crystal chip bevel probe with short front edge, high frequency and big k values, adjust the sensitivity of digital ultrasonic testing instrument, and try our best to use direct wave, we’ll get a more satisfactory result. The manual ultrasonic testing is an economic, rapid and practical NDT method.
