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。
Thin steel weld (3 ~ 15mm) manual ultrasonic testing, the more difficult the more difficult. But as long as the selection of good performance of short cutting edge, high frequency, large K value of the small wafer oblique probe, digital ultrasonic testing instrument combination debugging sensitivity, as direct as possible manual detection of direct waves, the application process properly, you can achieve better results . Manual testing is economical, fast and practical non-destructive testing methods.
