Typical application

Near-surface defect detection with a preferred sensitivity to axial defect orientation. This probe is designed to monitor typical weld processes such as lack of penetration in friction stir weld applications.

Technical Note

To monitor friction stir weld processes, which typically lead to defective conditions such as kissing bonds or cracking, the SAAR-051-100-032 probe is an ideal choice.
For detection of small surface-breaking defects, where high resolution is required, choose the SBBR-022-300-032 probe.
For typical maintenance applications, where direct detection of subsurface defects is required, choose the SAB-067-005-032 probe.
