Detectores de defectos

Sondas para la inspección de soldaduras por fricción

Las sondas de corriente de Foucault multielementos (ECA) para la inspección de soldaduras por fricción están diseñadas para detectar los defectos cerca de la superficie, con una sensibilidad definida en función de la orientación axial del defecto. Estas sondas permiten controlar los procesos típicos de soldaduras, como la falta de penetración en los materiales soldados por fricción.

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.

Probe specifications

Probe coverage: 51 mm (2 in.)
Probe resolution: 1.6 mm (0.063 in.)
Frequency range: 20 kHz to 500 kHz
Number of elements: 32
Cable length: 3 m (10 ft)
Operation mode: Transmit-receive. Orientation at about 15°.
Penetration in aluminum: About 0.25 mm
Detection capability: Axial surface cracks

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.
