Palpadores con zapatas integradas

Los palpadores con zapatas integradas conformes a las normas combinan un palpador y una zapata en un mismo dispositivo, y ofrecen el menor espesor para la inspección con palpadores de contacto de haces angulares. Siempre se logra un buen acoplamiento entre las interfaces del palpador y la zapata porque no es necesario agregar un acoplador entre ambas. Estos palpadores se utilizan para la inspección manual de soldaduras con ángulos de 40° a 70° simultáneamente, así como para la inspección manual de grietas por corrosión bajo tensión y en aplicaciones conformes a la AWS y DGS.

Advantages

  • Probe and wedge in the same housing
  • The lowest-profile probe-and-wedge combination for contact angle beam inspection
  • Coupling always good between probe and wedge interfaces, no need for couplant between the probe and wedge
  • Very small assembly for easy access in restricted areas
  • Inspections of 30° to 70° in steel, SW or LW
  • Easy to handle
  • Probes with an internal wedge can be specially ordered to fit a specific curvature radius.

Typical Applications

  • Manual weld inspection of 6.35 mm to 19 mm (0.25 in. to 0.75 in.) thick surfaces (butt joints, corner joints, tee joints), using 40° to 70° simultaneously
  • Manual inspection of stress-corrosion cracking
  • AWS and DGS code compliant applications
