Sigma provides ASNT/CSWIP/PCN Level I, II, & III technicians for Shear wave (SW) Ultrasonic Testing to detect anomalies (flaws) in welds, metal pipe, vessels, and metal floor/wall sheets.

SW is a technique using angle beam ultrasonic testing to identify subsurface anomalies not found directly underneath the probe itself. Shear wave uses ultrasonic waves that are reflected to the probe from anomalies within the metal and/or weld.  SWUT is displayed as an A-scan that a technician can use to assess the integrity of the metal and/or weld.

Certified technicians are available for call-out or long-term assignments. Sigma provides turnkey Shear wave inspection and reporting complete with equipment, consumables, vehicles (mileage), and accommodations required to perform SW.
