Sigma provides ASNT/CSWIP/PCN Level I, II, & III technicians for Digital Radiography (X-ray) to detect defects and assess weld quality.

Digital Radiography is a form of X-ray imaging, where digital X-ray sensors (plates) are used instead of silver halide based photographic films. Advantages include (1) time saving because of no chemical processing, (2) the ability to digitally transfer/enhance images, and (3) long-term storage/archival.

Instead of film, digital radiography uses a digital image capture device (plate). This gives advantages of immediate image preview and availability; elimination of costly film processing steps; a wider dynamic range for over- and under-exposure; and the ability to apply special image processing techniques that enhance the overall image display.

Certified professionals are available for call-out or long-term assignments. Sigma provides turnkey Digital Radiographic inspection and reporting services complete with equipment, consumables, vehicles (mileage), and accommodations required to perform Radiography.
