Time of Diffraction (TOFD) Testing
JANX is an experienced provider of Time of Diffraction (TOFD) testing services, including testing done in conjunction with such other Ultrasonic Testing (UT) techniques as Automated Ultrasonic Testing and Phased Array Ultrasonic Testing.
TOFD uses longitudinal sound waves as the primary wave form in a pitch-catch technique. Initially developed to monitor and size through-wall defects at in-service plants, TOFD is now one of the most trusted methods of sizing critical flaws in multiple industries ranging from oil and gas to nuclear power. We have found TOFD highly accurate in cases where the orientation of a flaw does not accurately or adequately signal responses for pulse echo or phased array examination.
We use TOFD to examine in welds and heat affected zones (HAZ). By detecting and sizing such flaws as cracks, lack of fusion, and flow-accelerated corrosion (FOC), we help customers prioritize repairs and replacements.
