Industrial Radiography (RT) Gamma rays are used to penetrate through solid material and generate an image on either film (Traditional) or phosporus plates (Computed Radiography) to view the internals and check the soundness of the material.Read more
Dye Penetrant Inspection (PT or LPI) LPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.Read more
Certified Weld Inspectors (CWI) We have multiple CWI's to perform final weld checks, monitor welding processes, review documents and more.Read more
Ultrasonic and Phased Array Testing (UT, PAUT) In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. This includes checking internals and also thickness testing.Read more
Fire Division We travel to fire departments to check their ladders for integrity, and also check their aerials for mechanical issues, structural integrity and functionality of the ladder, and waterway testing.Read more
