Torch Integrated Inspection Services offers both in the U.K. and 
              overseas a comprehensive ultrasonic inspection service to include 
              testing heat-stressed boilers and pipework, monitoring turbines 
              and generators, measuring corrosion, testing cast, forged and rolled 
              products, and welded, soldered and bonded joints and structures.
            
Our in-house funded TOFD system is used to provide rapid inspections 
              of new and in-service welds, providing a permanent record of tests, 
              giving accurate and repeatable results capable of being used for 
              condition monitoring. The system has unique scanners which enable 
              the operator to rapidly capture data from both flat and curved surfaces. 
              The rugged modular construction ensures maximum productivity with 
              minimum maintenance requirements. Interchangeable wedges, probe 
              holders and a range of transducers, ensure inspection capabilities 
              in all cases.
            
The system software is modular in construction and provides both 
              easy to use dedicated TOFD data acquisition, image processing and 
              measurement routines, coupled with facilities for database archiving 
              and retrieval of inspection results.
            
The Grey Scale D-Scan gives a finger print image of defect type 
              and depth. The combined RF display gives defect sizing capability.
