Welding is an extremely crucial part of fabrication processes in the automobile, shipping, railroad and transportation, aviation, construction industries and many more. Welding defects can compromise the stability of a welded structure. In order to detect and subsequently avoid such flaws, there are various testing methods available. The Time of Flight Diffraction (TOFD) technique is widely used as the most reliable inspection method during the construction of process equipment and piping.
TOFD is a high-performance non-destructive testing (NDT) technique, which can be used to accurately detect and size cracks, slag, fusion faults and other defects in a welded construction. Our specialists can accompany you throughout your testing project and offer you individual solutions according to your requirements. Our services include weld testing using the TOFD technique and data processing with our in-house developed software. Recognized internationally with defined codes and standards, TOFD is an excellent and widely accepted pre-service and in-service inspection tool.
Our experts have extensive experience in TOFD based weld testing. We can provide you with a one-stop-shop-solution for weld testing. By using our TOFD inspection service, you will be able to save time over the duration of new build and replacement projects.

There are multiple benefits of our TOFD measurement service including a higher probability of detection compared to conventional radiographic and ultrasonic testing. Importantly, on-site inspections can be conducted in parallel to normal production in part due there being no significant logistical difficulties unlike for radiographic testing, thereby reducing costs. As the method is also less sensitive to sample thickness compared to radiographic-based methods, it provides comparatively quicker results. Inspections can also be carried out at temperatures of 400°C and higher.
Our documentation, clear data presentation and digital storage using the ScanPlan® software come together in the convenience of a one-stop based solution. Our experts are qualified in accordance with the TOFD certification program based on ISO 9721. Combined, these provide a safety standard record which benefits our customers by reducing their company liability risks.
We are committed to work with the optimum and most accurate method of non-destructive weld testing. The principle of a TOFD inspection can be described with the following steps:
Over the past quarter of a century, we have been a pioneer in the field of weld inspection and collected extensive experience. Our TOFD inspection services provide a higher probability of defect detection compared to conventional procedures such as radiographic testing (RT) and ultrasonic testing (UT). This method not only reduces costs, as TOFD inspections can take place on-site alongside continuing production work, but can also provide quick and accurate inspection data in an easily understood format. Our inspections are conducted by certified inspectors. Our proficient team members are there for you, thereby ensuring a credible and quality service.
