Inspection of partly filled welds at pre-heat temperature

Inspection of your weld with the Time of Flight diffraction Technique (TOFD) while the weld is still at pre-heat temperature can avoid costly and time consuming repairs after weld completion. The benefits are extremely high for so called "golden" welds, which are on the critical path of your turnaround planning. The benefits are also high for heavy wall welding. Every hour and day you win, can be directly offset against your production profit the same time. 

Welds with a wall thickness of 20-25mm and thicker can be inspected when it is filled for 1/3. It is recommend to inspect the weld at the different completion stages. If needed, the heat treatment elements will be moved a little to the side to make room for the TOFD scanner and moved back after the inspection.
