This paper examines methodical approaches to non-destructive testing (NDT) of thin steel T-welded joints made by ultrasound welding. The choice of the active thermography method is justified. Numerical parameters were developed for characterize the operational properties of the plate-fin heat exchanger and the results of finned panel inspection by the active thermography method. These parameters were compared and the correlation was found. The developed methodological approaches will be useful in the future for developing an NDT technique that allows detecting internal defects in welded seams which decrease breaking load and worsen the operational properties of products made by finned panels.
