Infrared Thermography testingduring the welding process

Metal parts assembly by welding processes requires the performance of post-fabrication inspection to ensure the integrity of the weld seams. These inspections are timeconsuming and require the completion of welding operations before being performed. Implementation of an "in-situ inspection" to adapt or stop the process during a drift of it would allow to obtain a gain in the immobilization of the parts, to improve the quality of the assemblies, and to make the welding processes more reliable. Online monitoring of many manufacturing processes is of real interest to guarantee the quality of manufactured products.
