A research study was done in SAMK’s machine and production technology’s laboratory, in which the goal was to see if a welding seam could be done in realtime with a thermal imaging camera. Welding technologies that were used were; MIG-, TIG- and Synergiv MAG-welding. A thermal imaging camera used was FLIR […]

Central cores are manufactured with a method called hotbox. Hotbox method means that a sand mixture is blasted into a warmed up central core box. The central core is dried out in a box where heat is transferred through heat plates on the sides and also from the bottom with the […]
Near infrared imaging has a special capability to see some materials differently than human eye or cameras working in visible light wavelengths. Let’s study imaging of two glass bottles with some water in one bottle and some kerosene based liquid in the other one. When these bottles are imaged with […]
In infrared imaging it is important to understand that different types of materials affect the temperature value that the thermal camera puts out. For example, if objects of the same material, same temperature give very different temperature results, depending on if the other is glossy and the other is dirty […]
