The article presents the research results of thermography method used for monitoring process of friction stir welding of sheets made of AW-5083 aluminium alloy. Nowadays monitoring the temperature is used in many fields of science, including in the diagnosis of machining and joining processes such as turning, grinding, milling, welding, etc. Friction Stir Welding (FSW) – a new technology can be successfully used for butt-welding of different types of aluminium alloy sheets. FSW method can be an alternative to traditional arc welding methods i.e. MIG or TIG. The joining process was carried out on laboratory stand built on the basis of universal milling machine FWA-31. The parameters of joining AW-5083 alloy sheets chosen after optimization of the FSW process were presented. For determining temperature and its distribution in tool-workpieces contact area, noncontact infrared method was chosen. Infrared camera ThermoGear G100 produced by NEC Avio Infrared Technologies Co., Ltd. was used. The camera has two measuring ranges defined: -40-+120°C and 0-500°C. Average value of the temperature between the tool and joined metal sheets was about 380°C in case when correct parameters of welding were chosen. Controlling the temperature allow catch the moment when the material of joined sheets is plasticized (370°C ) which is best to start the linear moving of the tool and the same start of welding. The study can be the basis for the use of thermography method to monitor the process and determine the parameters of the friction stir welding for obtaining a high quality joint.
