The Stud Welding process is one of the welding technologies that are applied in shipbuilding and offshore. In this context, the objective of this study is to preliminarily evaluate the thermal behavior of the SW process for fastening threaded studs used in the off-shore sector in metallic structures where there is a restriction of thermal contribution on the back of the parts. The analyses were performed using thermocouples and the infrared thermography technique to measure the maximum temperature on the back of different plate thicknesses for different stud diameters. The study verified the maximum temperature reached and the evolution of the thermal behavior on the backside of the parts welded with SW. The results of this preliminary study show that depending on the thickness of the part to be welded, even with the reduced exposure time to the higher heat of the stud welding process, heating on the back of the part can be an imminent risk to the coating material, such as paint for example.
