| Abstract | This study is aimed to investigate the temperature distribution in steel rods welded by friction welding. The study is conducted by experiment and FEA simulation and conditions for calculations is from 2D. The experiment is conducted using low carbon steel rods with a diameter 15 mm and 80 mm long. The temperature is measured at the distance of 3, 6 and 9 mm. The welding conditions are designed in 3 sets in order to compare. The experimental result is compared with FEA. It is found that the temperature archived from experiment is lower than that of FEA in the beginning of the welding process. However, the result from experiment is agreed very well with the FEA result after the welding process is steady. The average differences of maximum temperature between FEA and experiment from 3 sets are about 5.6%, 7.3% and 14% for group 1, 1.6%, 9.3% and 9.4% for group 2 and 0.3%, 0.4% and 0.9% for group 3 in averages. In addition it is revealed that when the friction process and friction temperature increases the temperature rise is also increased. This phenomena is similar for both FEA and experiment. This implies that the FEA model can be used to predict the temperature distribution in welding process. |
