Web20 feb. 2007 · Cited-By (1) In friction welding, heat input is significant factor, which affects the quality of welded joints. It is difficult to calculate the heat input, because friction heating is complicated phenomenon. Therefore, there is no general calculation method in friction … WebBy using a calorimetric technique, the heat inputs generated during the friction stir welding of the aluminium alloys, 1100 and 5083, were measured over a wide range of welding parameters. An empirical equation to estimate the heat input using the welding parameters was established based on a multiple regression analysis of the results. the south shall rise again quote
