| Abstract Scope |
Many previous studies proposed equations and models to estimate the heat input of FSW, but their verifications would be still insufficient. In this study, the heat input was calorimetrically measured during FSW of aluminum alloys with various welding tools having the different shapes, and effect of tool geometries on heat input was examined. The measured heat-input increased with increasing shoulder diameter, which was in good agreement with many previous works. Interestingly, the heat input strongly depended on the probe diameter and length. An attempt to correlate the heat input with the tool surface area was made, eventually showing that the heat input linearly increased with increasing “effective surface area” defined as (half of shoulder surface area + probe surface area). This result experimentally suggests that the probe dimension affected the heat input more strongly than the shoulder diameter. |
