| description | The heat generation, contact state, material flow and friction coefficient are all intertwined during friction stir welding
(FSW) because of the fully thermomechanical coupling nature of FSW. The value of friction coefficient and the fraction
of sliding will dominate heat generation which is the driving force to make the FSW process successful. This work
detailedly clarified how to roughly estimate the fraction of sliding and friction coefficient at the tool/workpiece interface.
Results showed that friction coefficients in FSW of various materials were in a range of 0.2-0.56. The fraction of sliding
was significantly affected by friction coefficient. The fraction of sliding was in a range of about 73-88% for FSW of
Al1100-H14 alloy and about 38-65% for FSW of Al7050-T7451 alloy. Moreover, the fraction of sliding increased with
decreasing heat input. |
