Development of Trivex friction stir welding tool Part 1 – two-dimensional flow modelling and experimental validation
Paul A. Colegrove,Hugh Shercliff +1 more
TL;DR: In this paper, a two-dimensional pin profile was optimized to minimize the traversing force of the metal flow in friction stir welding (FSW), and two versions of a tool based on the optimised profile were developed: the plain Trivex tool and the threaded Triflute tool.
