A influência da geometria da ferramenta na resistência à dobra em chapas de cobre C110 e alumínio 6060 T-5 soldadas pelo método FSW

Abstract

This work has as objective the experimental comparison between the influence of the pin and shoulder geometry of the tool used in friction stir welding (FSW) process in bending, tensile and microhardness tests. Therefore, the work was made and in partnership with Vasconcelos (2019). In the first segment, tensile and microhardness tests were performed and, in the second, the bending test. Four tool geometries were used and three test specimens from each type of geometry were used during the bending test. After the test, the twelve test speciments were produced and measured in a qualitative experimental analysis. The results show that the test spicements from plates welded by the C tool had better rates in bending, traction and microhardness tests. Keywords: bending test. FSW. Tool geometry.
