Abstract

In the wire and arc additive manufacturing (WAAM) technology that melts and deposits metal wire materials by arc discharge, it is possible to use a wide variety of wire materials and change the composition locally. However, CuSn alloys with a high Sn content have poor ductility and are difficult to process into wires. In this study, we proposed an accumulating method in which Sn wire is fed from the outside to the molten pool when deposition process using CuSn alloy wire with a low Sn content. In this paper, the relationship between wire feed rate and actual Sn content rate was investigated. Then, tensile tests and acoustic tests were conducted. As a result, Sn content rate of the additively manufactured materials was changed by varying the Sn wire feed rate. Moreover, it was clarified that the Sn content rate influences on mechanical properties and acoustic characteristics.
