title = "The porosity and mechanical behavior of 2219-Al fabricated by wire and arc additive",
abstract = "In this research, four different arc modes including conventional cold metal transfer (CMT), CMT-pulse (CMT-P), CMT-Advanced(CMT-ADV) and CMT pulse advanced (CMT-PADV) were used to deposit 2219-Al wire. The effects of different arc modes on porosity, pore size distribution and mechanical properties were given a thorough analysis. A number of multilayer thin-wall parts were fabricated to verify the suitable arc mode for the fabrication of 2219-Al alloy with excellent mechanical properties. The statistical analysis of the porosity and the size distribution indicated that the CMT-PADV process gave the smallest pore area percentage, aspect ratio and had almost no larger pores. The tensile strength could reach to 280MPa for the as deposited 2219-Al samples both in horizontal and vertical directions by the CMT-PADV arc mode. In addition, large 2219-Al metal parts were fabricated by the most suitable arc mode.",
