Comparative study of the rotating bending fatigue performance of wire arc additively manufactured hollow shafts with and without TIG pre-joining
This study investigates the effect of Tungsten Inert Gas (TIG) pre-joining on the rotating bending fatigue performance of hollow shafts fabricated by Wire Arc Additive Manufacturing (WAAM) from ER70S-6 wire deposited onto stacked CCT34 low-carbon steel substrate rings. A four-factor, five-level Response Surface Methodo...
