Abstract


  • This study considers the use of the gas tungsten arc (GTA) welding process in

    conjunction with ‘cold’ wire addition to give layer-wise build-up of thin walled structures,

    simulating those commonly found in aerospace applications, which may in the future be

    manufactured by additive means. Taguchi DOE and multiple regression analysis methods have

    been applied to quantitatively establish relationships between common process parameters

    including arc length, arc current, travel speed and wire feed speed and resulting weld bead

    geometries and actual metal deposition rates. Mathematical expressions for build-up height,

    thickness and surface roughness are presented and evaluated against experimental data, with

    observations related to physical phenomena.
