Parametric Optimisation of Micro Plasma Welding for Wire Arc Additive Manufacturing by Response Surface Methodology

High deposition rate with minimal heat input is one of the primary emphases in wire arc additive manufacturing. This study aims to determine optimal parameters micro plasma welding for single-layer deposition. The stability a single layer crucial as it serves foundation relative layers avoid discontinuous multi-layer material. focuses on feeding speed, and pulse their interaction between response variables. Based study, regression equation three key using Box-Behnken Design surface methodology was proposed. outcome demonstrates that op-timized sample produces smooth appearance no apparent defects.
