Influence of MIG Process Parameters Correction on Bead on Plate Welds Geometry

This study investigates the influence of arc length correction and dynamic correction on the geometry and stability of bead-on-plate welds produced using the MIG Pulse Synergic process. S235 carbon steel was used as the base material, with Inconel 718 as the filler metal. Welds were evaluated through visual inspection, 3D scanning, and statistical analysis. Results showed that arc length correction had a significant impact on bead width, height, weld toe angle, and heat input, while dynamic correction had a more limited effect, primarily influencing process stability and bead width at extreme settings. The findings provide guidance for optimizing welding parameters to improve WAAM process.
