Overview

Investigates manufacturing parameters affecting surface quality and hardness in DSS2209 layers, suggesting improvements for WAAM processes.

Key Points

  • The aim is to understand how different wire arc additive manufacturing parameters affect the quality of single-bead deposits made from DSS2209.
  • Examined effects of wire feed speed, travel speed, oscillation patterns, frequencies, and amplitudes.
  • Used controlled variable approach for parameter analysis.
  • Analyzed geometric dimensions, microstructure, and microhardness of the deposited layers.
  • Wire feed speed of 4.5–6.5 m/min and travel speed of 5–6 mm/s optimized bead dimensions.
  • Sinusoidal and figure-eight oscillation patterns produced uniform deposits and refined microstructures.
  • Achieved microhardness of 280–290 HV with no significant defects aside from slight depression in the arc extinction zone.
