Distribution of Residual Stress in Wire-Arc Additively Manufactured Small-Scale Component: Single- versus Multi-Level Heat Input

Journal of manufacturing science and engineering, 2022
Accumulated heat input during layer deposition causes high residual stress in the Wire-Arc Additive Manufacturing (WAAM) components. The developed residual stress results in defects like distortion, delamination, cracks, and low fatigue life.
