Abstract


This study examines the impact of weld row orientation on the mechanical properties of hardfacing wear plates, which are produced by applying a wear-resistant overlay onto S355MC structural steel using the flux-cored arc welding (FCAW-S) process. The research specifically investigates the tensile performance of specimens with weld orientations of 0°, 45°, and 90°. The objective is to determine which weld orientation optimally preserves stress transfer while minimizing performance losses in high-load conditions. The results underscore the critical role of weld alignment in influencing the mechanical response of wear-resistant overlays. This insight paves the way for future research aimed at incorporating additional influencing factors, such as the thermal effects induced during welding and strategies for minimizing the heat-affected zone (HAZ).
