Analysis of the Effect of Linear Oscillation Parameters on the Laser Weld Strength of DP1180 Steels Using the Taguchi Method

Abstract

This study experimentally investigated the effects of welding parameters on the mechanical performance of DP1180 advanced high-strength steel (AHSS) sheets commonly used in the automotive industry, using a laser welding method. The experiments were performed using a 5 kW fiber laser welding system equipped with a wobble-head unit capable of linear beam oscillation. Welding speed, oscillation amplitude, and oscillation frequency were selected as the primary process parameters, while laser power was kept constant at 1000 W. Parameter optimization was carried out using the Taguchi L9 orthogonal array, and the mechanical performance of the welds was assessed via tensile testing. The results showed that fracture strength was significantly affected by oscillation frequency and amplitude. Taguchi analysis identified the optimal parameters as 2.5 m/min welding speed, 0.6 mm amplitude, and 100 Hz oscillation frequency. ANOVA revealed that oscillation frequency was the dominant factor (≈45%), followed by amplitude (≈32%), whereas welding speed contributed only about 10%. The findings showed that applying linear oscillation improves weld-pool stability, promotes more uniform melting, and enhances overall weld-seam integrity.
