Microstructure and Hardness Profiles of Hybrid Laser-Arc Welded Joint for UltrahighStrength Steel.
In this investigation, hybrid laser-arc welding was performed on 6-mm thick ultrahigh-strength quenched and tempered steel plates. Laser-arc welds were characterized for hardness and metallurgical properties in three defined cooling cycles. Destructive tests of the joints revealed that the joints were characterized by tensile strength similar to ...
