Abstract |
The aim of the study is to optimize the welding parameters for laser welded thin galvanized steel sheets using a Taguchi orthogonal array. The welding parameters such as laser power, welding speed and focal point position were determined and the optimum parameter combination for the maximum tensile load of the joints were predicted. Additionally, examination of the weld cross-sections, microhardness tests and fracture zone of the selected welded joints were conducted to understand the better performance of the joints. The optimum levels of the laser power, welding speed and focal position were found to be 3000 W, 100 mm/s and 0 mm, respectively.
