Abstract The handheld laser welding process is the latest innovation in welding technology with an increasingly broad range of applications primarily due to the simplicity of the welder training, the minimal influence of the welder on joint quality, low heat input, high welding speed, and lower equipment costs. In this paper, the influence of selected welding parameters (wire feed rate and laser oscillation width) on the geometric characteristics of surface welds on low-carbon steel P235GH is presented. Additionally, based on the selected optimal parameters, a butt joint is performed by welding plates made of the same base material. The dependence of these parameters on weld metal width and weld metal reinforcement is determined. Furthermore, it is concluded that use of a higher power device would most likely be successful in a complete root penetration during butt welding. Keywords: • handheld laser welding • wire feed rate • laser oscillation width • weld metal width • weld metal reinforcement |
