In this paper, the authors presented the research on laser formed construction bars made of C20 steel on the example of the T-shape. The CO₂ TRUMPF TruFlow 6000 laser was used in the research. The influence of the laser treatment parameters (the power and speed of the heat source) on the volume of the bend angle, structure and properties of the elements (hardness and tensile strength) was examined. On the basis of the results obtained from the conducted experiments, the authors suggested a way of selecting treatment parameters so that the element should meet the strength assumptions at the allowable time of its implementation.
