The purpose of the experiment was to study the influence of the laser beam in pulse mode 2023 volkl revolt 104 on metallic foils in order to obtain a spot weld.The welding process was carried out using the overlap weld method, using spot welds in various quantities.The Nd - YAG BLS 720 pulsed laser was used to conduct the experiment.The impact of the number of spot welds on the value of force needed to break the sample was examined.

A number of measurements were carried out to determine the best process parameters.Butt welding and overlap welding were also performed using a continuous weld consisting of spot retro doublewide welds.Weld strength tests were performed to select the most appropriate parameters for the process under consideration.
