The purpose of the experiment was to study the influence of the laser beam in pulse mode 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. https://www.marcelovicente.com/product-category/9-12-9bv/
