Abstract
Heat input is one of the main parameters describing the arc welding process, among others for the needs of strict technological documentation. However, we are hearing more and more about the need to clarify this parameter. One of the problems is determining the heat input during welding of varieties with arc pulsation. The article presents an ex- periment illustrating the influence of the pulse current frequency on selected aspects of heat supply during welding of the 321 steel with the TIG method.
