The paper discusses the effect of the heat input in the case of welding with solid and cored wire, respectively to the quality of the obtained joints. Formulas used for this purpose do not allow for the form of the filler, which, in the authors' opinion, has an effect on the basic parameters characterizing the welded joint. The paper presents the results of research on the geometric sizes of a joint made with a similar heat input, but using the filler in the form of, respectively, solid and cored wire. Investigations were carried out on fillet-weld joints that were subjected to macroscopic metallographic examinations. Studies have shown that the heat input given without allowing for the form of the filler does not reflect the changes that occur in the welded joint due to the thermal welding cycle.
