Using the pad welding technique it is possible to regenerate machine parts or improve surface properties such as abrasion, corrosion and aging resistance. The regeneration process with the use of pad welding can be performed using the same equipment, which we use for welding. Metals and their alloys with required properties in the form of wire, rod or powder are selected for the additional material. To ensure optimum processing conditions and economic efforts should be made, while providing a high deposition efficiency for the small amount of metal in the pad weld substrate. The pad welding process for the test subject should be carried out by preheating to evaporate the moisture and reduce the porosity of the weld. This treatment is required depending on the carbon equivalent. This article is an introduction to a series of investigations that will allow you to choose the best parameters of pad welding GMA (gas metal arc) method, steel C45E with wire CASTOMAG 4554S. Steel samples were prepared and preheated to 300°C. Using the orthogonal experiment plan, the influence of selected parameters on the geometry and depth of fusion was determined. The analysis was based on current and wire feed speed. The test was carried out for three current values: 60, 75, 90 A and wire feed rate of 1.5, 2, 2.5 m/min. The purpose of the analysis was to select appropriate technological parameters. Obtaining the smallest share of the base material in the weld pad and impact assessment parameters for welding seam geometries. For the analysis of the results of multiple regression was used.
