Abstract
When the welding torch is manually guided, the influence on the quality of the welded joint is a welder or welding operator in automatic or robotized welding. In both cases, due to negligence, ignorance, or other objective reasons, there may be deviations from symmetry or the source of heat—welding torch—or deviations of the axis groove. That is the cause of the uneven heating of the groove side, the asymmetry of the heat impact zone, and the welding seam cross-section having different mechanical, structural, and chemical properties. The asymmetry of the amount of heat input leads to problems in the formation of the welding seam and the occurrence of welding errors.Through the work, the influence of the transverse inclination of the MAG welding torch on the geometry of the root seam, represented by the proportion of the melted material of the groove edges, is analyzed.
