Uticaj poprečnog nagiba gorionika za zavarivanje MAG na geometriju korenog šava

Abstract

When the welding torch is manually guiding, the influence on the quality of the welded joint has 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 source of heat - welding torch or deviations of the axis groove. That is the cause of unevenly heating of the groove side, the asymmetry of the heat impact zone and the welding seam cross-sectional have different mechanical, structural and chemical properties. The asymmetricity of the amount of heat input leads to problems in the formation of welding seam and the occurrence of welding errors. Through the work, is analiyzed 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.
