摘要：
Dimensional deformations of a steel beam after MAG welding ere analytically calculated as well as verified by experiment results. There are the key factors defined, which have an effect on the value of deformation as well as solutions offered for regulation of the value of deformation in dependence on the welding technology and by selection of the regime. Experimental studies have shown that in the researched plate by using of indirect bending in breaking jig on the calculated bending angle the deformation of the plate is reduced by 60 %; as a result the flatness after welding corresponds to the tolerance of +/- 4mm.
