Abstract

To increase the strength of a welded joint during electric contact welding of a filler tape, we propose to preliminarily form a helical structural element of trapezoidal cross section on the surface of the shaft to be restored. The plane problem of plastic deformation of such an element is analytically solved. The relative deformations over the cross section of the element are determined. The obtained results can be used for the restoration of worn shafts by contact welding of tapes made of alloyed and heat-resistant steels.
