Calculation of the cross-sectional area of the welded joint in automatic welding and surfacing

Abstract

The results are presented of the investigation of the effect of the surfacing parameters on the penetration area and the thermal efficiency in the conditions of constant heat input in automatic deposition of a bead on a thick component. Correction coefficients used to determine by calculations the penetration area using the well-known and corrected Rykalin equation for a spot constantly acting rapidly moving heat source on the surface of a thick component are derived.
