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

Abstract

The results are presented of the investigations of the effect of the surfacing parameters on the penetration area and thermal efficiency in the conditions of constant heat input in automatic deposition of a bead on a thick component. The correction coefficients for calculating the penetration area using the well-known and corrected Rykalin equation for a constantly acting and rapidly moving point heat source on the surface of the thick component are determined.
