DETERMINATION METHOD OF AROUND FIELD AREA FOR WELDING WITH MELTING ELECTRODE Russian patent published in 2018 - IPC B23K9/00 

FIELD: technological processes; defectoscopy.

SUBSTANCE: invention relates to the field of welding production. Method includes measuring the welding speed and the surfacing productivity from which the cross-sectional area of the weld metal is calculated. In this case, before the welding, on the basis of the technical conditions for the base and weld materials, the content of the chemical elements is determined in them, and after welding, content of these elements is determined in the weld metal, the share of the base metal in the weld metal is calculated for each chemical element contained therein, and the average value of Ψ_OS share of involvement of the base metal in the weld metal, and the cross-sectional area F_O of penetration of the base metal is calculated by the formula F_O=Ψ_OCF_H/(1-Ψ_OC), where F_H – cross-sectional area of deposited metal, cm².

EFFECT: invention can be used to assess inequality of metal melting along length of weld, without resorting to its destruction.
