METHOD, DEVICE AND PROGRAM FOR ANALYSIS OF DESTRUCTION FOR POINT-WELDED PART AND MACHINE READABLE DATA CARRIER Russian patent published in 2014 - IPC G01N3/00 

FIELD: process engineering.

SUBSTANCE: peaks of tolerable load at welded part under appropriate destruction from load destruction, moment destruction and internal destruction of welded point core are defined from at least one sheet thickness t, tensile strength TS, elongation E1 and chemical composition of said core at every point-welded steel sheet, core diameter d efficient thickness B of welded part defined via distance between adjacent welded parts, ribs or crest lines and cross-section height H. Then, in compliance with said destruction modes, tolerable load at every moment after reaching of the peak of tolerable load and defined is shift or time whereat tolerable load is zero, that is, time whereat complete destruction occurs.

EFFECT: possibility to define tolerable load before complete destruction.
