INDIVIDUAL TRACE PATTERN OF ELECTRIC ARC REFLOWS OF CURRENT-CARRYING COPPER CONDUCTORS, MODELED ON A WELDING MACHINE
It is shown that as a result of modeling a short circuit using a welding machine on current-carrying copper conductors in the initial state without subsequent thermal exposure, an individual macroscopic and microscopic structure is fixed, which distinguishes them from current-carrying copper conductors with electric arc melting removed from fire sites. The data obtained can be used in the expert fire-technical study of material objects removed from the places of fires.
