METHOD OF CONTACT SOLDERING Russian patent published in 1996 - IPC

Abstract SU 1812733 A1

FIELD: soldering, namely, contact soldering of overlapping joints that may be used in metallic structures of soft alloys. SUBSTANCE: method comprises steps of heating (upon contact soldering of overlapping joints) by electric current passing through electrode fitting having surface coatings; using as coating powdered graphite or paste containing such powder and binder; applying coating onto contact surfaces of parts being soldered and(or) electrode fitting. Such method allows to enhanced stability of soldering process. EFFECT: enhanced quality of soldered joint due to uniform electric contact in electrode-part boundary due to increased strength of electrode fitting. 2 cl
