ELECTRIC ARC WELDING METHOD WITH USE OF ACTIVATING MATERIAL Russian patent published in 2005 - IPC

FIELD: machine engineering, possibly welding of metallic parts assembled in any three-dimensional position.

SUBSTANCE: method comprises steps of feeding to arc burning zone belt made of material neutral relative to welded metal; applying on belt surface activating material in the form of mixture of activating flux and polymer at next relation of components, mass %: activating flux, 5 - 80; polymer, 20 -95; using PTFE as polymer; making belt of fibers of silica or kaolin.

EFFECT: enhanced efficiency of welding process, improved quality of welded seam, rational feed of activating flux and polymer to arc burning zone.
