METHOD FOR AUTOMATIC ELECTRIC ARC FUSION OF COATING UNDER FLUX LAYER ON INNER CYLINDRICAL SURFACE OF ARTICLE

摘要

processes for electric arc flux-layer fusion at restoring worn coatings and applying strengthening coatings onto new parts. SUBSTANCE: method is realized with use of working organ in the form of shaped-rod members fixed by winding onto face of guard having cylindrical surface portion. Plane normal relative to axis of burner and including upper point of working organ is spaced by distance equal to 0.5-2 fusion strokes from arc burning zone. In order to remove slag scum, the last is moved by means of working organ from fusion zone towards portion of article had been fused. Direction of winding provided by working organ is selected opposite relative to direction of article rotation. EFFECT: enhanced quality of fused coating. 9 dwg, 1 ex
