SURFACING ARRANGEMENT Russian patent published in 1994 - IPC

FIELD: welding. SUBSTANCE: arrangement has solenoid with cylindrical core, and current lead with passage for guiding consumable electrode. The core has a cut section whose plane is parallel with its axis. Working end of ferromagnetic core has projection, whereas current lead is secured to the projection engaging with working end of ferromagnetic core. The ratio of the height of the projection to the height of current lead is 0.5...0.7, whereas the width of the core at the side of the working end is determined by expression 0.5D<l<0.6D, where D is the diameter of the core. The current lead is fashioned as two relatively spring-loaded contact plates. Working surfaces of the plates have projection arranged in symmetry relative to the axis of passage. The passage for guiding consumable electrode is defined by projections. EFFECT: more reliable operation, higher quality of surfaced metal. 2 cl, 3 dwg, 1 tbl
