TIP FOR MELTING ELECTRODE SURFACING IN PROTECTIVE ATMOSPHERE

摘要

The nozzle enables automatic welding-on and welding by a welding seam with the increased width. The uniformly wide weld deposit with lower depth of penetration and roughness can be achieved by oscillations of the welding wire in the plane perpendicular to the welding direction with the straight-line motion of the nozzle. The oscillations also enable better filling of arranged butt welds and bridging of defects of weld edges. The transverse oscillating moving of the wire in relation to the welding direction is achieved by eccentrically mounted left bearing /9/ and right bearing /3/ on the revolving left and right tooth gear /10/ and /2/. The bearings deflect the wire /8/ passing through the swivelling casing /7/ in the screwing /5/. The left and right tooth gear /10/ and /2/ are driven by the chief tooth gear with the not indicated drive.<IMAGE>
