WELDING TORCH VIBRATOR Russian patent published in 2011 - IPC B23K9/30 

FIELD: process engineering.

SUBSTANCE: invention relates to welding torch vibrator to be incorporated with small-size welding and building-up welding automatic devices. Proposed device comprises base plate 1, motor 2 and main case 3 coupled therewith. Said main case 3 houses additional case 4 arranged therein with offset e1. Driving element 7 with welding torch 10 is arranged inside said additional case with offset e2. Offset e1 equals offset e2. Torch vibration amplitude is varied by turning additional case 4 relative to main case 3 through the angle of 0 to 2(e1+e2). Free rotation of torch 10 in bearing 6 is constricted by flexible looped cable 11.

EFFECT: higher reliability, longer life, possibility to weld in hard-to-access points.
