INSTALLATION FOR WELDING OF CLOSED SEAMS WITH ALTERNATION OF RECTILINEAR AND CURVILINEAR SECTIONS Russian patent published in 2009 - IPC B23K37/04 B23K11/06 

FIELD: machine building.

SUBSTANCE: invention can be used in machine-building production chain with computer-aided production process for welding of closed seams with drive feed of welded products. Welding machine for seam welding is outfitted by two sensors of welded edges, contains immovable desk with ball bushings and copy roller. Plate with four restrictive planks for fixation on it of bottom part is implemented with guiding grooves parallel to straight-line portion of welding seam. At intersection of grooves in points of connection of radiuses of curvilinear sections of seams there are implemented cavities. Copy roller is installed with ability of movement in tracking grooves of plate by axis of welding in plane parallel to roller electrodes and it is outfitted by spring-loaded axis. Axis is connected to rod of electromagnetic valve with ability of its fixation in mentioned grooves. Immovable desk is outfitted by ball bushings and two planks for limitation against movement of welded welded edges of product. Plate is installed in contact to ball bushing of immovable desk and copy roller.

EFFECT: installation provides simplification of technology for receiving of defect-free closed seams ensured by providing of feeding of welded edges with usage of pressure and rotation by electrode wheel.
