METHOD AND DEVICE FOR WELDING FLAT PANEL NECKS TO MANIFOLD PIPES Russian patent published in 2010 - IPC B23K31/02 B23K37/04 B23P15/26 

FIELD: process engineering.

SUBSTANCE: invention relates to method and device for welding flat panels necks to manifold pipes. First, halves of all circular seams and lengthwise seam of flat panel necks collars on the tubes on both sides of manifold unit. Then manifold unit is turned through 180° for second halves of circular seams and tube lengthwise seam to be welded. Circular seams are made with seam ends overlapped, while lengthwise seams are welded with the torch crosswise oscillation. Device frame 6 accommodates two manipulators 4 and 5 fitted on driven carriages 7 and 8 to move along said frame, said manipulators being fitted with welding torches 11 with their drives 12. Receiving table 13 has crosswise travel drive, screw clamps and guides. Manipulator 4 houses rotation drive, while manipulator 5 houses spring clamping mechanism 18. Both manipulators incorporate two-prism-like grips. Welding torches 11 are arranged on guides representing toothed segments 20 jointed with rotation drives 21 and secured on carriages 22 with lengthwise travel drives 23 and thrusts 24 to limit carriage travel in feeding their welding torches to manifold pipe.

EFFECT: higher quality of welded seams, simplified operation and higher efficiency.
