DEVICE AND METHOD FOR LINEAR WELDING OF THIN-SHEET RIBBED PANEL Russian patent published in 2015 - IPC B23K37/04 B23K31/02 B23K26/70 B23K101/18 

FIELD: metallurgy.

SUBSTANCE: holes are made on the panel, uniformly along lines of welding while ledge-shape tenons are made on said ribs. Said ribs are placed on the panel. Said ribs are locked at this position while extending tenons are bent. The panels are fitted at table plate supports shaped to segments while ribs fit in V-like grooves of said supports. The panel is locked clamps to perform laser tack of ribs. Then, extensions of tenons are welded to perform laser welding of the ribs through panel sheet. Claimed device comprises table (1), plate (2) with supports (3) shaped to segments with grooves (4). Said clamps are composed of angle pieces (5) and clips (6). Supports (3) are provided with V-like grooves (7) with their axes aligned with lengthwise axes of welded ribs (8). Angle pieces (5) are located in grooves (4) of supports (3). Panel (9) has rectangular holes (10) aligned with ribs (8) provided with tenons (11) located opposite said holes (10).

EFFECT: production of large-size flat thin-sheet ribbed panels, simplified process and device.
