Assembling and welding machine for alveolate leaning pipes

The utility model provides an assembling and welding machine for alveolate leaning pipes. Both the press rack (1) and the welding rack (4) are frames formed by more than two transverse grids; compression blocks (2) are arranged on each transverse grid of the press rack (1) at regular intervals; a heating core (3) is arranged on each transverse grid of the welding rack (4) in a manner of corresponding to the ripple on a sheet; the press rack (1) and the welding rack (4) are both arranged at the upper part of a worktable (11); the welding rack (4) is positioned above the press rack (1); a sheetbracket (6) is hinged on the worktable (11) in a manner of corresponding to two ends of the sheet; a support strip chute (10) is fixed on the worktable under the sheet bracket (6); and a support strip(9) is placed above the support strip chute (10) in a manner of corresponding to the sheet. By adopting the integral-positioning and wholly-welding manners, the assembling and welding machine for alveolate leaning pipes great
