Description

Designing of a novel automatic laser welding equipment for "T"-profiles is done in four parts. The four are a loading system, a vertical centering system, a welding system and an unloading system. The loading system is designed to ease the loading of the profile plates. A lift can open for the loading and close to keep the plate upright. The system also contains a centering ball screw to center the horizontal plate. The vertical centering system is introduced to place the vertical plate in the perfect position. Just before entering the third system, the welding system, the profile plates are welded manually to each other for some centimetersto ensure that nothing moves from its correct place. The welding system welds the two plates automatically with a laser beam. The welding system also has a centering ball screw for the horizontal plate. The vertical and horizontal plate are pressed on to each other to eliminate a possible gap. This pressing is done by a pressing system on the welding spot. When the whole profile is welded and rolled on the unloading system, it can be taken off by the roller bridge. Two more important things are the alignment and the levelling of all the systems. The first is done by an extra profile to put all the systems in line and the second one is done by a foot with metric thread that, with the use of bolts, can lift up the frame to the right level.
