The KLN QSW 400 L is a quasi-simultaneous laser welding machine using the principle cross laser beam welding.
The quasi-simultaneous welding combines contour welding and simultaneous welding. A scanner consisting of mirror and collimation unit (optical module to create a parallel beam path) leads the focussed laser beam with high speed several times over the welding contour.
Due to this high speed all welding contour areas are almost simultaneously heated and melted. Here the irradiated part gets in contact with the melt of the other part. Then by thermal conduction also the irradiated part is melted in the welding area.
By simultaneous welding pressure on both partners the parts are pressed together and connected (welded).
The KLN QSW 400 L is a modular laser welding machine. The advantage of the modular structure is that the central laser welding machine can remain unchanged in the various welding tasks and only the housing and its frame structure must be adapted to the actual welding task.
Thus, a well-tried laser welding unit can always be used. Moreover, adaptions to other welding tasks can be easily integrated, e. g. with rotary table, tool carrier, conveyeor or sliding table.
