Laser welding machine

This customized welding device is used for aligning, joining, fixing and positioning flat or curved profiles for welding side walls of long-distance trains. Structure of the clamping and welding device The approx. 24 m long base frame is characterized by a solid and divided modular design. It consists of several segments which are screwed together. Along the longitudinal carriers there are adjustable suspension devices for mounting, lengthwise displacement and locking of the cross carriers. The device includes 10 crossbars and 7 joining units. Further components of the welding device are 4 turning devices, which are required for turning the assembly group. Limit stops and various accessories complete the device. Between the longitudinal carriers of the base frame, the base frame is equipped with gratings so that an increased working platform is created for retooling. Functions of the clamping and welding device For each sidewall type to be manufactured, there are defined positions for the joining units and crossbars. These are set at the beginning. For this purpose, labels are attached to the base frame where the respective position for the sidewall type can be read. Markings facilitate the alignment. The individual profiles are inserted, aligned and clamped into the corresponding joining units and crossbars. Then the front side is welded by the robot system. After welding the front side, the assembly group is turned by means of the turning device. Finally, the back side can also be welded.
