Station type SL-2/1x200ST for seam welding of a base cup to the shock absorber cylinder


The presented station is used for semiautomatic seam welding of a detail consisting of the bottom pressed into the pipe. A welding transformer TECNA 200 kVA (P = 50%) was installed inside the body of the device. The welding process is carried out by means of two welding modules, each of which consists of a TECNA welding cylinder with a pressure of 736 daN and a welding head with a 24 kA short-circuit current, driven by a servo motor. A RFID system was used to identify the tooling and automatically recall the assigned welding parameters. It is possible to start the device after identifying the operator with the card and obtaining the assigned level of access to the device. At the Customer's request, the device uses solutions that allow to perform additional precise process measurements, including the actual electrode force and actuator path along with the diagrams. In addition, the device is equipped with an automatic regeneration system for disk electrodes with diameter control and a central lubrication system. The master PLC system from Siemens is used to control the device. In the front of the device there is a SIMATIC HMI operator panel and TECNA welding parameters controller. An MIYACHI meter was used for extended measurement of the process parameters.
