5.8. PLC automatic welding control system

This controller is the central system that completes the entire process of circumferential seam welding. It adopts a stable and reliable PLC programmable control technology platform.

In the actual production welding process, in order to complete the complex welding tasks of different products, the relevant welding parameters and motion parameters should be matched and implemented through a centralized controller. The controller adopts multi-module centralized control mode, and coordinates and communicates the relevant welding parameters and motion parameters through programming. The controller has the characteristics of simple programming, intuitive interface, convenient maintenance, strong anti-interference ability, considering that the workshop network voltage may fluctuate greatly at any time, so the system controller adopts a larger engineering control cabinet, the cabinet layout ventilation, dustproof, heat dissipation, anti-interference and other functions can achieve stable work, while easy to monitor and maintain. The input voltage of the control cabinet is 380V or 220V 50Hz ±10%, beyond this range it is recommended to increase the regulated power supply. Each functional module and switching element is reasonably installed in the controller through a trunking. A fan is installed on top of the control box to effectively dissipate heat within the chassis. There is a dust-proof partition on the edge of the box, which can effectively isolate the dust on the work site and prevent dust from entering the control box and depositing on the components and causing device failure.
