Circular Welding System
System Architecture
This system utilizes a high-speed Fatek PLC as the central controller, managing the synchronization between pneumatic actuators, a precision servo system, and the welding power source.
Controller: Fatek PLC (Logic and I/O handling).
Motion Control: Panasonic Servo Motor (Precise 360° rotation/wire feeding).
Human Machine Interface (HMI): Dual-HMI setup for operator control and real-time monitoring.
Actuators: Dual pneumatic jacks for torch and wire positioning.
Operational Workflow
The machine follows a strict safety and logic sequence to ensure weld consistency:
Initialization: Operator activates the start switch.
Clamping/Positioning: Two pneumatic jacks descend—one positioning the wire guide and the other positioning the welding torch.
Pre-Flow: Shielding gas is activated first to purge the welding area.
Process Start: The welding arc ignites, and the Panasonic Servo begins the feeding/rotation process.
Execution: The system performs a precise 360-degree weld cycle.
Cycle End: Upon completion, the welding arc, wire feed, and gas are deactivated in sequence (Post-flow).
Auto-Home: Jacks automatically retract to the home position for the next part loading.
