Pedestal Welder
General
Pedestal Welders will perform welds at pre-programmed locations. The material handler robot will move the part to the Pedestal Welder into the first programmed location. After the part is in position, the Pedestal Welder will close and begin performing the required weld. When completed, the weld gun will open and the material handling robot will move the part to the next location. After all welds are completed, the material handling robot will transfer the part to the next station.
Attached to the Pedestal Welders are swing arms. The swing arm allows for the attached tip dresser to move in-front of the Pedestal Welder and begin the tip dress sequence. Once the tip dress sequence is completed, the metal shavings are removed via vacuum unit.
On the 2V02 Underbody Structure Cell, there are two (2) Pedestal Welders. They are located on the following stations:
- 2V02=V01AR41XQ11
- 2V02=V01AR52XQ11
Major Components
The Pedestal Welder features the following components.
| Item | Description | Function |
|---|---|---|
| A | Electrodes | The Upper Electrode (also known as a weld tip or electrode cap) and Lower Electrode (also known as an electrode holder or electrode body). These conduct electrical current through the workpiece to generate heat and create a weld. |
| B | Power Transformer | Transforms input voltage from the power supply to step up the voltage and current required for welding. |
| C | Power, Signal, and LeanID | These are three cables. The LeanID is used to transmit signals from the weld gun to the robot controller. The Power cable connects the weld gun to the power source delivering the required current to weld. The Signal cable is used to transmit various signals between the weld gun and robot controller. |
| D | Dresser Unit | Uses blades to refurbish the welding electrode's copper tips. |
| E | Disconnect Switch | Removes power from the ABB Tip Dresser for servicing. |
