**Welding Robot Programming Skills**
(1) Choose an appropriate welding sequence to minimize deformation and reduce the travel distance of the torch. This helps in optimizing the overall welding process and improving efficiency.
(2) Ensure smooth, safe, and short movement paths for the welding gun during spatial transitions. This is essential for maintaining precision and avoiding collisions with surrounding objects.
(3) Optimize welding parameters by conducting trial welds and evaluating the results. This process helps in determining the best settings for achieving high-quality welds consistently.
(4) Set up the positioner, welding gun orientation, and relative position to the joint correctly. After fixing the workpiece on the positioner, continuously adjust the positioner and robot axes to ensure that each weld is in a horizontal position. This requires careful observation and experience from the programmer.
(5) Insert cleaning programs at regular intervals during the welding process. This prevents spatter from clogging the nozzle and contact tip, ensuring proper cleaning, extending nozzle life, and reliable arc ignition.
(6) The programming process is iterative. It involves continuous checking, modification, and adjustment of the program during robot welding, including fine-tuning of welding parameters and gun posture to achieve optimal performance.
**Yaskawa Welding Robot Programming – Startup Procedure**
1. Turn on the power switch on the control cabinet to the "ON" position.
2. Switch the operation mode to “TEACH†or “Teaching Mode.â€
**Second, Editing the Welding Program**
1. Enter the program editing mode:
1.1. Navigate to the main menu and select [Program].
1.2. Choose [New Program] from the menu.
1.3. On the new program screen, press the [Select] button.
1.4. Enter the program name, such as “TEST.â€
1.5. Use the cursor to select each letter (T, E, S, T).
1.6. Press [Enter] to confirm the program name.
1.7. Confirm the program entry by selecting “Execute.†The initial program will display “NOP†and “END.â€
2. Edit the robot's trajectory (e.g., for straight seam welding):
2.1. Hold the safety switch and turn on the servo power to enter the actionable state.
2.2. Move the robot to the starting position using the axis operation keys.
2.3. Press the [Interpolation Mode] key to set it to joint interpolation (e.g., MOVJ VJ=0.78).
2.4. Place the cursor at the line number (e.g., 00000) and press [Select].
2.5. Adjust the speed using the [Convert] and arrow keys. For example, setting it to 50% would show “MOVJ VJ=50%.â€
2.6. Press [Enter] to move to the next program line (e.g., 0001).
**Difference Between Teaching Programming and Offline Programming**
Most offline programming systems for welding robots operate in a 3D graphical environment, offering a user-friendly interface. Using the “virtual teaching†method, users can click on the weld location in a 3D model to get the coordinates of the weld path.
In some systems, the weld bead can be directly generated from a pre-defined position in a graphic file, allowing the robot program to be automatically created and downloaded to the control system. This significantly improves programming efficiency and reduces the workload on the programmer.
Traditional teaching programming involves manually entering key points along the weld path, and the robot can then track the actual weld using its visual sensor. While this still involves some manual input, it reduces the effort compared to full manual programming.
However, for certain applications like arc welding, visual sensors may not work effectively for all types of welds. In such cases, full offline programming is necessary, where the program and trajectory are developed and tested on a computer without involving the robot itself.
Early offline programming software was often text-based, requiring programmers to be familiar with the robot’s command language and coordinate systems. Despite these challenges, modern tools have made the process much more accessible and efficient.
**Common Issues and Solutions in Welding Robot Applications**
(1) Weld misalignment: This could be due to incorrect weld position or issues with the torch tracking. Check the TCP (torch center point) accuracy and recalibrate if needed. If the issue persists, check and recalibrate the robot’s joint zero positions.
(2) Undercutting: This may result from improper welding parameters, incorrect gun angle, or position. Adjust the parameters and gun orientation accordingly.
(3) Porosity: Poor gas shielding, thick primer on the workpiece, or damp shielding gas can cause porosity. Improve gas flow, clean the workpiece, and ensure the shielding gas is dry.
(4) Excessive spatter: Incorrect welding parameters, improper gas mixture, or excessive wire extension can lead to spatter. Adjust the machine power, gas mix ratio, and torch positioning to reduce spatter.
(5) Crater formation at the end of the weld: Add a crater-filling function in the program to prevent this issue.
