Overcoming these challenges requires proper training, adequate planning, and the right steps to ensure successful robotic welding programming. Let’s understand these steps in detail.
Steps to Get Started With Robotic Welding Programming
It is easy to be overwhelmed by robot welding programming. But you can simplify the process by breaking it down into smaller steps:
1. Understand the basics
Don’t dive head-first into programming. Your first step should be to understand the basic principles of welding and robotics. Familiarize yourself with welding techniques such as TIG, MIG, and arc welding. Understand how robots are used in these applications. Concepts such as control systems, dynamics, and programming languages will provide a solid foundation.
2. Get the right training
Robot manufacturers offer training programs to master their robots. Enrolling in these programs is highly beneficial, as they cover specific programming techniques, how to use the robot interface, and best practices for maintenance and troubleshooting. You can know the ins and outs of your specific machine when you attend training from the manufacturer. This makes the transition to automated welding easier and efficient.
3. Set up your workspace
A neat, clean, and safe work environment is critical. Ensure your welding area is free of clutter and hazards. Provide adequate ventilation for smoke control and install impact barriers to protect operators from welding pressure and robot contact. Organize your office so that you have easy access to all the tools and supplies needed to run the business smoothly.
4. Calibrate your equipment
Calibration ensures precision in your welding operations. Accurately calibrate the robot, welding torch, and power source. For high-quality welds, the parameters must be set correctly, the robot motion must complement the welding process, and all equipment must operate within tolerances.
5. Start with simple programs
Starting with small programs will help you understand the capabilities and limitations of the robot and yourself. Start with simple tasks like linear welds. Experiment with different parameters and learn how they affect weld quality. And then gradually move to more complex tasks as you gain confidence.
6. Test and Refine
Perform basic operations on test items to detect potential problems. Testing allows you to observe how the robot performs in real-world situations. Monitor weld quality and make necessary modifications. Adjust parameter settings as needed to improve performance. Experimentation and refinement are ongoing processes that help you achieve the best results.
7. Document Everything
Maintain detailed records of everything you do, including your plans, procedures, and changes. There will be times you wish you had a report with you. It can be invaluable for solving problems, maintaining consistency, and training new employees. Record the specifics of each weld procedure, including parameters such as speed, angle, and number of passes. This information will help recreate successful programs and avoid repeated errors.
These steps will help you establish a strong foundation in welding robot programming. This method not only simplifies the learning process but also ensures that you get a consistent, high-quality weld.
4 Things to Take Note When Programming Welding Robots
There are specific system parameters you need to focus on to achieve top-notch weld quality. Here are four important considerations while programming welding robots:
1. Angle of attack
The angle at which the welding torch approaches the joint is important. For example, in a filet weld, the angle determines the exact amount of heat applied to the joint. A poor angle can cause poor heat distribution, resulting in a poor or incomplete weld. Proper placement of the face allows the weld to penetrate and blend well into the joint, creating a stronger and more durable bond.
2. Workpiece Offset
There is an offset between the welding torch and the work surface. This is critical to achieve proper weld penetration and bead size. Too much offset can cause poor weld material that doesn’t penetrate properly, and too little can cause excessive wetting and uneven welding. By properly adjusting the offset, you can achieve a consistent weld bead that meets the required strength and aesthetics.
3. Number of passes
The number of passes refers to the weld metal used at the joint. Elevated approaches generally result in strong welds, which are important for joints that carry high loads or stresses. Too many passes, however, will increase the risk of error and prolong the welding process. Balancing the number of passes provides adequate efficiency without loss of performance. Each pass must be carefully planned to ensure proper fusion and avoid defects such as porosity or inclusions.
4. Speed
The speed of the robot during welding affects the overall heat generation and welding quality. Fast speeds can cause insufficient heating, resulting in poor fusion and poor weld quality. And slower speeds can generate overheating, which can lead to work jamming or failure. Finding the optimal speed ensures that the weld penetrates properly without thermal damage to the product. This balance is key to producing high-quality and reliable welds.
By paying attention to these details, you improve the reliability of your welds and the overall productivity of your welding operations.
Essential Robotic Welding Tools
The right tools in place are essential to get high-quality welds and efficient workmanship. Here are 3 essential tools for successful robotic welding.
Welding Torch
The welding torch is used for applying heat to the joint. Its design and maintenance are critical for consistent operation. The torch alignment tools ensure that the lighting is positioned correctly relative to the work. Cleaning and inspecting the lamp regularly is crucial for maintaining proper gas flow. When choosing the right torch for your specific welding application consider factors like material type and size to improve your weld outcome. Additionally, ensure the torch mount is compatible with the robot's dimensions. Another thing to note is to keep the end effector with robot arm in a comfortable position to reduce issues of reachability and singularity.
Power Source
Choose a power source that is compatible with your welding robot and specific welding system. Make sure the power source doesn't fluctuate and is capable of meeting the demands of your welding project. Adjust the voltage and current settings to suit the material and desired weld facets. Advanced processes such as pulse welding can improve weld quality by controlling heat input and reducing distortion.
Welding Robot
Welding robots execute the scheduled welding jobs. Constant calibration of the robot provides accuracy and precision in its movements. Using an easy-to-use programming interface like Augmentus can help you efficiently create and adjust welding procedures. A robot, when properly prepared, can produce a consistently good quality weld with minimal human intervention. So, remember to follow routine maintenance habits like checking for damage and ensuring that all components are working properly. This is necessary to prevent downtime and maintain proper operation.
Note: Some welding robots, like FANUC's Arc Mate series, feature a hollow wrist design where the welding cables and hoses run through the robot's body. This design prevents cables and hoses from getting snagged during welding and avoids chances for downtime.
