The application of welding robots not only meets the requirements of high-quality welding but also effectively alleviates the difficulty of recruiting welders. More and more companies are beginning to introduce welding robots in large quantities. When selecting a welding robot, we need to choose appropriate technical specifications based on our workpiece. The technical parameters of a welding robot include the number of joints, rated load, welding speed, repeatability, and welding functions. A welding robot with appropriate technical specifications can accurately weld workpieces. Welding robots help improve welding efficiency, stabilize product quality, and increase the efficiency of the welding production line. What are the welding process parameters for welding robots and how are they adjusted?
1. Number of joints. The number of joints, also known as degrees of freedom, is an important indicator of a robot's flexibility. Generally, a robot's workspace can achieve three degrees of freedom, but welding requires not only reaching a specific position in space but also ensuring the spatial orientation of the welding torch.
2. Rated load refers to the rated load that the robot end can withstand. The loads we refer to include welding torches and their cables, cutting tools, gas pipes, and welding clamps for cables and cooling water pipes. Different welding methods require different rated loads, and different types of welding clamps have different load capacities.
3. Welding Speed. Speed is a crucial indicator of production efficiency. The product manual displays the achievable linear speed of the robot wrist end effector for each axis connection. The low speed required for welding affects not only the position of the welding torch but also its travel and return times.
4. Repeatability. Repeatability refers to the accuracy of the welding robot's trajectory repetition. Repeatability is even more important for arc welding and cutting robots. For arc welding and cutting robots, the trajectory repeatability should be less than 1/2 of the welding wire diameter or the cutting tool hole diameter, typically requiring ±0.05mm or less.
5. Storage Capacity. Storage capacity refers to the storage capacity of the main computer in the robot controller. This reflects the length of the teach programs the robot can store and is related to the complexity of the workpieces it can process. In other words, teaching points. It is usually represented by the coefficient that can store robot instructions, the total number of bytes stored, and the number of teach points.

Conclusion
Welding robots are becoming increasingly widely and maturely used, but whether they are suitable for the welding needs of our own products is a question we need to carefully consider before introducing welding robot equipment.
