In recent years, with the development of industrial robots, whether robots will replace humans has become one of the hottest topics of our time, especially with the emergence of "customized" welding robots. It's said that robot welding speed is more than twice that of manual welding! It's also said that robot welding speed is the same as manual welding because their parameters are basically the same. What is the welding speed of a robot? What are its technical parameters?
I. Robot Welding Speed
1. Robotic welding can improve production efficiency.
Six-axis welding robots offer short response times and fast movements. Welding speeds range from 50 to 160 cm/min, significantly higher than manual welding (40 to 60 cm/min). The robot operates continuously without stopping. As long as external water and electricity are available, the project can continue. High-quality six-axis robots offer stable performance and are designed for efficient use. With proper maintenance, they are expected to be trouble-free for up to 10 years. This effectively improves a company's production efficiency.
2. Robotic welding can improve product quality.
In robotic welding, given welding parameters and a specific trajectory, the robot accurately repeats the action. Welding current and other welding parameters, including voltage, welding speed, and weld elongation, play a decisive role in the welding effect. During robotic welding, the welding parameters for each weld seam are constant, minimizing the impact of human factors on welding quality. This reduces the skill requirements for operators, ensures stable welding quality, and guarantees product quality.
3. Robotic welding can shorten product modification cycles and reduce corresponding equipment investment.
Robotic welding can shorten product modification cycles and reduce corresponding equipment investment. It can automate the welding of small batches of products. The biggest difference between robots and specialized machines is that robots can adapt to the production of different workpieces.
During product updates, the robot body can redesign the corresponding tooling fixtures according to the new product, updating the product and equipment without changing or calling the corresponding program commands.
II. Technical Parameters of Welding Robot
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 maintaining the spatial orientation of the welding torch.
2. Rated load refers to the rated load that the robot end effector can withstand. The loads we refer to include the welding torch and its cable, cutting tools, air hoses, 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. Repeatability. Repeatability refers to the accuracy of the welding robot's trajectory. Repeatability is even more critical for arc welding and cutting robots. For arc welding and cutting robots, the trajectory repeatability should be less than half the diameter of the welding wire or the diameter of the cutting tool hole, typically requiring ±0.05 mm or less.
What is the welding speed of the robot? What are its technical parameters? When selecting a welding robot, it is essential to choose the appropriate technical specifications based on your workpiece. The technical parameters of a welding robot include the number of joints, rated load, welding speed, and welding function with repeatability. At 60% of its production speed, a welding robot can weld 350 angle steel flanges per day, which is five times the production efficiency of a skilled welder. Furthermore, the robot's welding quality and stability are superior to manually welded products. The welding is accurate and aesthetically pleasing, and the speed is astonishing! This project has replaced traditional manual welding operations for steel components such as ventilation duct flanges and steel brackets, significantly improving welding quality and production efficiency.
