What is the typical welding speed of a welding robot? What precautions should be taken?
Enterprises using welding equipment in production aim for high efficiency and
high welding quality. Therefore, many companies seek breakthroughs in welding
speed, and the high precision of the welding equipment's trajectory control is a
reliable guarantee for high-speed welding. 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 "customization" of welding
robots. It is said that the welding speed of robots is more than twice that of
manual welding! It is also said that the welding speed of robots is the same as
that of manual welding because their parameters are basically the same. What is
the typical welding speed of a welding robot? What precautions should be
taken?
I. Robot Welding Speed
1. Using welding robots can improve production efficiency.
Six-axis welding robots have short response times and fast movements. The welding speed is 50-160 cm/min, far exceeding that of manual welding (40-60 cm/min). The robot will not stop during operation. As long as external water and electricity conditions are guaranteed, the project can continue. High-quality six-axis robots have stable performance and are easy to use. With proper maintenance, they can operate without failure for 10 years. This actually improves the company's production efficiency.
2. Robotic welding can improve product quality.
In the robotic welding process, given welding parameters and motion trajectory, the robot will accurately repeat the action. Welding current and other welding parameters, voltage, welding speed, and welding elongation play a decisive role in the welding effect. During robotic welding, the welding parameters for each weld are constant, the welding quality is less affected by human factors, reducing the requirements for worker operating skills, ensuring stable welding quality, and guaranteeing 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 special machines is that they can adapt to the production of different workpieces.
During product updates, the robot body can be redesigned with 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 Robots
1. Number of Joints. The number of joints, also known as degrees of freedom, is an important indicator of robot 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 welding torch's spatial orientation.
2. Rated load refers to the rated load that the robot's end effector can withstand. The load we're referring to includes the welding torch and its cable, cutting tools, gas 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 is the accuracy of the welding robot's trajectory. Repeatability is 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 ±0.05mm or less.
What is the robot's welding speed? What are its technical parameters? When selecting a welding robot, appropriate technical specifications must be chosen based on the workpiece. The technical parameters of a welding robot include the number of joints, rated load, welding speed, and repeatability. At 60% 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 welding quality and stability of robots surpass those of manually welded products. The welds are accurate, aesthetically pleasing, and incredibly fast! 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.
The above information introduces the typical welding speed of welding robots and some points to note. We hope this information is helpful. Items welded by welding robots have beautiful shapes, consistent welds, and extremely high production efficiency, which is unmatched by manual welding techniques. Therefore, robotic welding is increasingly used in welding production.
