First, the robot welding speed
1. Robot welding can improve production efficiency
The six-axis welding robot has a short response time and fast action. The welding speed is 50-160cm/min, which is much higher than that of manual welding (40-60cm/min). The bot does not abort during operation. As long as external hydropower conditions are secured, the project can continue. The performance of high-quality six-axis robots is stable and reasonable. Under the premise of maintenance, there is no failure within 10 years. This actually improves the productivity of the enterprise.
2. Robot welding can improve product quality
In the robot welding process, the robot repeats this action precisely as long as the welding parameters and motion track are given. Welding current and other welding parameters. The voltage welding speed and welding elongation play a decisive role in the welding effect. In the process of robot welding, the welding parameters of each weld are stable, the welding quality is less affected by human factors, which reduces the requirements for workers' operation technology, and the welding quality is stable and ensures product quality.
3. Robot welding can shorten the product transformation cycle and the corresponding equipment investment
Robotic welding can shorten the product transformation cycle and reduce the corresponding equipment investment. It enables the automation of welding of small batches of products. The biggest difference between robots and special machines is their ability to adapt to the production of different workpieces.
In the process of product update, the robot body can design the corresponding tooling and fixture from scratch according to the new product, and update the product and equipment without changing and invoking the corresponding program commands.
Second, the technical parameters of welding robots
1. Number of joints. The number of joints can also be called degrees of freedom, which is an important goal for robot flexibility. Generally speaking, the robot workspace can achieve three degrees of freedom, but welding requires not only a certain position in the space, but also the spatial posture of the welding gun.
2. The extra load refers to the extra load that the end of the robot can accept. The loads we are talking about include the welding torch and its cables, the cutting thing, the tubing and the welding tongs. With regard to cables and cooling water pipes, different welding methods require different additional loads, and different types of welding tongs have different load capacities.
3. Repeatability of positioning. Repeatability is the repeatability of the welding robot track. The repeatability of the arc welding robot and the cutting robot is more important. For arc welding and cutting robots, the track repeatability should be less than 1/2 of the diameter of the welding wire or the diameter of the cutting hole, and it is usually required to reach ±0.05mm or less.
