The Advantages of Welding Robots in Automated Production

From the birth of the robot to the present, the most commonly used is in the field of welding. According to statistics, by the end of 2007, the total installed number of welding manipulators in service around the world was close to 40,000. Welding manipulator manufacturer believes that as advanced welding equipment, its application has been vigorously promoted, and it is an important sign that China's welding industry has entered the automation era. With the advancement of science and technology, people's requirements for welding quality are getting higher and higher. Automated production requires reducing manpower, improving product consistency, improving product quality, is more suitable for mass production, reducing production costs, and increasing production efficiency. When manual welding is affected by objective and subjective factors such as technical level, fatigue, responsibility, and physiological limits, it is difficult to maintain the stability and consistency of the welding work for a long time.

Welding Manipulator

Moreover, due to the poor working conditions of welding, fewer people are willing to engage in manual welding, and there is a trend of a shortage of skilled workers. It can be said that the welding manipulator largely meets the requirements of welding automation. The advantages of automated production can be summarized as follows:

(1) Stability and improvement of welding quality to ensure its uniformity. Welding parameters such as welding current, voltage, welding speed and dry elongation have a decisive effect on the welding result. When using robotic welding, the welding parameters of each weld are constant, and the quality of the weld is less affected by human factors, which reduces the requirements for workers' operating techniques, so the welding quality is stable. In manual welding, the welding speed and dry elongation are all changed, and it is difficult to achieve uniform quality.

(2) Improved working conditions. With robotic welding, workers only need to load and unload the workpiece, which is far away from welding arc light, fog and splash. For spot welding, workers do not need to carry heavy manual welding tongs, which frees workers from high-intensity manual labor.

(3) Improve labor productivity. The robot can produce continuously for 24h. With the application of high-speed and high-efficiency welding technology, the use of robotic welding improves efficiency even more.

(4) The product cycle is clear, and it is easy to control the product output. The production cycle of the robot is the same, so the production plan is very clear.

(5) Shorten the period of product modification and replacement, and reduce the corresponding equipment investment. It can realize the welding automation of small-batch products. The biggest difference between the manipulator and the special machine is that the program can be modified to adapt to the production of different workpieces.
