In recent years, China's industry is experiencing the change of "robotization", especially in the field of arc welding. Welding robot will become the development of welding automation in the future. This paper will briefly introduce its application in the field of automatic production.

With the development of science and technology, the requirement of welding technology is also increasing. Automated production needs less labor, product consistency, quality improvement, more suitable for large-scale production, thus reducing the cost and efficiency of production. However, in manual welding, it is difficult to ensure long-term continuous welding operation due to the influence of technical level, fatigue degree, responsibility, physiological limit and other factors. In addition, due to the harsh welding environment, fewer and fewer people are willing to weld by hand, and fewer and fewer skilled workers. It can be said that the current welding robot has basically met the requirements of automation.

The advantages of automation products can be summarized as follows:

1. so that the welding quality is stable, and improve, make it uniform, welding current, voltage, speed, dry elongation and other welding parameters have a great impact on the welding quality. When the robot is used for welding, the welding parameters of each weld are unchanged and will not be affected by human factors, so as to reduce the welding process level, so as to ensure the welding quality. But in the process of manual welding, welding speed, dry elongation and so on change, it is difficult to ensure the consistency of the product.

2. The working environment is improved. Using robots for welding, operators only need to unload the workpiece to avoid welding arc, sparks and so on. When spot welding, workers do not need to carry heavy manual welding pliers, so it can reduce the heavy physical work of workers.

3. Improve labor productivity. The robot can work around the clock. Because of the high speed and high efficiency welding technology, the welding efficiency of the robot has been significantly improved.

4. the production cycle of the product cleaning, easy to produce. Because the robot's manufacturing time is synchronized, the manufacturing schedule is very clear.

The difference between a robot and a dedicated machine is that it can adjust the program for different products. Of course, the advantages of welding robots are far more than that, in the future development, there will be more opportunities to replace manual.
