With the implementation of the national grid high-voltage electrical equipment project plan, as well as the rapid development of distribution network construction and smart grid, the market scale of China’s high-voltage electrical equipment industry has grown rapidly. According to the data, from 2015 to 2019, the market of China’s high-voltage electrical appliance industry maintained a steady and rapid growth, with a compound annual growth rate of 10.7%. In order to meet the production requirements of both quality and safety of customers, modern robots take HH020 as the main body and launch the project solution of “HH020 aluminum barrel laser tracking welding”.

 
The production process of pressure vessel is rigorous and complex

The manufacturing process of pressure vessels can be roughly divided into: raw material inspection – scribing – blanking – edge processing – rolling – longitudinal seam assembly – longitudinal seam welding – welding inspection – round straightening – re inspection of size – assembly. The process flow is rigorous and complex. Among them, the aluminum pressure vessel process is more complex, which not only needs to meet the above process, but also needs to supplement the high-pressure seal detection, stress analysis and other processes.

When a pressure vessel works continuously for a long time under harsh operating conditions, the failure of a pressure vessel or even the damage of a part will often lead to the shutdown of the whole set of devices, posing a threat to property and personnel. Therefore, each process of pressure vessel production is extremely important.

The modern robot HH020 welding kit can achieve high-quality welding effect on thick welding profiles, and ensure the overall dimension and form and position tolerance of the workpiece during welding, with strong consistency and high adaptability. At the same time, considering that the customer’s aluminum barrel was manually used to repair the groove in the early stage, which led to uneven process quality and other problems, the modern robot carefully configured the laser tracking system for the customer. The system can make the welding torch maintain the optimal welding posture to weld the irregular arc workpiece with the HH020 model, and can also deal with the data error caused by the reflection of the workpiece.
