Overview of the characteristics of pipeline welding machines with reliable operation and good stability

Pipeline welding construction has gone through the development process of manual welding and automatic welding. Manual welding mainly includes cellulose electrode downward welding and low hydrogen electrode downward welding. China's steel pipe circumferential welding technology has undergone several major changes. In the 1970s, traditional welding methods and low hydrogen type welding rods were used for manual arc welding.
The manual arc welding down welding technology was promoted in the 1980s, the cellulose electrode and low hydrogen electrode down welding technology was applied in the 1990s, and the self-protection flux cored wire semi-automatic welding technology is fully promoted today. Pipeline circumferential welding is mostly carried out on site construction sites, usually in harsh working environments with high labor intensity and high technical requirements for welders.
Due to the extremely difficult welding work and the aging population, there is a shortage of senior welding technicians both domestically and internationally. The application of on-site construction pipeline welding robots can improve these problems. It can not only be used as a variety of welding techniques, but also can be quickly mass-produced, making up for the shortcomings of long welder training time and low welding quality.
The control system has two sets of control functions: manual adjustment and automatic welding. The manual adjustment function enables all preparation and adjustment actions before automatic welding, including up and down adjustment of the welding gun, left and right adjustment of the welding gun, etc. The automatic welding function realizes the automatic completion of the welding process. Each part is powered by an independent power supply, completely isolated, with high control accuracy, reliable operation, and good stability.
