There are many auxiliary equipment in welding process. Their use can not only ensure the welding precision, but also greatly improve the production efficiency. It is important equipment for the production and manufacture of steel structure parts. The following is a brief introduction of some of the main auxiliary welding equipment.
1. Welding manipulator： It is mainly used to process the longitudinal and annular welds of cylinder steel structure parts. The system consists of a cross frame, a roller, a welding power source, and a control system. Operating machine is usually equipped with submerged arc welding and gas shielded welding power source. Other auxiliary devices, such as weld seam tracker, arc length tracker, oscillator, monitor, flux delivery and recovery, can be selected according to customer needs.
China consists of nearly a thousand manufacturers of welding manipulators, mainly concentrated in Wuxi, Jiangsu Province, Jinan, Shandong Province, and Chengdu, Sichuan Province.
2. Roller：The roller rack is mainly used with the operator, mainly welding the ring weld of the steel structure of the cylinder. In addition to welding auxiliary equipment, can also be used for polishing, lining and assembly work. The working principle is very simple. When welding the circular weld of the cylinder, the roller rack rotates with the cylinder at a uniform speed to complete the welding of the circular weld.
The roller frame has self-adjusting, adjustable, flat car type, inclinable and other forms. The self-adjusting roller rack can be adjusted according to the size of the cylinder itself, the adjustable type needs manual adjustment, screw rod adjustment, screw grading adjustment, etc.
China roller manufacturers are mainly concentrated in Wuxi, Jiangsu, Jinan and Qingdao, Shandong, Chengdu, Sichuan and Zhengzhou.
3. Positioner：Welding positioner is a special equipment for welding flanges and disc-shaped parts. It can make the workpiece rotate 360 degrees or turn over 0-90 degrees/120 degrees. It can be used with operation machine and arc welding power source, so that the workpiece can reach the ideal welding position. The rotational speed is stepless speed regulation by frequency converter, and the operation is stable. The structural form can be divided into single seat tipping, head and tail type, head and tail lifting, L rotary turn over and so on.
There are nearly a thousand manufacturers of positioners in China. The homogeneity of products is serious and the competition is fierce. Most of them have simple design and R&D capabilities, and there is not much innovation. Similarly, producers are mainly concentrated in Jiangsu Province and Shandong Province, in addition, other Sichuan and Henan also have some.
