Brief Analysis of Good Technical Characteristics of Welding TINE:2019-03-18 22:22 Edit:admin
When the welding line encounters large fillet weld, it is suggested that double power supply, double wire, double arc and double molten pool welding process be adopted, and imported PLC control is used to make the whole process more reliable.
At the same position of the welding production line, the whole process of material erection, welding, orthodontics, lifting and discharging can be completed continuously in the production process, and the degree of automation is very high.
Welding roller frame, welding manipulator, welding positioner
The working mode of H-section steel welding production line is to place H-section steel in accordance with the "I" shape first, and then weld two corner seams on both sides at the same time. This will help to improve the welding efficiency. Moreover, symmetrical welding is used in the welding production line, because the workpiece will not deform after welding.
In this welding production line, there is also an orthodontic mechanism, which can directly rectify the angular deformation of hot material after butt welding by eccentric pressing roll, thus reducing the correction force and improving the correction accuracy. From the welding specifications, the welding production line can almost meet the welding requirements of different specifications.
In the group cube mode, the welding production line adopts the group-welding integration mode, which reduces the process and improves the production efficiency. And its wire feeder and welding torch soft connection and welding torch angle can be adjusted according to actual requirements, to ensure that the quantity of welding quality can be achieved.
Whether it is a welding roller rack, a welding operator or a welding positioner, it can be used as a part of the welding production line to guarantee the completion of the welding operation. At present, the H-beam welding production line is in contact with a lot of people, and its design in all aspects is quite reliable.
