Forming process of high frequency pipe welding machine

What is the forming process of high-frequency pipe welding machine? Be a clear person, see things clearly, high-frequency welded pipe sales know what they need, step by step towards the goal. Studying the forming process of the pipe making machine is a step in the sales of high-frequency welded pipe, and a clear selection point can be achieved.
There are two different forming methods for high-frequency pipe welding machine:
1. "Welding first, forming later", that is to say, welding into circular pipe first, and then into special-shaped pipe. Such as machine, rectangular tube, ellipse, steel window tube, etc. The advantage of this method is that in the production of several steel pipes, when the strip size is allowed to be uniform, only a group of rollers are needed to weld the round pipe, and then different sections are obtained on the frame with fixed diameter. High frequency welded pipe sales believe that this pass system is simple and easy to operate, which can greatly reduce roll processing. The disadvantage is that the load of the square tube machine frame is greater than that of the forming frame due to the serious deformation and the serious diameter of the round tube.

2. Forming before welding. The special-shaped pipe with complex section can not be obtained from the deformation of round pipe, and needs to be directly molded and welded. The advantage of direct forming is that as long as the number of forming frames meets the requirements of deformation, the shape of the product is not limited. Therefore, the sales of high-frequency welded pipes found that with the development of the products, the number of forming units of welded pipes increased continuously. From forming to finishing, the deformation load of each frame is roughly balanced. In this way, the performance of the whole welded pipe equipment can be fully developed. Its disadvantage is that the number of rolls processed is large
