High-frequency welded pipe is a kind of pipe that uses high-frequency current to heat the metal sheet, and then presses it into a pipe, in which special attention should be paid to the step of high-frequency welding, which is the core of the entire production process, today let's talk about the entire production process.

    1. Preparation of raw materials

Start by preparing the steel strip or plate. It is necessary to select materials of good quality and meet the requirements, and there should be no cracks, pits and other defects. Just like cooking requires choosing the right ingredients first, good raw materials can make good welded pipes.

2. Steel strip cutting

Cut the steel strip to the required length. This length should be determined according to the specifications of the welded pipe to be produced, not too long or too short.

3. Steel strip forming

The steel strip is gradually bent into a tube shape through a series of machines. It's like origami, turning a flat steel strip into a round tube. In this process, it is necessary to ensure that the edges of the steel strip are aligned and there should be no misalignment.

4. High-frequency welding

This is a crucial step. The heat generated by the high-frequency current is used to heat the edges of the steel strip to a melted state, and then they are fused together under pressure. It's like gluing two sheets of paper together, except here the steel strips are welded together at high temperatures. This process must control the current, voltage and welding speed, otherwise the welding quality will not be good.

5. Weld treatment

After welding, there may be some unevenness or welding slag at the weld seam. The weld should be treated smoothly by grinding, scraping and other methods to remove the welding slag. In this way, the appearance of the welded pipe is better-looking, and it is not easy to have quality problems.

6. Fixed path

Use a sizing machine to adjust the outer diameter of the welded pipe to the specified size. Just like making a cake with a mold to make a cake into a specific shape, the sizing machine is to make the welded pipe to the specified size.

7. Cutting

Cut the welded pipe according to the length required by the customer. It can be cut with a saw or flame.

 8. Quality inspection

Finally, the quality inspection of the welded pipe should be carried out. Check whether there are any defects in appearance, whether the dimensions are accurate, whether the weld quality is good, etc. Only welded pipes that pass the inspection can be sold from the factory.
