Steel pipe weld seam brazing by high frequency induction brazing equipment

Using high-frequency induction brazing equipment to anneal steel pipe welds, the main purpose is to refine the grain structure of steel pipe welds. During the welding process of steel pipes, coarse grains will inevitably appear at the welds. In the subsequent cooling process, low-carbon martensite is very likely to appear at the weld. For these defects at the weld, the annealing heat treatment of the steel pipe weld is essential and very important.

Our high-frequency induction brazing equipment is small in size, light in weight, small in floor space and easy to move. The whole set of high-frequency induction brazing equipment is a split structure of power cabinet and transformer. In addition to providing necessary power support, the power cabinet also has a built-in cooling water circulation system. The cooling water can realize internal recycling, which is more environmentally friendly.。

Steel pipe weld annealing can be divided into longitudinal straight weld annealing and butt circular weld annealing according to different welds. We can design different induction coils according to different welds to realize annealing heat treatment for them. Using the designed induction coil, the temperature of the weld seam of the steel pipe is raised rapidly by means of induction heating, and then kept for a period of time, and cooled at an appropriate speed to realize the annealing of the weld seam of the steel pipe. The heat treatment steps are simple, and the operability is strong. Ordinary workers can learn it as soon as they learn it. The parameters of heating, heat preservation and cooling can be set independently. The safety factor is high and the heat treatment effect is good.
