How does the spiral steel pipe perform the welding operation?

Spiral steel pipe its production process is relatively simple, not only the production efficiency is relatively high, the production of low cost, so the spiral pipe in many industries have developed, then the use of spiral steel pipe, and how to carry out the welding operation. Before the use of spiral steel pipe is to use deoxidizer for deoxidation work, so that the spiral pipe in the course of the operation will reduce the number and size of debris, to know the spiral pipe is a high-frequency welding will be a certain size of the long strip The steel strip is welded directly into a steel pipe. The shape of the steel pipe can be round or square. The high frequency welding of the spiral steel pipe is based on the principle of electromagnetic induction and the eddy current thermal effect of the AC charge in the conductor, so that the edge of the weld is heated To the molten state, so that welding, not only the appearance of good, welding mechanical properties is also better.Finally, the industrial chiller agent said, spiral steel pipe cooling will form a solid butt weld.
