Induction welding of tubes and profiles is based on the generation of high temperature at the point of joining of metal sheets from which a profile is formed. The sheet, from which the profile is formed, is initially formed by a system of driven rolls. After reaching the desired shape, it is introduced into the induction heater inductor.

Eddy currents are induced in the part of the pipe that passes through the inductor at the point where the two ends of the profile meet, causing high temperatures and thus the formation of a weld. An automatic profile feed ensures a constant and uniform welding process.
