Abstract: The invention relates to a method for induction bend forming a compression-resistant pipe (I) having a large wall thickness and a large diameter. According to said method, in an initial phase t1, an initial tangent (3) of the pipe (I) is heat-treated by pushing the initial tangent (3) through the inductor (20) without the intervention of the bending lock (31). At the end of the initial tangent (3) the advance of the pipe is stopped at a time t2, and the inductor (20) is moved along the pipe (I) counter to the advance direction while the bending lock (31) is closed on the pipe (I). In order to induce the bending process in a phase t3, the movement speed of the inductor (20) is reduced to zero and the latter is moved to its bending position. At the same time, the advance of the pipe (I) is started. In a phase t4, a pipe bend (4) is produced at a constant process advance speed of the pipe (I).
