SUBSTANCE: invention relates to metallurgy and can be used for disposal of main pipelines to be processed to hoop, mainly, rolled wire with application of mobile plant. Dismantled pipe is heated to 970-1150°C at its transfer through straight-through inductor at the rate of 30-150°C/s and cut in helical line at inductor exit. Strip blank results therefrom. Cutting is performed in cutting-off pass between two rolls their rotational axes being turned through an angle relative to the pipe lengthwise axis. Magnitude of said angle is predefined from cited equation subject to pipe radius and strip blank preset width. Then, blank is cooled in guide at the rate of 15-45°C/s to temperature of 950-860°C and fed to continuous rolling mill. Blank is rolled to rolled 5.0-12.0 mm diameter wire at 830-910°C.

SUBSTANCE: invention relates to the technology of making complex holes using a laser beam, particularly a through hole for film cooling of a turbine component. At the first step, the internal part (7) of the hole (1) is made from the surface (12) to the opposite internal surface (13) of the substrate (4) using a laser (22) located in a first angular position (1) and simultaneously making a diffuser (10) part. The diffuser (10) residue (16, 18, 28) is removed at the next second and third steps. At the second step, the angular position of the laser (22) is changed to a position (II), different from angular position (I), and the laser is moved to the angular position (II) until the lateral side (17a) of the diffuser (10) is open and part of the volume (18) of the residue (16, 18, 28) remains. At the third step the angular position of the laser is changed from the angular position (II) at the second step so as to remove said residue (18). The angle in the angular positions (I, II, III) is defined as the angle between the middle line of the laser beam (25) and the surface (12) around the film cooling hole (1).
EFFECT: using a laser in three different angular positions relative to the processed substrate significantly simplifies the making of complex holes in the substrate.
