- FIG. 5 (c) is a cross-sectional view taken along the line Vc-Vc of FIG. 5 (d) is a cross-sectional view taken along the line Vd-Vd of FIG.
- the processing apparatus 50 is provided on the upstream side of the portion where the supply unit 54 supplies the plating material 58 in the feeding direction D1 of the metal pipe material 20, and is welded from the inner peripheral side of the metal pipe material 20.
- a cutting portion 59 for cutting the portion 15 is further provided. In this case, after the surplus portion 15d on the inner peripheral side of the welded portion 15 is deleted by the cutting portion 59, the supply portion 54 can immediately form the plating layer 19 on the inner peripheral side surface 15b of the welded portion 15.
- the welding nozzle 60 of the welding apparatus 3 irradiates a high frequency or the like from the outer peripheral side of the metal pipe material 20 so that the abutted ends 14a, 14a of the plate material 14 meet each other at the welding point WP. (See FIG. 5 (a)) is welded.
- the position of the welding nozzle 60 is fixed in the feed direction D1.
- the welded portion 15 is not formed on the upstream side of the feed direction D1 from the welding point WP, and the welded portion 15 is formed on the downstream side of the feed direction D1 from the welding point WP.
- the welded portion 15 immediately after welding is performed at the welding point WP, the welded portion 15 has a surplus portion 15d with excess meat on the inner peripheral side (see also FIG.
- the cutting portion 59 is arranged at a position separated from the welding point WP on the downstream side in the feed direction D1.
- the cutting portion 59 is composed of a blade member or the like that projects upward from the upper end portion of the rod 52.
- the cutting portion 59 can cut the surplus portion 15d of the welded portion 15 protruding toward the inner peripheral side.
- the inner peripheral surface 15b of the welded portion 15 is formed (see also FIG. 5C).
- the injection nozzle 57 injects the plating material 58 at a position separated from the cutting portion 59 on the downstream side in the feed direction D1.
- the plating layer 19 is formed on the surface 15b after cutting (see also FIG. 5D).
- a pipe making device in which the welding device 3 is followed by the plating process by the processing device 50 and then the metal pipe material 20 is cut by the cutting device 4 has been described.
- the timing at which the processing apparatus 50 performs the plating process is not particularly limited.
- the metal pipe material 20 may be cut with the cutting device 4, and then plated with the processing device 50.
- the processing device 50 may be retrofitted to the pipe making device, and the existing pipe making device may be installed. There is a merit that the pipe making device can be used as it is.
- the supply unit 54 supplies the plating material 58 by using the injection nozzle 57.
- the supply unit 54 may include a coating roller 157 instead of the injection nozzle 57.
- FIG. 8 is a diagram showing a structure in which the coating roller 157 is applied to the processing apparatus 50 shown in FIG. 2 (a).
- a coating roller 157 is provided at the end of the rod 52.
- the coating roller 157 is a cylindrical member rotatably supported around a rotating shaft 158.
- the rotation shaft 158 is fixed to the rod 52.
- the coating roller 157 is not fixed to the rod 52. Therefore, the coating roller 157 rotates around the rotation shaft 158 at the end of the rod 52.
- a part of the outer peripheral surface 157a of the coating roller 157 is arranged at a position outside the rod 52 and close to the surface 15b on the inner peripheral side of the welded portion 15.
- the other part of the outer peripheral surface 157a of the coating roller 157 is arranged at a position in the rod 52.
- the supply pipe 56 extends in the rod 52 to a position close to the outer peripheral surface 157a of the coating roller 157.
- the supply pipe 56 can supply the plating material 58 to the outer peripheral surface 157a of the coating roller 157 in the rod 52.
- the coating roller 157 rotates.
- the plating material 58 supplied from the supply pipe 56 adheres to the inner peripheral surface 15b of the welded portion 15 as the outer peripheral surface 157a rotates.
