The rotating part 20 is a shaft that is rotated by being spaced apart from each other on the support 10, and is composed of two first and second rotating shafts 21 and 22, and is arranged horizontally in a shape opposite to each other.

It will be natural that any one of the first and second rotational shafts 21 and 22 (the first rotational shaft 21) must be connected with a power means (servo motor, etc.) such as a motor for transmitting rotational force, which will be described later. It is obvious that through the transfer unit 30, a rotation shaft (second rotation shaft 22) that is not connected to a power means has a structure capable of accompanying rotation.

The transfer part 30 includes a first line 31 for transferring a plurality of pipe-shaped first base materials P1 in one direction, and a plurality of pipe-shaped second base materials for welding with the first base material P1 ( It consists of a second line 32 for transporting P2) in one direction.

Of course, since each of the first line 31 and the second line 32 needs to transfer the pipe-shaped first base material P1 and the second base material P2 in one direction, the first line 31 1 It is natural that the chain 33 is formed at both ends of the base material P1, and the second line 32 also has a structure in which chains 33 are formed at both ends of the second base material P2 to rotate. In the present invention, the first and second lines 31 and 32 are formed as a chain 33, but this is a part that can be changed to a different configuration according to various embodiments of the user.

That is, these first and second lines 31 and 32 are installed in the form of a closed loop on the first and second rotation shafts 21 and 22, respectively, and are provided by the first and second lines 31 and 32, respectively.

After being vertically extended, the first bent part (a) bends by wrapping the lower part of the outer periphery of the contact part (①) of the pair (①) of the first and second base materials (P1, P2) in a'U' shape from left to right, and Subsequently, it consists of a second bent part (b) that wraps and bends again in a'U' shape from right to left, and a pair (②) of the other first and second base materials (P1, P2) adjacent to it is contacted. The first and second bent portions a and b are formed in the same manner at the lower end of the outer periphery of the portion, and then vertically lowered and extended so that the other end is connected to the high frequency control panel 41. As a result, the two high-frequency welding heads 42 are continuously connected and formed continuously.

Of course, the spacing between the plurality of high-frequency welding heads 42 is, of course, the separation distance between each pair of the first and second base materials (①, ②) (or the separation distance between the first base material (P1) (or the second base material (P2))) It will be natural that the'U' shape is a U'that surrounds the lower end of the base material to minimize interference with the first and second base materials (P1, P2) when the high frequency brazing part 40 is raised or lowered. It was made to be in shape.

In addition, the high-frequency brazing unit 40 allows the high-frequency control panel 41 to be installed at the bottom, and the high-frequency control panel 41 controls the frequency in the high-frequency welding head 42 and at the same time, the high-frequency brazing unit ( The internal servomotor and hydraulic cylinder, etc., so that 40) is controlled to a preset rise and fall time and position according to the rotation speed of the first and second rotation shafts 21 and 22 or the first and second lines 31 and 32. Controlling (the completion time according to the welding time after the completion of the ascent (the rise to the welding position)), the welding conditions are set by frequency control and the rise completion time control, the welding wait is lowered -> the rise during welding (high frequency control panel (41), The high frequency welding head 42 rises) -> repeats the lowering of the welding atmosphere).

In addition, when the high-frequency brazing part 40 is raised and high-frequency welding is in progress, a filler material input unit 60 is provided to allow the filler material to be supplied to the welding parts 34 of the first and second base materials P1 and P2. It will be natural that the filler material input unit 60 is installed adjacent to the support 10, and if it is a structure capable of supplying filler material during welding, the configuration may be variously changed according to the embodiment of the user. Is of course.
