摘要： PROBLEM TO BE SOLVED: To perform cladding by welding so that a base material side is not melted though a TIG arc having a high current is used for performing overlay welding with high efficiency. SOLUTION: This is a device for cladding by welding, which performs the cladding by welding of an adding wire 10 sent from a wire torch to a base material 13 by using a TIG torch 2 and the wire torch 3. A TIG arc having an arc current of 300 A or over is generated by the TIG torch. For the tungsten electrode 4 of the TIG torch, the tip of the electrode is oscillated and moved with amplitude of 10 mm or over and a frequency of 10 Hz or over, and the TIG arc performing the cladding by welding is used by adding the above adding wire 10 having a melting point lower than that of the base material. An arc current is caused to flow to the extent that the surface of the base material is hardly melted or the moving speed of the tungsten electrode must be set to the same extent. By controlling the quantity of the arc current synchronously with the oscillating phase of the electrode to the surface of the base material, the surface of the base material is almost uniformly heated.

摘要： PROBLEM TO BE SOLVED: To miniaturize a welding head, to reduce the man-hour, to reduce defective welding, and to achieve the stable welding or the like by combining a guide ring with a U-shaped part and a half-moon part, and providing a U-shaped rotary part. SOLUTION: A torch turning gear 6 is turned so that the position in the rotational direction of a rotary part 5 is matched with the position of a guide ring 3. An arm turning gear 9 is turned so as to be slightly moved outside. A guide ring 4 is opened, and placed into a stub 2 from the opening direction. The guide ring 4 is closed, tightened to the guide ring 3 by bolts, and a welding head 100 is fixed to the stub 2. A torch 14 is positioned by the torch turning gear 6, the arm turning gear 9, and a torch elevating/lowering mechanism. The wire is fed by a wire feeding roller 10, and because the shape of conduit liners 12, 13 is unchanged during one turn of the torch 14, the wire can be fed stably, and surely fed into the molten pool.

摘要： PROBLEM TO BE SOLVED: To facilitate the winding work of a continuous body without requiring a swivel joint by providing a continuous body guiding means surrounding a fixed drum for winding the continuous body, and driving the continuous body guiding means with a driving means. SOLUTION: When a composite body 1 is extracted against a spiral spring 6, a ring 5 and a satellite reel 3 are rotated in the unwinding direction, and the composite body 1 is unwound from a fixed drum 2. A moving body is moved to the left at this time, and the composite body 1 is not restrained by a stopper 21. When the extraction of the composite body 1 is stopped, the moving body is moved to the right, and the composite body 1 is restrained by the stopper 21. When the composite body 1 is once extracted and released, the ring 5 and the reel 3 are rotated in the winding direction, and the composite body 1 is wound on the drum 2. The moving body is moved at a high speed and located on the left of a grade groove, and the composite body 1 is prevented from being restrained by the stopper 21.

摘要： PURPOSE: To provide a welding technique capable of executing welding with an optimum welding method and procedures in the case multilayer build-up welding in a three o'clock position by an automatic welding machine is executed at the time of connecting a square column and a square column by welding on installation site, etc. CONSTITUTION: A welding wire 8 is fed along the outside diameter of a roller 3 to a narrow groove torch 6 if a roller 4 exists below the axial line connecting the rollers 2, 3, 5 which are the wire feeding parts in a wire feeding unit 1 at the time of feeding the wire 8. The permanent set of downward bending is, therefore, added to the wire 8 and since the wire 8 emerges downward from a torch 6, the front end of the wire 8 is capable of aiming the angle part of rear surface of the groove 10. The execution of the welding of the rear surface of the groove 10 without inclining the torch 6 is thus possible. If the roller 4 exists upper than the axial line, the permanent set of upward bending is imparted to the wire 8 and the front end thereof is capable of aiming the angle part of the front surface of the groove 10. Since the continuous lamination of even an I type groove 10 is possible, the automatic welding is efficiently executable.

摘要： PURPOSE:To easily change an electrode and to prevent the projection length of the electrode from changing by supporting a non-consumable electrode of a torch inside a torch body through a taper pin. CONSTITUTION:When an electrode 14 is inserted into an electrode inserting hole and a taper pin 11 is slid in an arrow mark direction with a definite force, the electrode 14 is pressed with the taper pin 11 and supported with the torch body 1. After then, touch sensing and welding are made possible. At the time of changing the projection length of the electrode 14 or changing it with a new one, when the taper pin 11 is slid, fixing of the electrode 14 on the torch body 1 is released. Therefor, the electrode 14 can be fixed or released on or from the torch body 1 by only sliding the taper pin 11.

摘要： PURPOSE: To automate the manufacture of panel and to make the quality of product uniform by continuously performing the edge preparation and bending of a pipe body by the signal of a central control unit and properly arranging working pipes through an assembling robot.
CONSTITUTION: A pipe body is supplied from a stocker 1 to form its edge by an edge preparation machine 2 and is stored in a multi-rack vertically storing stocker 3 in a pipe body working section A. Next, the pipe body is bent by a numerical control bender 4. In a working pipe arranging section B, the pipe sent by conveyors 5a, 5b is arranged so as to form a coil on a conveyor 6 by an assembling robot 7. The pipe arranged for coil is transferred to a panel manufacturing section E through a welding section C and an inspection section D, and is formed into a product by attaching a supporting fixture to it. Because all of the processes are controlled by the storage and command signals outputted from the central control unit the manufacture is automated and the product quality is made uniform.
