摘要： PURPOSE:To make possible the prevention of deterioration of working environments, improvement of material yield and application of a uniformly thick coat by ejecting resin powder in a spraying box, and applying/melting the resin powder on the surface of a metal to be heated, while aspirating and recovering a floating resin powder which does not stick and melt. CONSTITUTION:An exposed metal section 12 is heated from an opposite side to a spraying box 42 by a burner 21 of a heating device 2 at more than a melting-point temperature of resin powder 63. Consequently, the resin powder 63 ejected from a spray nozzle 45 in the spraying box 42 melts, and sticks and melts with the existing lining coat into a mixed film. The portion which does not stick and melt of the resin powder 63 ejected from the spray nozzle 45 floats in the spraying box and then is sucked into a powder recovery device 6. Thus the density of powder can be controlled. Therefore, the coat thickness can be controlled by adjusting the spraying time or the movement speed of the spraying box 42. This makes it possible to obtain a uniformly thick lining at all angles of spraying.

摘要： PURPOSE:To reduce an installation area and improve working efficiency, by engagingly arranging a plurality of swifts with element wires wound around them in a lengthwise direction with respect to a longitudinal shaft in a multi-stage and shaping and gathering the respective element wires by drawing out them by an unwind end holding means and a drag-in means. CONSTITUTION:A plurality of swifts with element wires wound around then are engagingly arranged in a lengthwise direction with respect to a longitudinal shaft and pivotally engaged. A reverse-L-shaped support member 17 is slidably engaged with a horizontal support arm 16 at the upper end of the shaft. Clamp rollers 21 are mounted on the horizontal portion of the arm at its locations confronting the element wires 2 of the respective swifts and a plurality of lock metal fittings are also attached thereto and engaged with drag-in cylinders 31 of drag-in and transfer units 23 disposed in front of them. When the element wire is held by an unwind end holding roller 21, the arm 17 is dragged in by the cylinder 31, the element wire 2 is gripped by a transfer drive roller 27 and inserted into a conduit tube 9 by driving a motor 25. Then, it reaches a shaping and bundling device. With such an arrangement, an installation area is reduced and manpower is not necessary.

摘要： PURPOSE:To simply and rapidly execute the fitting as well as adjusting operations and improve the operational efficiency in such a work as oblique cutting of a straight pipe, by providing a fastening mechanism fastening it to the pipe body so that a circular surface of the guide rail can be approached specially for a center of the pipe. CONSTITUTION:A circular guide rail 2 for automatic welding is fastened to a laterally cut pipe 1 so that the reference surface A-A is positioned in parallel with a terminal surface of the oblique cutting pipe 1, and kept inside by a distance L. In this case, by using a fastening mechanism 17 at closing point in the direction of longitudinal axis of the end face of ellipse-shaped tube, the circular guide rail 2 is fastened to the pipe body 1 so that the circular surface of the guide rail can be fixed as being approached to the center of the pipe by Ltantheta (theta is an inclination of a center line of the guide rail to the axis of the pipe) while keeping strictly the fixed eccentricity. In this case, the fastening mechanism 17 is consisted of one or two rods with screw threads 8. As stated above, there is no fear that the position of the circular guide rail 2 is shifted.

摘要： PURPOSE:To perform resin lining on the internal surface of a large diameter pipe by heating along the entire periphery of the large diameter pipe by burners provided on trucks while traveling the trucks along a rail device which is mounted on the periphery of a portion, to be heated, of the large diameter pipe. CONSTITUTION:A rail device 5 consists of a pair of rails 7 made of H-steel, a frame 8 that holds the rails 7 at a specified interval, reinforcement members 9, jack bolts 10, etc. The rail device 5 is mounted on a welded joint part of a large diameter pipe 1 being resin-lined on its internal surface, at the position a specified internal apart from the pipe wall and across the welded joint part. A truck 16 is mounted on the rail device 5, and a driving truck 16A travels along the large diameter pipe 1 in the peripheral direction. Combustion gas is supplied to burners 28 and 29 mounted on heating trucks 16B and 16C to heat the pipe wall by the burners 28 and 29. Thermoelastic resin 52 is contacted by an adequate method on the internal surface to be heated. The track 16 travels around the whole periphery of the large diameter pipe 1 to heat the pipe wall throughout the periphery, so that resin lining is formed on the internal surface.

摘要： PURPOSE:To enable all position non-gap TIG automatic welding of fixed tube, by providing two gas pressure controlling nozzles at right angles to the direction of advance of welding and one in the rear around the electrode, feeding the wire from the front, and thereby cooling the arc and the surface of motlen pool and performing root pass penetration welding. CONSTITUTION:An arc is deflected to the front by gas jetted from the rear to the direction of advance of welding. At the same time, the surface of molten metal right under the arc is cooled forcibly to form a solidified layer positively. The arc is narrowed down thinly in vertical direction by jetting gas from nozzles 7-2, 7-3 for gas pressure controlling and concentrative force of the arc is heightened and arc force is strengthened to enable penetration welding. At the same time, molten metal on the side of groove is checked by jetting gas shown by the arrow 7' to form a solidified layer positively. Thus, root pass penetration welding is performed stably at all times and at all positions.
