    Abstract: An apparatus and a method are described for dislodging and removing welding slag from the tip of an electric arc welder, particularly a robotically controlled welder. When a torch finishes its welding cycle, it is moved to a designated cleaning point where it is positioned between two positioning blocks. A double lobed cam on the output shaft of a reciprocating air motor turns against a cam follower. The cam causes the cam follower to compress a spring during the lift portion of the cam cycle, and allows the spring to drive the hammer into impact with the tip during the fall portion of the cycle The repeated impact with the tip serves to loosen the slag from the nozzle. The slag then falls and is collected in a basket located beneath the positioning blocks. The motor rotates at a speed of about 200-1000 rpm to move the hammer about {fraction (3/16)}″ for a cleaning cycle of about 5-10 seconds. The apparatus also includes a positioning device for training a welding robot to precisely locate the impact area for a given size and shape of welding nozzle tip.

    Abstract: A blank tube for cold drawing is used for the production of a longer-length, small-diameter tube such as a heat-transfer tube for steam generation in nuclear power facilities, wherein the blank tube will not cause scoring and chattering vibration in a drawing process. The blank tube is used to produce a cold drawn tube through cold drawing of the blank tube. The average surface roughness Ra (ANSI B46.1) of the inner surface of blank tube before drawing satisfies the condition: 0.10 μm≦Ra≦1.00 μm in the case of a blank tube for cold drawing for use in an oil-lubricated drawing. In particular, the surface roughness Ra satisfies the condition: 0.10 μm≦Ra≦0.50 μm in the case of a blank tube for use in a high-pressure lubrication drawing and made of an austenitic alloy for use in a heat-transfer tube for a steam generator.

    Abstract: A scraper blade holding system on scraper shafts of scraper coolers in which the scraper blade, by means of springs, connecting elements, and guiding elements for the springs, is in continuous contact with the inner wall of the inner tube of a double tube structure. The scraper blade holding system is characterized primarily in that transverse bores of the scraper shaft end are freely axially movably arranged holding bolts which at their outer ends directed to the inner wall of the inner tube are equipped with tubular sleeves connected to the scraper blades, which sleeves are pressed outwardly by helical pressure springs surrounding the holding bolts and are supported by the scraper shaft.
