Publication number: 20070034610Abstract: The object of the present invention is to achieve a deep weld penetration in a welded portion in metal by setting appropriate conditions for welding without deteriorating the quality of welding. That is, in the present invention, the weld penetration can be made deep by using a shielding gas comprising: 0.2% by volume or more (preferably 0.4% by volume or more) of oxygen gas; and the balance being helium gas, and by further setting the other welding conditions, such that the concentration of oxygen in the welded metal in the range of 70 to 700 ppm, and the scale ratio, i.e. the value D/W, can be made large. According to the present invention, a deeper weld penetration can be achieved without deteriorating the quality of welding by adopting at least one selected from the appropriate conditions of the welding current, the welding speed, and the arc length.Type: ApplicationFiled: August 9, 2006Publication date: February 15, 2007Applicants: TAIYO NIPPON SANSO CORPORATION, OSAKA UNIVERSITYInventors: Toshimitu Ochiai, Toyoyuki Sato, Hidetoshi Fujii, Kiyoshi Nogi, Shanping Lu

Publication number: 20040188390Abstract: A TIG welding equipment and a TIG welding method are described, capable of forming a welded metal portion deeply without lowering the welding quality, making the welding performance easier and improving the welding efficiency. The TIG welding equipment includes an electrode 2 for generating an electric arc 7 between itself and the welded object 10, a tubular inner nozzle 3 disposed surrounding the electrode 2, and a tubular outer nozzle 4 disposed surrounding the inner nozzle 3. A first shielding gas 8 composed of an inert gas can be supplied from the inner nozzle 3, and a second shielding gas 9 containing an oxidative gas can be supplied from between the inner nozzle 3 and the outer nozzle 4.Type: ApplicationFiled: March 19, 2004Publication date: September 30, 2004Inventors: Toyoyuki Satou, Koji Nakamura, Yutaka Kimura, Hidetoshi Fujii, Shanping Lu, Kiyoshi Nogi
