Publication number: 20150129560Abstract: Provided are a plasma-MIG welding method and a welding torch that are capable of reducing spatter amount without relying on control of a MIG welding power supply. The plasma-MIG welding method employs a plasma-MIG welding device configured from: a plasma torch section that includes a plasma nozzle and a plasma electrode; and an MIG torch that includes an MIG tip and a welding wire. The plasma torch section and the MIG torch are arranged so as to face in different directions at a predetermined distance from each other. The plasma-MIG welding method is characterized in that a plasma arc is made to locally overlap with a tip end portion of the welding wire, and in a state in which melting of the welding wire is promoted, MIG welding is carried out without short-circuiting between a workpiece and a tip end of the welding wire which is a consumable electrode.Type: ApplicationFiled: February 18, 2013Publication date: May 14, 2015Inventors: Yusuke Muramatsu, Katsuya Matsumoto, Jun Kitagawa, Keishi Setoda

Patent number: 8513564Abstract: A plasma welding torch that can be reduced in size more than in conventional cases. When an inert gas G such as argon gas is supplied to an outer circumferential space around a non-consumable electrode 13, a portion of the inert gas G is used as plasma gas GP that forms a plasma arc PA between the non-consumable electrode 13 and a base material 2 via a plasma orifice 51. A plasma welding torch 1 moves, maintaining this state, in the direction of the arrow shown in FIG. 4. Meanwhile, a portion of the inert gas G supplied to a gas flowing part 21 is not used as the plasma gas GP but is used as shielding gas GS and is ejected onto the base material 2 ahead in the welding direction via a shielding orifice 52. The welding on the base material 2 is performed in a state where the plasma arc PA and the base material 2 are shielded from the air by this shielding gas.Type: GrantFiled: February 14, 2011Date of Patent: August 20, 2013Assignee: Honda Motor Co., Ltd.Inventors: Katsuya Matsumoto, Jun Kitagawa, Keishi Setoda, Yusuke Muramatsu

Patent number: 7422042Abstract: An apparatus for centering a log to allow an optimum yield axis and a maximum radius of rotation of the log to be calculated more accurately than conventionally possible. The angle of rotation of a log M is detected by a rotation angle detector that is engaged with a preliminary axis c about which the log M is rotated. A contour of the log for calculating the optimum yield axis of the log and a contour for calculating the maximum radius of rotation of the log are measured separately. The contour for calculating the optimum yield axis is measured in a fixed-point manner by measuring the log at a plurality of certain measurement points with beam reflection scanners. The contour for calculating the maximum radius of rotation is measured in a comprehensive manner using swing-angle detectors engaged with contact-swinging detection members provided individually in the plural measurement sections.Type: GrantFiled: April 20, 2004Date of Patent: September 9, 2008Assignee: Meinan Machinery Works, Inc.Inventors: Nobuyuki Moriyama, Kazuhito Mawatari, Fumihiro Mizutani, Yukinobu Kuno, Katsuya Matsumoto, Masaru Koike
