| 20150352656 | ARC WELDING SYSTEM, METHOD FOR PERFORMING ARC WELDING, AND METHOD FOR PRODUCING WELDED PRODUCT - An arc welding system includes a feeder to feed a consumable electrode to a welding torch. A power source supplies power to between the electrode and an object. A welding controller controls the feeder and the power source to cause a short-circuit state and an arc state to repeat between the electrode and the object. A robot moves the welding torch along a welding line. A robot controller controls the robot. A detector detects whether a state between the electrode and the object is the short-circuit state or the arc state. A determiner determines whether a first period or a second period has elapsed since the detector detected the arc state. An instructor instructs the robot controller to decelerate the welding torch when the determiner determines that the first period has elapsed, and to stop the welding torch when the determiner determines that the second period has elapsed. | 12-10-2015 |

| 20090039062 | TORCH BRAZING PROCESS AND APPARATUS THEREFOR - A process and apparatus for brazing a metal alloy component, such as a superalloy component of a gas turbine engine. The process employs a plasma torch in a non-transferred arc mode to generate an electric arc between an electrode and a housing in which an orifice is defined. A plasma gas is flowed through the arc so as to ionize the plasma gas, and the resulting ionized plasma gas is discharged through the orifice to form a plasma jet. The plasma torch is configured so that the plasma jet is shrouded from a surrounding oxidizing atmosphere by a shielding gas flowing cocurrently with the plasma jet. A braze alloy material is introduced into the plasma jet, which is directed at a surface of the component to form a brazement that is metallurgically bonded to the component without melting the component. | 02-12-2009 |
