A method for producing a high temperature component includes a shaping step of shaping a powder compact of a desired high temperature component shape using a specific powder shaping method, from an alloy powder of &#x3b3;' precipitation strengthening-type Ni-based alloy, and a crystal grain coarsening step of coarsening a crystal grain size of the powder compact by heat treatment, wherein the powder compact contains 0.002% or more and 0.07% or less of C, and 5.40% or more and 8.40% or less of Al+Ti by mass percentage.

High temperature component and method for producing same

A welding torch includes a torch body including a flow path forming portion that forms a shielding gas flow path into which an inert gas flows and an outer gas flow path communicating with the shielding gas flow path, a first gas lens that straightens the inert gas in the shielding gas flow path and blows the inert gas out as a shielding gas, and a second gas lens that straightens the inert gas in the outer gas flow path and blows the inert gas out as an outer gas. Provided is an all-position welding device that performs butt welding of tubes, and includes the welding torch and a rotation mechanism for rotating the welding torch around the tube.

Welding torch and all-position welding device

A welding torch includes a gas lens of a lattice structure that straightens a shielding gas. The welding torch includes a non-consumable electrode, an electrode holder into which the non-consumable electrode is inserted, and a torch body including a sleeve that holds the electrode holder, a flow path forming portion that forms a shielding gas flow path around the sleeve, and a nozzle that forms a shielding gas guiding space around a distal end of the non-consumable electrode, the distal end extending from the electrode holder, in which the gas lens is provided so as to separate the shielding gas flow path from the shielding gas guiding space.
