Abstract: A welding power source is configured to supply a welding current to a wire as a consumable electrode. The welding power source includes a controller configured to change the welding current based on a position of a distal end of the wire a distance from which to a surface of a base metal varies periodically, in a case where the distal end of the wire is fed toward the base metal with periodical switching between a forward feeding period and a reverse feeding period.

Abstract: A method for displaying an image of a surface of a tire includes: taking an image of a surface of a tire formed with a mark having a protrusion and a recess; acquiring waveform data from the taken image of the surface; creating a histogram from the waveform data; determining, based on the histogram, a first bin threshold to distinguish a surface luminance of the protrusion of the mark, and a second bin threshold to distinguish a surface luminance of the recess of the mark; and displaying the image of the surface of the tire including the mark on a screen by representing a region equal to or higher than the first bin threshold, a region lower than the first bin threshold and higher than the second bin threshold, and a region equal to or lower than the second bin threshold in the histogram in three attributes of color.

Abstract: A method for manufacturing an additively-manufactured object, includes: an additively-manufacturing step of building a layered body by depositing a weld bead obtained by melting and solidifying a filler metal, the layered body having an opening along a forming direction of the weld bead and an internal space surrounded by the weld bead; and a closing step of forming a closing wall portion connecting an edge portion of the opening with the weld bead for closing. In the additively-manufacturing step, the opening is formed with a width dimension larger than a bead width of the weld bead, and in the closing step, the closing wall portion having a width dimension larger than the bead width is formed by the weld bead to close the opening.

Abstract: A method for depositing a hardened layer includes sequentially depositing a hardened layer formed by supplying a powder material for forming a hardened layer, which is obtained by mixing a plurality of kinds of powders, to a substrate, and melting and solidifying the powder material on/above the substrate. The powder material contains a first powder containing an alloy to be serving as a matrix portion of the hardened layer and a second powder containing a ceramic. The method includes heating the powder material until at least a part of the second powder is melted, to allow at least a part of metal elements contained in the melted second powder to be dissolved in the matrix portion of the hardened layer.

Abstract: An oxide layer thickness measurement device according to the present invention stores, for each of layer thickness measurement sub-ranges constituting a layer thickness measurement range, layer thickness conversion information representing a correlation between a layer thickness and an emissivity where a ratio of a change in the emissivity to a change in the layer thickness in the layer thickness measurement sub-range falls within a set extent. Emitting light luminances of a surface of a steel sheet are measured at respective measurement wavelengths different from each other, and a temperature of the surface of the steel sheet is measured to thereby calculate the emissivity at each of the measurement wavelengths. Calculated in connection with the emissivity calculated at each of the measurement wavelength are the layer thickness corresponding to the emissivity at the measurement wavelength, and a ratio at the layer thickness by using the layer thickness conversion information corresponding to the measurement wavelength. The calculated thickness is extracted as a candidate value for an actual layer thickness when the calculated ratio is within the preset extent assigned for the layer thickness conversion information.

Abstract: Provided is a solid wire for gas metal arc welding, which has a small amount of fume during welding and is suitable as a welding material for high Mn steel materials. The wire has a chemical composition containing, in mass %, C: 0.2% to 0.8%, Si: 0.15% to 0.90%, Mn: 17.0% to 28.0%, P: 0.03% or less, S: 0.03% or less, Ni: 0.01% to 10.00%, Cr: 0.4% to 4.0%, Mo: 0.01% to 3.50%, B: less than 0.0010%, and N: 0.12% or less, with the balance consisting of Fe and inevitable impurities. It may contain at least one selected from V, Ti, Nb, Cu, Al, Ca and REM, if necessary. The wire has excellent manufacturability, can significantly suppress the amount of fume generated during gas metal arc welding, and can easily manufacture a weld joint having high strength and excellent impact toughness at cryogenic temperatures.

Abstract: In a rotating machine abnormality detection device, a rotating machine abnormality detection method, and a rotating machine according to the present invention, vibration caused by at least one of first and second rotating bodies is measured, a predetermined feature amount related to a frequency component is obtained based on a frequency spectrum of the measurement data, and determination is made on presence/absence of abnormality based on the obtained predetermined feature amount. On this occasion, when determination is made that abnormality is present, determination whether the determination of abnormality is caused by noise or not is made based on the frequency spectrum, and when determination is made that the determination of abnormality is not caused by the noise, the determined abnormality is ultimately considered as abnormality.

Abstract: The joined body includes a joint portion including a linear welding portion in which a first metal member and a second metal member are joined. The joint portion includes a main linear portion being linear and extending along a first direction being a direction corresponding to a load assumed to act on a component obtained by machining the joined body. The main linear portion is a portion whose angle formed with the first direction is 0 degrees or more and 15 degrees or less in the joint portion. The joint portion includes a plurality of the main linear portions arranged at intervals in a second direction being a direction intersecting with the first direction.
