    摘要: Systems and apparatus are disclosed relating to smart regulators and smart manifolds for welding-type systems. A smart regulator may be coupled to a fluid tank and provide information regarding the current pressure(s) and/or flow rate to a remote device and/or operator. The remote device may also determine and/or output additional information, such as, for example, remaining fluid and/or remaining time before the fluid runs out or becomes dangerously low. A smart manifold may be configured to work with several different fluid supplies. In this way, an operator may easily mix fluid types, switch between different fluid types, and/or switch between different fluid tanks.

    摘要: Provided is a welded structural member with excellent stress corrosion cracking resistance, which includes: a 7000-series aluminum alloy material that has a chemical composition containing 6.6% by mass to 8.5% by mass of Zn, 1.0% by mass to 2.1% by mass of Mg, 0.10% by mass to 0.20% by mass of Zr, and 0.001% by mass to 0.05% by mass of Ti, with a remainder including Al and unavoidable impurities, and includes a metallographic structure that is a fibrous structure; and other aluminum alloy material welded with the 7000-series aluminum alloy material. In this welded structural member, when an electrical conductivity of the 7000-series aluminum alloy material before an artificial aging treatment is defined as X % IACS and the electrical conductivity of the 7000-series aluminum alloy material after the artificial aging treatment is defined as Y % IACS, the following equation is satisfied: 0.120≤(Y/X−1)≤0.250 is satisfied, and a difference in the electrical conductivity of the 7000-series aluminum alloy material between a mother portion other than a weld heat-affected zone and the weld heat-affected zone is 5% IACS or less.

    摘要: To provide a method and apparatus for manufacturing a joined member that inhibit occurrence of cracks in a joined member even when the joined portion is quenched when members are welded together. The method includes placing the first member D and the second member E with a joint target portion Df and a joint target portion Ef being in contact with each other, welding the joint target portions by heating, subjecting the first member D after the welding to a process for inhibiting occurrence of cracks, and tempering a portion where the first and second members have been welded to each other by electromagnetic heating. The apparatus includes a first electrode 11 to contact with the first member D; a second electrode 12 to contact with the second member E; and an induction heating coil 23 for performing induction heating of a portion where a joint target portions Df and Ef have been contacted and joined to each other, and the induction heating coil 23 is placed between the two electrodes 11 and 12 when the induction heating is performed.

    摘要: An apparatus for predicting and/or reducing a deformation of an assembly brought about during production of a weld seam that connects a first component and a second component of the assembly includes a device that is configured to determine and/or provide a finite element (FE) model of the assembly where the FE model includes a set of FEs for the weld seam and a set of FEs for the first component and the second component. The device is further configured to induce a spatial contraction of the set of FEs for the weld seam, determine an effect of the spatial contraction on the set of FEs for the first component and/or the second component, and predict a spatial deformation of the first component and/or of the second component on a basis of the effect on the set of FEs for the first component and/or the second component.

    摘要: A precipitation-strengthened cast product welding repair method is a method of repairing a damaged portion of a precipitation-strengthened cast product. The method includes: forming a first weld layer on a surface of the damaged portion by micro tungsten inert gas (TIG) welding using a solid-solution-strengthened welding material having higher toughness than the cast product; and forming a second weld layer on the first weld layer by building up the second weld layer by laser welding using a dual multi-phase nanostructure intermetallic compound as a welding material and being higher in heat supply rate than the micro TIG welding.
