Provided is a clad welded pipe or tube that has improved pipe or tube mechanical properties by reducing the width of a weld without its function as a clad pipe or tube being impaired. A clad welded pipe or tube comprises: a first layer made of base metal; and a second layer placed on one surface of the first layer, and made of first cladding metal that is a material different from the base metal, wherein a pipe or tube circumferential length L1 of weld metal at a pipe or tube inner surface and a pipe or tube circumferential length L2 of the weld metal at a pipe or tube outer surface in a weld are each 0.0010 mm or more and 1.0 mm or less, and the base metal is not exposed at a first cladding metal-side surface of the clad welded pipe or tube in the weld.

A system may include a powder source; a powder delivery device; an energy delivery device; and a computing device. The computing device may be configured to: control the powder source to deliver metal powder to the powder delivery device; control the powder delivery device to deliver the metal powder to a surface of an abrasive coating; and control the energy delivery device to deliver energy to at least one of the abrasive coating or the metal powder to cause the metal powder to be joined to the abrasive coating.

A method of reprocessing a metal product includes a welding step for welding a dummy member to the metal product, a reprocessing step for reprocessing the metal product in a state where the metal product is supported by a first support unit and the dummy member is supported by a second support unit, and a removal step for removing the dummy member from the metal product after the reprocessing step. The reprocessing of the metal product while the metal product is fixed is thus enabled without restriction from the shape of the metal product.

Example illustrations are directed to methods and apparatuses comprising battery cells having weld joints. In an example method, a laser is moved to a shoulder of a battery cell. The method may further include micro welding with the laser a first line segment on the shoulder of the battery cell and moving the laser a distance on the shoulder of the battery cell. The method may also comprise micro welding with the laser a second line segment on the shoulder of the battery cell in response to moving the laser the distance. Example battery cell assemblies, e.g., for a battery pack, may have a battery cell and a weld joint on a shoulder of the battery cell. The weld joint may include a first micro weld line segment and a second micro weld line segment separated by a distance.

A manufacturing method is provided during which a plurality of first apertures are formed in a first plate to provide an apertured first plate. A plurality of second apertures are formed in a second plate to provide an apertured second plate. The apertured first plate and the apertured second plate are bonded to a base sheet to form a structure. The base sheet is bent to form a bend in the structure between the apertured first plate and the apertured second plate.

Nickel-based superalloy suitable for additive manufacture, a method, and a product includes a special selection of the elements silicon, boron, zirconium, and hafnium. The nickel-based superalloy includes at least the following (in wt.%): carbon (C) 0.04%-0.08% chromium (Cr) 9.8%-10.2% cobalt (Co) 10.3%-10.7% molybdenum (Mo) 0.4%-0.6% tungsten (W) 9.3%-9.7% aluminum (Al) 5.2%-5.7% tantalum (Ta) 1.9%-2.1% boron (B) 0.0025%-0.01% zirconium (Zr) 0.0025%-0.01% hafnium (Hf) 0.1%-0.3%, and optionally yttrium (Y) and residual nickel (Ni).

A process of modifying a passage in a component is provided. The process includes inserting a first material into the passage; blocking at least one end of the passage; inserting an elongated member into the passage through the first material; heat treating the passage, the first material, and the elongated member to form a solid interior in component; and machining through the solid interior to form a modified passage in the component.

A method of applying a braze component to a honeycomb structure may comprise: applying at least a partial vacuum within a chamber, the chamber defined at least partially by a vacuum device and a cover, the honeycomb structure disposed within the chamber, the braze component disposed between the honeycomb structure and the cover; pulling the cover towards the braze component in response to applying the partial vacuum; and pulling the braze component into a plurality of hexagonal cells defined by the honeycomb structure in response to pulling the cover towards the braze component.

Disclosed is a clad steel plate with further improved low temperature toughness along with excellent HIC resistance while ensuring a tensile strength of 535 MPa or more. A clad steel plate includes: a base steel; and a clad metal made of a corrosion resistant alloy bonded to one surface of the base steel, in which the base steel has: a chemical composition with appropriately controlled values of ACR and P.sub.HIC; and a steel microstructure in which bainite is present in an area fraction of 94% or more at a ½ thickness position in a thickness direction of the base steel, and with an average crystal grain size of 25 μm or less, and shear strength at a bonded interface between the base steel and the cladding metal is 300 MPa or more.

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.
