A method for forming an abrasive surface includes utilizing an energy source to form a melt pool layer in a substrate and applying abrasive grit into the melt pool layer. A method for forming an abrasive surface including applying an abrasive grit to a substrate and utilizing an energy source to form a melt pool layer in the substrate without disturbing the abrasive grit such that the abrasive grit becomes embedded in the melt pool layer.

A method for solid-state, one-shot, butt-welding of multiple coaxial metal pipe subassemblies that have a prescribed annular clearance to allow them to be welded separately yet simultaneously is described. The nested pipes or tubes making up of these subassemblies can thus be joined end to end to form pipelines or wells for oil, gas and geothermal and the like with specific desired advantages over conventional single-wall pipelines or wells casings. The advantages include an ability to monitor the condition of all or selected portions of the pressure envelope constituted by the pipeline or well casing and thereby identify damage with ample advance warning before failure and leakage or major spills occur.

A method (e.g., for creating a printing plate assembly of an ink jet print head assembly) includes coating one or more sides of plural planar subsection plates with a bonding material. The subsection plates include printing holes through which a fluid is to be ejected from the ink jet print head assembly. The method also includes placing the subsection plates of the printing plate assembly against each other with the printing holes axially aligned with each other and heating the bonding material between the subsection plates such that the subsection plates are affixed to each other. The subsection plates are coupled with each other to form a chamber printing assembly that is coupled to the ink jet print head assembly that prints fluid onto one or more objects by ejecting the fluid out of the printing holes of the subsection plates. The subsection plates may be hermetically bonded to each other by inductively heating the assembly.

A bonding apparatus includes a support member configured to support a first substrate of a display panel and a connecting member, a bonding unit located above the support member and configured to compress the first substrate and the connecting member against each other using a bonding head to which a heating member is attached, and a magnetic-field generating part configured to generate a magnetic field to heat the heating member in an electromagnetic induction method.

A method connects at least two components made of different materials by thermal joining. The two components include a first component made of a material that is suitable for thermal joining and a second component made of a material that cannot be processed using the thermal joining method of the first component. The method includes introducing an auxiliary joining part into the second component forming a form-locking connection and/or a force locking connection. The auxiliary joining part of is made of a material that can be thermally joined to the first component. The first component is thermally joined to the auxiliary joining part in the second component so as to produce a connection between the first component and the second component. The thermal joining is carried out by a beam welding method.

The invention discloses a method and an apparatus for metal three-dimensional printing, in which the method for metal three-dimensional printing comprises the following steps: molten or softened flowable metal is placed in a build area used by a three-dimensional printing device, after having no fluidity, the molten or softened flowable metal is converted into metal built by printing, the molten or softened flowable metal is accumulated on the basis of the metal built by printing, until an object to be printed is built, and the accumulated metal built by printing forms the object to be printed; the key characteristics are as follows: in the building process, the interlayer binding force and the binding force between pixel points are changed through a manner of resistance heating; and a printing area for implementing resistance heating can be set. The metal component generated has high strength, high density, and high building precision, the building process of each pixel point is monitored, a removable auxiliary support can be generated synchronously, a large-scale component can be printed, and the apparatus is simple in structure and low in cost. The present invention possesses a substantial progress.
