System and method of manufacturing high-strength bonded metal sheets for a battery cell are provided. The method comprises providing a stackup comprising a first metal sheet and a second metal sheet. The first and second metal sheets are separated by a first coating layer. The first coating layer comprises nickel-phosphide. The first metal sheet includes a first material of a first melting point and the second metal sheet includes a second material of a second melting point. The first coating layer including a third material of a third melting point. The method further comprises heating the stackup to allow crystallization of nickel in the first coating layer and remove the residual nickel-phosphide defining an enhanced coating layer. The enhanced coating layer comprises crystallized nickel for high-strength solid state bonding of the first and second metal sheets to the enhanced coating layer.

A metallic component includes a core formed of steel. A zinc alloy layer is disposed on the core. The zinc alloy layer is formed of zinc and a very small amount of aluminum, such as 0.14 weight percent or less. A method of creating a component includes providing a steel core, providing a zinc bath consisting of essentially of 0.01 to 0.14 weight percent aluminum, and hot dipping the steel core into the zinc bath to form a zinc coating on the steel core resulting in a zinc-coated steel component. The aluminum may be provided in even lower contents, such as less than 0.08 weight percent, or even less than 0.05 weight percent. The zinc-coated steel component may then be spot welded to another component without first annealing the zinc-coated component. Rather, heat treating is performed locally at the weld joint by the welding procedure alone.

A method of making a connector assembly includes attaching two stamped housing sections together to form a connector housing having a housing groove with a groove bottom and two side walls and providing the connector housings with a spring used as a mechanical connector and/or as an electrical connector for numerous applications and across numerous industries. The groove geometries can easily be altered using different stamping dies.

A method for automatic welding of a structural steel assembly includes workpieces such as profiles and/or a sheet material. The method includs using an automated process to receive information from a CAD-CAM program about welds for welding the structural steel assembly, and to post-process the information received from the CAD-CAM program. The information of each single weld received from the CAD-CAM program includes data about e.g a type of a workpiece or of workpieces of the structural steel assembly which bound the weld, a weld type, a position of the respective weld relative to the workpieces of the structural steel assembly that bound the weld, a shape of the weld, a length of the weld, a path of the weld and a width of the weld. The post-processing includes splitting each weld in sections of which the individual welding parameters are predefined.

Provided is a resistance spot welding method. The resistance spot welding method for joining a sheet set including a plurality of lapped steel sheets includes: holding the sheet set between a pair of electrodes; and energizing the sheet set under application of electrode force to thereby join the steel sheets together. At least one of the plurality of lapped steel sheets is a surface-treated steel sheet including a metal coating layer on a surface thereof. The energizing includes: a primary energizing step of performing energization to form a nugget portion; a non-energizing step in which, after the primary energizing step, the energization is suspended for an energization suspension time Tc (cycles); and a secondary energizing step of, after the non-energizing step, performing energization for reheating while the nugget portion is prevented from growing. During the energizing, the relations of a particular formula are satisfied.

It is an object of the present invention to provide a method of producing a vacuum thermal insulation panel capable of reducing the occurrence probability of poor welding of a metal outer wrapping material. The method of producing the vacuum thermal insulation panels 100, 100A to 100 D, 101, 101A according to the present invention includes a “covering step of covering a core material 110 or 110B with a metal foil 130 or 131” and a “welding step of welding a metal foil portion on an outer side of the core material”, and the core material is at least partially covered with a cover 120, 120A, or 120D at a timing when the covering step is to be started. Note that when the entire surface of the core material is covered with the cover, it is preferable to reduce the inside of the cover to seal the cover before the covering step, and when a part of the core material is covered with the cover, it is preferable to simultaneously reduce a pressure inside the metal foil and a pressure inside the cover to seal the metal foil.
