An assembly method of a SMA assembly, includes disposing a lens holder unit on a SMA unit, the lens holder unit being provided with a first spring, a lens holder and a coil that are mounted on the first spring, with the first spring pressed against a mounting surface of the SMA unit; and bonding the first spring of the lens holder unit with the mounting surface of the SMA unit. The assembly process is simplified, the coating and soldering space become big to facilitate the bonding process, and the joining force between the SMA unit and the lens holder unit is enhanced.

A method and apparatus manufactures a closed structure part without flange having a curvature and welded edges along a longitudinal direction of the part and further having a varying cross-sectional shape, from two metal plates. Each of two metal plates provided with a curvature along the longitudinal direction of the plate and provided with both ends in a width direction of the plate, are press-formed such that a folding line is formed at positions corresponding to a non-welded bent edge in a cross section of the part, and stacked on each other vertically such that their bulging sides face outward. Their left ends and right ends in the width direction are mutually welded along the longitudinal direction to form welded edges.

A method and apparatus for joining parts. A plurality of conformable induction coils embedded in a number of elastomeric sheets is positioned relative to a first composite part of the parts and a second composite part of the parts. A magnetic field is generated with the plurality of conformable induction coils. The magnetic field is configured to generate heat in a magnetically permeable material at a joint location. The heat joins the first composite part and the second composite part to each other.

The present invention concerns methods and apparatus for forming a clad product, such as a clad pipe or tube. Particular embodiments include a method for metallurgically bonding cladding material onto a metal substrate, the method including a step of providing a metal substrate comprising a pipe or a tube having a cladding composition arranged along an interior surface of the substrate to form a coated substrate, the interior surface arranged within an interior cavity of the substrate. A further step includes inserting a heat source into an interior cavity of the substrate, the heat source comprising an infrared, microwave, or radio frequency heat source, the heat source being mounted on a heat source-retaining housing, the housing comprising a cantilevered structure. An additional step includes applying heat discharged from the heat source to the coated substrate along the coated interior surface until the cladding composition metallurgically bonds to the substrate.

A method of manufacturing a molded product is provided. The method of manufacturing a molded product includes forming a first joining portion by placing an inner metallic plate and an outer metallic plate on each other and welding them together; bending, after forming the first joining portion, the outer metallic plate with the inner metallic plate in a first direction by performing a first press working; and forming, after the first press working, a first surface, a second surface, and a curved portion on the outer metallic plate by performing a second press working. In the second press working, the outer metallic plate is bent with the inner metallic plate in a second direction to form an oppositely curved portion which is bent in a direction opposite from a bending direction of the curved portion on the outer metallic plate.
