8 results about "Faying surface" patented technology

A method is provided for forming a large metallic component using a friction stir welded blank. A first and second metallic plate are positioned in an abutting arrangement with corresponding faying surfaces. A backing plate is attached across the abutment. The plates are friction stir welded along the faying surfaces, the friction stir weld including a weld root that terminates in the backing plate. After welding, the backing plate is removed, including the weld root, to create a welded blank. The blank is then formed into a desired component shape, heat treated and aged to produce the final large metallic component. The resulting friction stir weld has a stable microstructure with minimal or no abnormal grain growth during high-temperature forming, heat treatment, or aging.

The present invention provides a method for manufacturing a reactor and a reactor that firmly joins the molded core and molded coil, and prevents damage to the welded joints of the busbar and lead wires. [Solution] The method for manufacturing the reactor includes an adhesive bonding step of joining molded cores 1a, 1b and molded coil 5 with an adhesive, and a welding step of connecting the lead wires of the coil 6 and the busbar fixed to the molded core 1a by welding. The coil 6 is mounted on the leg portion 23. The adhesive bonding step includes applying adhesive 8 to the joint surface 231 of the leg portion 23 of the core member and the inner circumferential surface 241 of the yoke portion 24, pressing the applied adhesive 8 to spread it out, and a curing step for the adhesive. In the pressing step, the adhesive 8 applied to the joint surface 231 is pressed out, causing it to overflow onto at least one of the upper and lower surfaces of the leg portion 23, and at least one of the inner side surface 236 and outer side surface 237 of the leg portion 23, and to adhere to the molded coil 5.

A thick steel plate assembly welded by laser welding and a laser welding method thereof are disclosed. The thick steel plate assembly comprises two steel plates and a filler region. A joint face of the steel plates extends along a joint line. At least one portion of the joint face of one of the thick plate steels is formed with a groove along a grooving line. The filler region is formed by feeding a filler into the groove and using a laser to weld the joint face having the groove through the filler. After the filler region is cooled and solidified, the thick steel plates are combined with each other. A thickness of each filler layer in the filler region is between 4 and 6 mm. Thus, the process can be simplified greatly and the cost can be reduced.

The invention provides a method for manufacturing a reactor and a reactor, wherein a molded core and a molded coil are firmly jointed, and a welding part of a bus bar and a lead wire is prevented from being damaged. A method for manufacturing a reactor includes: a bonding step of bonding a molded core and a molded coil with an adhesive; and a welding step in which the lead wire of the coil is connected to the bus bar fixed to the mold core by welding. The coil is attached to the leg portion. The bonding step includes: a coating step in which an adhesive is applied to the bonding surface of the leg portion of the core member and the inner peripheral surface of the yoke portion of the core member; a pressing step for pressing and spreading the applied adhesive; and a hardening step for hardening the adhesive. In the pressing step, the adhesive applied to the bonding surface is pressed and spread out to be extruded to at least one of the upper surface and the lower surface of the leg part, and extruded to at least one of the inner side surface of the leg part and the outer side surface opposite to the inner side surface of the leg part, which are the surfaces of the leg part facing each other, and the adhesive is attached to the molded coil.

A connector for use in an ultra-high vacuum system is disclosed herein. The connector has a metal conduit section with a first hardness, a metal fitting with a second hardness greater than the first hardness, and a metallic reaction-inhibiting barrier positioned between the conduit section and the fitting to sealingly attach the fitting to the conduit section. In some embodiments, application of a mechanical stressor such as stretching or treatment with a mechanical oxide disruptor removes oxide from and prevents oxide re-formation on the faying surface of the conduit section. In alternate embodiments, oxide is removed from the faying surface of the conduit section and oxide re-formation is subsequently prevented by applying an oxide inhibitor. The reaction-inhibiting barrier substantially inhibits metallic and chemical interaction between the conduit section and the fitting under ultra-high vacuum, temperature cycling, mechanical stress, and reactive chemical conditions, as are present during manufacturing.
