One aspect relates to a feedthrough system. The feedthrough system includes a feedthrough and a wire. At least a portion of the feedthrough is made of an insulator and at least one area forming an electrically conductive cermet pathway. The cermet pathway may include an electrically conductive metal. The wire may be at least partially connected to the cermet pathway so that the material of the wire forms a joint microstructure with the electrically conductive material in the cermet pathway.

An electrode used for resistance welding is described. In an embodiment, the electrode comprises a two-part construction having an electrode tip portion that is removably contactable to an electrode base. The electrode is constructed such that the respective base and electrode tip portions may be composed of metals having differing melting temperatures, in particular a significant difference in melting temperature of at least 100 C. or more. The electrode is preferably constructed so that the electrode tip portion can be easily removed, thereby leaving the base portion within the fixture.

A method for manufacturing a joined member and a joined member manufacturing apparatus which can manufacture a joined member with a joint portion having an appropriate hardness. A method for manufacturing a joined member C by joining a first member D formed of a metal material having a possibility of undergoing quenching and a second member E formed of a metal material, the method includes a contact-placing step S1 of placing the first and second members D and E with joint target portions of the first and second members D and E respectively being in contact with each other; a joining step S2 of joining the first and second members D and E by passing a pulsed welding electric current A1 for joining through the joint target portions J of the first and second members D and E; a first tempering step S3 of tempering a joint portion F, where the first and second members D and E are joined, by passing a first tempering electric current A2 through the joint portion F; and a second tempering step S4 of tempering the joint portion F by passing a second tempering electric current A3 smaller than the first tempering electric current A2 through the joint portion F.

A cylinder pipe assembly has a connection piece, and cylinder pipe with a main body and a connection portion. The connection portion has an outer shell calotte on a cylinder pipe outer shell and an inner shell calotte on a cylinder pipe inner shell, a connection hole, and a structural consolidation zone surrounds the connection hole. The calottes are concave embossed portions. The structural consolidation zone is arranged in a region between the calottes. The connection hole is punched and passes through the calottes. The connection piece is arranged at the connection portion and has a pressure medium tube and a connecting portion with an annular axial boundary contour that with an annular mating surface defines an annular contact surface. The cylinder pipe and the connection piece are connected in a bonded manner by an annular weld seam, and the weld seam defines a sealing plane.

A welding method for a new flexible and rollable silicon-based solar module includes the following steps: cutting a cell piece into a small piece cell string including N small piece cells without splitting; cutting a hard protective layer into N small pieces according to a size of a small piece cell; allowing the cut hard protective layer to be covered on and bonded to a glue-dispensed small piece cell string to form a small string cell piece; arranging the small string cell pieces into a small standard piece according to a required size distribution, and covering the small standard piece with an adhesive film; welding positive electrodes and negative electrodes of the small standard pieces in series simultaneously to form a 1P standard part; and arranging the 1P standard parts, and fixing the 1P standard parts by bonding the adhesive films to each other to form a 5P standard part.

A method of welding comprising contacting a first electrode to a porous body flow path, contacting a second electrode to a plate material, pressing the porous body flow path and the plate material by the first and second electrodes in a thickness direction of the plate material, and spot welding the porous body flow path and the plate material, wherein: a deformation of the plate material in a direction of the second electrode pressing the plate material is smaller than a deformation of the porous body flow path in a direction of the first electrode pressing the porous body flow path.

Disclosed are a filter structure, a welding fixture, and a manufacturing method of the filter structure. The filter structure includes: a box having a cavity; coil components installed in the cavity; and wiring components, each having a positive wiring pin and a negative wiring pin fixed to the box. The conductive wire has conductive wires coupled to both ends of the coil component and welded with the positive and negative wiring pins respectively. After a wiring section of the pins is embedded into a side of a wire latch slot, the conductive wire of the coil is latched into the wire latch slot and welded with the pins by spot welding without the need of manually winding the conductive wire and the pins, so as to reduce labor, expedite assembling, improve production efficiency and save material cost of the conductive wire.

A guide mechanism includes: a guide member having a first groove; a slide member having a second groove; and rolling bodies arranged in a guide groove comprising the first groove and the second groove. A stopper for preventing the rolling bodies from moving out of the guide groove is affixed to the second groove by welding. A method for manufacturing the guide mechanism includes a welding step in which the second groove and the stopper are welded by resistance welding while the stopper is pressed against the second groove.

A welding assembly including a current generator, a first electrode electrically coupled to the current generator, the first electrode including a first engagement surface, a second electrode electrically coupled to the current generator, the second electrode including a second engagement surface, a width-determining fixture positioned between the first electrode and the second electrode to define a welding volume having a width, and an electrically nonconductive material positioned to electrically insulate at least one of the first electrode and the second electrode from an electrical conductor outside the width.
