A conductive cell frame for connecting a plurality of battery cells is disclosed. The conductive cell frame includes a first conductive portion and a plurality of second conductive portions, and the upper surface of each second conductive portion is connected to the first conductive portion through a eutectic portion. The lower surface of each second conductive portion is provided with at least one protruding welding portion, wherein the second conductive portion is connected to the housing of the battery cell through the protruding welding portion. The first conductive portion and the second conductive portion are made of different materials, wherein the resistance of the second conductive portion is greater than the resistance of the first conductive portion. Thus, a small current can be used to connect to the conductive cell frame and the battery cell, which not only reduces the consumption of energy, but also avoids damage of the battery cell during the electric welding process

A torque converter includes a cover having a first surface and an annular plate axially spaced from the cover and having a second surface facing the first surface. A disc of the torque converter is disposed between the cover and the plate and has opposing first and second faces adjacent to the first and second surfaces, respectfully. Each of the faces defines a projection joined to one of the first and second surfaces by at least one capacitive discharge weld.

A sheet metal bearing cage segment includes a first ring section, at least one second ring section, and a plurality of bridges connecting the first and second ring sections to each other and defining a plurality of pockets between the bridges. The bearing cage segment includes first and second circumferentially directed joint edges, the first joint edge is configured to connect to the second joint edge of the bearing cage segment or to a second joint edge of another sheet metal bearing cage segment, and the first joint edge includes at least one body of welding material projecting from the joint edge. The body of welding material may be pressed against the second joint edge while leaving a gap between the joint edges, and the welding material can be liquified by a resistance welding process to connect the joint edges.

A feeding rod is configured to insert a shaft-shaped component having a circular flange and a shaft portion into a receiving hole. A central axis of the shaft portion is disposed in an inclined state with respect to a central axis of the receiving hole due to the inclined disposition of the feeding rod. A surface of the flange is in close contact with a tip surface of the feeding rod due to an attraction force of a magnet of the feeding rod. A positioning protrusion receives an outer peripheral portion of the flange and sets a relative position between the feeding rod and the shaft-shaped component. A most advanced stop position of the feeding rod is a position where a tip portion of the shaft portion has entered the receiving hole, and the attraction force of the magnet is configured to be eliminated at the stop position.

A bonded body includes a first metal piece, a second metal piece, and a spacer. The first metal piece has a first surface and a protrusion protruding on the first surface. The second metal piece has a second surface, and the second surface of the second metal piece is bonded to the first surface of the first metal piece at the protrusion. The spacer has an electrically insulating property. The spacer is provided on the first surface of the first metal piece, and located between the first metal piece and the second metal piece. The first metal piece and the second metal piece are arranged to face each other such that a portion of the first surface of the first metal piece outside of the spacer is exposed from the second metal piece.

A method for the connection of components or component regions and a non-releasable connection produced in this manner. Two connection faces are partially welded to each other with an adhesive layer being incorporated between the two connection faces. The method including the following steps: arranging a welding base on a connection face, applying the adhesive layer to a connection face, moving the connection faces toward each other in such a manner that the welding base is applied against the other connection face, introducing welding current in the region of the applied welding base. A spacer is arranged between the connection faces before the connection faces are moved toward each other. The connection faces are spaced apart from each other in the region of the welding base by the extent that the welding base projects above the spacer.

The invention relates to a method of welding of at least two metal-based materials (5, 7), non-weldable directly to each other with resistance welding. At least one spacer (6) is joined by welding on at least one of the two surfaces of a material (5) in every interstice between two surfaces of materials to be welded. The welded spacer (6) is utilized so that resistance welding is focused to the surface of the material (5) with the spacer (6) to melt at least one spacer (6) located on the heat affecting zone in order to achieve a weld between the metal-based materials (5, 7).
