There is provided a spot welding apparatus. The spot welding apparatus includes a fixed electrode and a movable electrode that clamp and press a workpiece formed of stacked plates of different rigidities, and a control pressing force applicator that causes a control pressing force applying actuator to bring a receiving unit provided at a distal end of a control pressing force applying arm into contact with the workpiece so as to apply a control pressing force to the workpiece. The control pressing force applying arm is made of a non-magnetic material.

A method for fixing on a metal workpiece a connecting element permits the friction-increasing, play-free, reversible connection of workpieces to be joined. The connecting element includes a metal foil which bears on its joining surfaces hard material particles, which are fixed on the metal foil by means of a metallic binder phase. The connecting element is fixed on the metal workpiece securely for purposes of assembly and transportation by welding involving the formation of locally confined weld points. Alternatively a component includes a metal workpiece and a connecting element fixed on it securely for purposes of assembly and transportation by locally confined weld points. The connecting element permits the friction-increasing, play-free, reversible connection of workpieces to be joined and includes a metal foil which bears on its joining surfaces hard material particles, which are fixed on the metal foil by means of a metallic binder phase.

Provided herein is a method for securely fixing a connecting element on a metal workpiece by welding involving the formation of locally confined weld points that permits the friction-increasing, play-free, reversible connection of joined workpieces for applications in assembly and transportation. The connecting element includes a metal foil having hard material particles fixed on the joining surfaces by a metallic binding layer. Similarly, a component having a metal workpiece and the connecting element, which is suitable for the connection of workpieces to be joined in machine, plant, and motor vehicle construction, is also provided.

A golf club head manufacturing method, including: welding a first reinforcing piece with first thickness to a central portion between a toe and a heel, so as to extend along an edge of a face side of a sole part, the sole part being part of a lower part formed integrally with a side part; welding a second reinforcing piece of second, larger thickness to a central portion between the toe and heel so as to extend along the edge on the face side of the first piece; welding a face part to the first and second pieces from an inner space of the lower part; welding a hosel part to the lower and face parts; welding a crown part to the lower, face and hosel parts; and welding the lower and face parts together from the outside.
摘要:
A battery terminal strip for connecting to a terminal of at least one battery cell where the battery terminal strip includes four weld points formed in a strip of metal for each battery cell. Each of the weld points has a protrusion on a first surface of the strip of metal such that the protrusion contacts a terminal of the battery cell. The result is an air gap between the first surface of the strip of metal and the terminal of the battery cell. The air gap reduces heat transfer from the strip of metal to the battery during welding. A cross-cut is formed/cut in the strip of metal. Each segment of the cross-cut creates a gap in the strip of metal such that each gap is between two different weld points of the four weld points.

An application for a battery terminal strip for connecting to a terminal of at least one battery cell describes a battery terminal strip that is a strip of metal that has at least one weld point formed in the strip of metal. Each of the weld points having a protrusion on a first surface of the strip of metal such that the protrusion contacts a terminal of a battery cell of the at least one battery cell thereby forming an air gap between the first surface of the strip of metal and the terminal of the battery cell, thereby reducing heat transfer from the strip of metal to the battery during welding.

The invention relates to a method for fixing on a metal workpiece a connecting element which permits the friction-increasing, play-free, reversible connection of workpieces to be joined, the connecting element comprising a metal foil which bears on its joining surfaces hard material particles, which are fixed on the metal foil by means of a metallic binder phase, characterized in that the connecting element is fixed on the metal workpiece securely for purposes of assembly and transportation by welding involving the formation of locally confined weld points.The invention similarly relates to a component, comprising a metal workpiece and a connecting element fixed on it securely for purposes of assembly and transportation by locally confined weld points, the connecting element permitting the friction-increasing, play-free, reversible connection of workpieces to be joined and comprising a metal foil which bears on its joining surfaces hard material particles, which are fixed on the metal foil by means of a metallic binder phase.The components according to the invention are suitable for the non-positive, friction-increasing, play-free, reversible connection of workpieces to be joined in machine, plant and motor vehicle construction.
摘要:
A connection method for connecting an end of a signal wire (53) of a cable (51) to the connecting face of a contact (59) of a connector (52). The lengthwise direction of the connecting face of the contact (59) and the lengthwise direction of the signal wire (53) are mutually matched in connection. The end of the signal wire (53) is pressured against the connecting part by a pair of electrodes (69A, 69B) disposed in mutual separation in the lengthwise direction of the signal wire (53), and an electric current is passed between the pair of electrodes (69A, 69B). Thereby, the end of the cable (51) and the connecting part are mutually welded.
摘要:
A weld joins a thin overlay of low carbon steel to a base that contains high carbon steel, at least at its surface along which the weld is formed. The weld may be effected by fusion (melting) or by solid-state diffusion. With either it creates a heat affected zone (HAZ) in the base around the weld. The HAZ contains enough austenite, and perhaps bainite as well, to render the HAZ relatively ductile and also crack resistant. Adjacent to the weld the HAZ has a hardness that does not exceed 58 HRC. The weld may be produced with a high energy beam or with resistance welding equipment.
