| PURPOSE:To obtain sufficient welding strength by providing a raised part or recess to each of a base plate and a contact point material, fitting and tentatively fixing these and irradiating laser light to the fitted parts. CONSTITUTION:At least a raised part 5 or recess 6 is provided to a base plate 2, and a recess 7 or raised part 8 in correspondence to this is provided to a contact point material. This material 1 is fitted to the base plate 2 by fitting the raised part 5 or recess 6 to the recess 7 or raised part 8 or fitting both and these are tentatively fixed. Thence, laser light 4 is irradiated from the side face of the fitted parts, whereby said parts are welded. Since in this method the laser light 4 is irradiated to the parts where the base plate 2 and the material 1 superpose, the laser welding having sufficient strength is accomplished. | ||||||

| PURPOSE:To obtain a satisfactory adhesive property of a free end edge part of a thin plate and a base plate, and to form a uniform welding state, by curving the thin plate, pressing both the end edge parts against the base plate, and welding by irradiation of a laser beam, when welding one end edge of the thin plate on the base plate. CONSTITUTION:One base plate 3 to be welded is fitted into a receiving groove 2 of a base stand 1, on which a springy thin plate 4 to be welded is placed. The thin plate 4 is positioned by fitting a pin 6 provided on the base stand 1 into a hole 5 of the thin plate 4, and also the thin plate 4 is curved upward in the projecting shape. The thin plate 4 is pressed by pressing parts 8a, 8b on both sides of the lower part of a pressing block 8, and a place around a welding point A of the thin plate 4 and a place around a free end edge part of its opposite side are pressed and fixed by force of a spring plate 9. Subsequently, the thin plate 4 is welded to the base plate 3 by heating the welding part A by a laser beam irradiating device 11. The thin plate 4 does not float up from the base plate 3 as a contact part of a relay switch, and a contact member having a satisfactorily close contact state is obtained. | ||||||

| PURPOSE:To produce an electric contactor having less damages of arc-resistant metal by forming a base metal and the arc-resistant metal part to one body by the use of a high-density energy source. CONSTITUTION:After powder of tungsten and copper is sprayed to an electricity- conducting part 1 produced of pure copper or copper alloy of high conductivity, a heat source 3 of high-density energy, for example, electron beam or laser beam is irradiated to melt part of the electricity-conducting part and the powdery tungsten and copper, thereby producing an arc-resistant metallic part. Since the arc-resistant metallic part and the electricity-conducting part are melted and joined in one body by the high-density energy heat source, the damage in the joining part owing to the heat of the arc generated at the opening and closing of current of large capacity is less and the function as a switching device is maintained. | ||||||

| A method for mutually welding a plate that has at least one layer based on Ag alloys and a copper body, comprising the use of laser means for performing the welding, its particularity consisting of the fact that it comprises the steps that consist in: -- superimposing and coupling one face of the plate on a surface of the copper body; -- starting the welding process by focusing the laser means on a point located proximate to the joint between the face of the plate and the surface of the copper body; -- maintaining an angle of incidence of the laser means at values other than 0° with respect to the perpendicular to the surface to be welded; -- moving the laser means with respect to the joint, so that the weldpool is pushed along the joint. | ||||||

Die Erfindung betrifft ein Verfahren zur partiellen stofflichen Verbindung von Bauteilen mit schmelzbaren Materialien. Es wird die Aufgabe gelöst, ein solches Verfahren zu schaffen, mit dem eine Vielzahl von Kontakten und ähnlichen Beschichtungen aus schmelzbaren Materialien mit geringem Zeit- sowie Materialaufwand und dadurch kostengünstig mittels Laserstrahl auf Bauteilen ausgebildet werden können. Dies wird dadurch erreicht, dass das auf das Bauteil aufzubringende schmelzbare Material als ein Pulver ausgestaltet ist, wobei dieses Pulver Bestandteil eines pastösen Materialgemenges ist, das neben dem Pulver zumindest ein Bindemittel aufweist, wobei das Materialgemenge nach dem partiellen Auftragen auf das Bauteil durch Zufuhr von Energie aus dem pastösen Zustand, ohne dass die Bindungskräfte innerhalb des Materialgemenges aufgehoben werden, in einen festen Zustand überführt wird und auf der Oberfläche des Bauteiles verbleibt und wobei nachfolgend nur der Pulveranteil des Materialgemenges mittels Laserstrahl mit dem Bauteil stofflich verbunden wird. |

| The invention relates to a method for welding two welding parts (1, 3) by means of a fillet weld (11), wherein a first welding part (1), with a bearing surface at least in an edge area of an edge that is to be welded by means of a fillet weld, is brought into contact with a bearing surface of a welding part (3) and the welding energy (5) is supplied in an energy supply area during the welding process, exclusive of a surface (7) of the first welding part facing away from the bearing surface, said energy supply area being located at a predetermined distance from the edge of the first welding part. The welding energy is supplied in a direction, whereby the direction component thereof points perpendicular to the course of the fillet weld that is to be produced in the direction of an inner area of the first welding part, forming a welding angle of less than 90° with the contact plane of the bearing surfaces of the first and second welding parts. The welding energy is supplied until at least the energy supply area of the first welding part and a sufficient area of the second part, which is adjacent to the energy supply area of the first welding part, and also the material supply area located between the energy supply area and the edge of the first welding part are melted and fused together. The invention also relates to a welding part for carrying out said method and to an electric component with a printed conductor, which is welded to a cooling body of at least one power semiconductor element. | ||||||

A electromagnetic relay includes a spool, a coil, a U-shaped yoke, an armature, a movable contact, a pair of stationary contacts, and a taper. The spool has an inner hole and first and second flange portions formed at its two ends. The coil is wound on the spool. The yoke is locked at the flange portions of the spool by press fitting to stride over the coil. The armature is movably connected to one end of the yoke and positioned to extend through the inner hole of the spool. The movable contact is attached to move in an interlocked manner with the armature. The pair of stationary contacts are arranged to sandwich the movable contact. The taper is formed on at least one of press-fit locking surfaces of one end of the yoke and the first flange portion, and has a locking force that increases as being closer to a vicinity of the inner hole of the spool. A method of adjusting an electromagnetic relay, and a method of assembling an electromagnetic relay are also disclosed. |
