A brazing process (100) and plate assembly are disclosed. The brazing process includes positioning a braze foil on a first workpiece (102), then securing the braze foil to the first workpiece to form a brazable component (104), then positioning a second workpiece proximal to the brazable component (106), and then brazing the second workpiece to the brazable component (108). Additionally or alternatively, the brazing process includes positioning the braze foil on a tube, then securing the braze foil to the tube to form a brazable tube, then positioning a plate of a plate assembly proximal to the brazable tube, and then brazing the plate to the brazable tube. The plate assembly includes a plate and a tube brazed to the plate by a braze foil secured to the tube.

Es sind eine Vorrichtung (110, 120, 130) und ein Verfahren zur Handhabung eines Fahrzeugmontagewerkzeugträgers (300) bei einer Fahrzeugfertigungslinie (1) sowie ein Fahrzeugmontagewerkzeugträger (300) und eine Montagestation (100) bereitgestellt. Die Vorrichtung (110, 120, 130) zur Handhabung eines Fahrzeugmontagewerkzeugträgers (300) bei einer Fahrzeugfertigungslinie (1) hat eine erste Handhabungseinrichtung (110) zur Handhabung des Fahrzeugmontagewerkzeugträgers (300), der mindestens zwei Tragflächen (300A, 300B) hat, die jeweils zum Tragen eines bei einer Montage eines Fahrzeugs (2) in der Fahrzeugfertigungslinie (1) zu verwendenden Fahrzeugmontagewerkzeugs (340, 360) ausgestaltet sind, und eine zweite Handhabungseinrichtung (120) zur Handhabung des Fahrzeugmontagewerkzeugträgers (300) gemeinsam mit der ersten Handhabungseinrichtung (120). Insbesondere sind die erste und zweite Handhabungseinrichtung (110, 120) zur gemeinsamen Handhabung des Fahrzeugmontagewerkzeugträgers (300) derart ausgestaltet, dass nach der Handhabung eine der mindestens zwei Tragflächen (300A, 300B) des Fahrzeugmontagewerkzeugträgers (300) an einer vorbestimmten Position (VP) angeordnet ist, an der sich zuvor eine andere der mindestens zwei Tragflächen (300A, 300B) befand.
摘要:
There is disclosed a method of manufacturing a rotor for a dynamoelectric machine. The rotor includes a rotating shaft, a rotor core fixed on the rotating shaft, and a cooling fan fixed to an axial end face of the rotor core. The method includes the step of fixing the cooling fan to the axial end face of the rotor core by resistance welding. The method is characterized in that in the resistance welding, both a positive electrode and a negative electrode are first brought into contact with the cooling fan to have the cooling fan held between the axial end face of the rotor core and both the positive and negative electrodes, and then weld current is supplied to flow from the positive electrode to the negative electrode.
摘要:
An object is to provide a welder optimum for use in strip metal rolling and to provide a metal rolling method including the most advantageous sequence for strip metal rolling in association with the welding and subsequent separation of a leader strip. [Means for Solving the Problem(s)] A welder for a metal rolling system 10 includes a back bar disposed below the pass line and welding guns disposed above the pass line to perform series welding for welding a plurality of points at one time. A method according to the present invention includes connecting a leader strip L held by the winder 4 on the delivery side to a front end portion of a product strip A by a spot-welder 10, and finishing the rolling of the product strip A by an even ordinal number pass toward the winder 3 on the entry side.
摘要:
The aim of the invention is to provide a method for producing a largely flat component assembly (1) of a motor vehicle body, having an inner part (2), and outer part (3), and at least one reinforcement part (4) disposed therebetween, said method improving on conventional methods by advantageously combining a reduced production expense per se and a reduced heat input, particularly into the steel of a press-hardened component. The aim is achieved substantially in that the inner part (2) is first fixed to the reinforcement part (4) in the region of attachment flanges (5, 7) corresponding to one another by resistance spot welding (12) to form a weld group (11) and the outer part (3) is subsequently placed on the weld group (11) thus created in the region of said attachment flange (5, 7) and is attached thereto in a fixed manner at least in critical crash-relevant flange sections (15) by resistance projection welding (14).

Die Erfindung bezieht sich auf ein Verfahren zum Positionieren und Fügen von Karosserieteilen (1,2) einer Fahrzeugkarosserie mit folgenden Schritten: - Bereitstellen eines ersten Karosserieteils (1), das mindestens ein Formschlusselement (3) aufweist, - Bereitstellen eines zweiten Karosserieteils (2), das mindestens ein mit dem Formschlusselement (3) des ersten Karosserieteils (1) zusammenwirkendes Formschlusselement (4) aufweist, - Aneinandersetzen der beiden Karosserieteile (1,2), so dass die Formschlusselemente (3,4) ineinander eingreifen und die beiden Karosserieteile (1,2) zumindest in bestimmten Richtungen gegen Verrutschen sichern und in einer vorgegebenen SolI-Position halten, - Dauerhaftes Verbinden der beiden Karosserieteile.
摘要:
The system allows welding of a hollow tube (2) on the window post (3) on one side of the body shell of a motor vehicle without reflecting the welding efforts on the welding system's support. The welding system comprises a support (10) on which is mounted in a mobile way a support mass (11) and an electrode (12). A support element (16) is fixed in relation to a support (10), through an effort retrieving means (14) and placed facing the electrode (12), so as to be able to rest on an opposite surface of two parts to be welded (2, 3). The support mass (11) is mobile in translation, in the same way as the movement of the electrode (12), so as to rest against the welding set. The present invention can be used to weld the window post of one side of the body shell of a motor vehicle.
