Publication number: 20100176093Abstract: The invention relates to a method of short-time stud joining, a first workpiece, such as a stud for example, being joined with its end face onto a joining surface of a second workpiece, such as a metal sheet for example, with the steps of: a) creating an arc between the end face and the joining surface in order to begin melting the end face and/or the joining surface, and b) lowering the first workpiece onto the second workpiece and switching off a joining current (Is), so that the melt cools down and a rigidly joined connection is obtained between the first and second workpieces. In this case, the first workpiece is advanced at least once in the direction of the second workpiece between steps a) and b), in order to achieve an interim short-circuit of the arc, and is subsequently withdrawn again, in order once again to draw an arc.Type: ApplicationFiled: February 8, 2010Publication date: July 15, 2010Applicant: NEWFREY LLCInventor: Klaus-Gisbert SCHMITT

Publication number: 20100096366Abstract: A joining device for joining a component to a workpiece. The device includes a component holder which moves the component along an axis in a first direction towards the workpiece in order to connect the component to the workpiece, and has a protective gas feed in order to carry out a welding process in a protective gas atmosphere. During the welding process the protective gas is discharged essentially in a second direction which is opposed to the first direction. An elastic sealing sleeve including folding bellows is arranged in relation to the component holder in such a way that a welding space, which is bounded by the workpiece, the component holder, the component and the sealing sleeve and through which the protective gas flows, is sealed off from the external surroundings during the welding process so that the protective gas can escape only in the second direction.Type: ApplicationFiled: November 18, 2009Publication date: April 22, 2010Applicant: NEWFREY LLCInventors: Klaus-Gisbert SCHMITT, Wolfgang DOKUPIL, Lothar GERLACH, Michael SCHNEIDER
