In a method for connecting two workpieces together by welding, the workpieces are placed on clamping tables by a feed unit (F) and are joined together by a welded seam. First, the workpieces are positioned in the feed unit (F). The feed unit (F) is then traversed between the clamping tables and deposits the workpieces on them. Simultaneously with its feed movement, the unit (F) expels the workpieces welded together in the preceding cycle.

In a method for connecting two workpieces together by a welded seam, the workpieces are held in a welding station between opposed tracks consisting of a plurality of members. The tracks run around guide rollers in a conveying direction. A clearance (a) between the guide rollers which come first in the conveying direction can be changed upon insertion of the workpieces between the tracks.

In an apparatus for connecting two workpieces together by welding, the workpieces lie on supporting surfaces and are butted together at their edges to form a butt joint. The workpieces are subjected to pressure on the side opposite to the supporting surfaces. At least one supporting surface is capable of yielding under pressure, and, in so doing, changes its position in relation to the butt joint, so as to reduce any gap between the workpieces.

In a process for joining two metallic workpieces together, the pieces are butted together to form a butt joint and are joined to one another in the region of the butt joint. During this operation, the workpieces are subjected to a magnetic attraction force at one side, and. can be subjected to holddown pressure on the opposite side.

In an apparatus for connecting two workpieces (1) together by a welded seam, the workpieces are held in a welding station between opposed tracks consisting of a plurality of members. The tracks run around guide rollers in a conveying direction. A clearance (a) between the guide rollers which come first in the conveying direction can be changed upon insertion of the workpieces between the tracks.

In a process for joining two metallic workpieces (1.1,1.2) together, the pieces are butted together to form a butt joint (2) and are joined to one another in the region of the butt joint (2). During this operation, the workpieces (1.1,1.2) are subjected to a magnetic attraction force at one side, and can be subjected to holddown pressure on the opposite side.

The invention relates to a universal joint comprising two joint yokes and a cross member. One of the joint yokes is connected to a driven shaft or drive shaft, the other joint yoke being connectable or connected to the shaft to be driven or driven shaft. The two joint yokes are arranged twisted radially at an angle of 90° in relation to each other so that the two joint yokes form an internal space, in which the cross member is disposed. The cross member is formed of two separate pin bearers arranged orthogonally in relation to each other which are pivoted in the respectively associated joint yokes. The pin bearers crossing each other are rigidly connected with each other. The pin bearers with their pins that are arranged, respectively, at the end sides are pivoted in the associated joint yoke or in its yoke arms via bearings. The radially opposing bearings of the respective joint yoke form a pair of bearings, respectively. One insulation element, respectively, is associated with at least one of the pairs of bearings or with the respective bearing of the at least one pair of bearings, so that the at least one pair of bearings has a pair of insulation elements.

The invention relates to a universal joint comprising two joint yokes. One of the joint yokes is connected to a driven shaft or drive shaft, the other joint yoke being connectable or connected to the shaft to be driven or driven shaft. The two joint yokes are arranged twisted radially at an angle of 90° in relation to each other so that the two joint yokes form an internal space. An elastic coupling element is associated with the universal joint. One of the joint yokes or its yoke arms is associated with a pin bearer, the other joint yoke or its yoke arms being associated with a holding element. Both the pin bearer as well as the respective holding element is pivoted in bearings respectively disposed in the joint yokes. The pin bearer and the holding element are spatially separated from one another and connected via the elastic coupling element.
