摘要:
To form a body, a preform is produced by welding together two essentially flat sheet-metal blanks at their margins. This preform is then deformed in a mold by internal high-pressure forming to produce the desired body. In this way, complex metal bodies can easily be formed.
摘要:
The invention relates to a molded part which is configured by initially forming a tubular body with a welded flange. Subsequently, the body is shaped in a mold placing the body under internal pressure to form a part or preform. Thus, preforms with a welded flange can be obtained and connectedn with other parts.

To form a body, a preform is produced by welding together two essentially flat sheet-metal blanks (2,3) at their margins. This preform is then deformed in a mold by internal high-pressure forming to produce the desired body. In this way, complex metal bodies can easily be formed.
摘要:
The sheets which are to be butt welded are positioned with their edges in contact with one another. To reduce the gap to a width acceptable for laser welding, at least one sheet is plastically deformed along the line of the joint so that material flows towards the gap, reducing the width of the gap. In this way, sheets cut to size with much less precision can be welded together.

The sheets (1,2) which are to be butt welded are positioned with their edges in contact with one another. To reduce the gap (3) to a width acceptable for laser welding, at least one sheet (2) is plastically deformed along the line of the joint so that material flows towards the gap, reducing the width of the gap. In this way, sheets cut to size with much less precision can be welded together.

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.

A rupturable can member (10) of sheet metal has a pair of scorings (16) which define a tearing strip (18) laterally. Welded onto the tearing strip (18) is a tongue (20), which has a thickened portion (24) at its welded-on end (22). This thickened portion is formed by a margin folded back towards the other free end (26) of the tongue (20).
摘要:
In the case of the hard-soldering or the welding of joint parts (1,2) which form a notch shaped joint (3), an insert (4) is introduced and soldered or welded in place. As a result, a joint closure is obtained which can be coated without subsequent processing.
摘要:
To make tailored tubular blanks the circumferential weld seam and the longitudinal weld seam are so arranged that the seams do not intersect but only form an interface. In this way tailored tubular blanks that have better formability are produced.
