  • Hard-Soldering Method and Device
    Publication number: 20080272112
    Abstract: To hard-solder parts to be joined along a common joint, the parts are heated by a heat source e.g. a laser beam (3). Melted solder (7) that is stored in a container (6) is then introduced into the joint. Joints can be filled with solder in this manner at higher speed and the solidified solder surface is practically devoid of pores, thus permitting the priming or painting of said parts without the need for subsequent treatment.

  • Tailored tubular blanks and a method for the production thereof
    Publication number: 20050013954

  • Method and device for producing welded blanks
    Patent number: 6639176
    Abstract: For the manufacture of composite panels (16) it is proposed that they be held essentially upright by means of holding devices (17) and that welding by means of a laser welding plant (11, 13) be performed in this position. This affords a considerable space saving compared with the conventional horizontal arrangement in which the composite panels are processed and handled.

  • Method for producing a molded part and a molded part produced according to said method
    Patent number: 6394335
    Abstract: 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.

  • METHOD FOR PRODUCING A MOLDED PART AND A MOLDED PART PRODUCED ACCORDING TO SAID METHOD
    Publication number: 20010008228
    Abstract: The invention relates to a molded part (10) which is configured by initially forming a tubular body (2) with a soldered flange (7). Subsequently, the body (2) is shaped in a mold (8) by securing the flange (7) under high internal pressure to shape the form part or the preform (10). Thus, preforms with a secured flange that can be used to connect said preforms to other parts can be easily obtained.

  • Apparatus for butting two workpieces together for a welding operation
    Patent number: 6127646
    Abstract: 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.

  • Method and apparatus for connecting two workpieces together
    Patent number: 6105845
    Abstract: 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.

  • Method of producing and utilizing deformable workpieces for high-pressure forming and products formed thereby
    Patent number: 6070786
    Abstract: 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.

  • Method and apparatus for connecting two metallic workpieces together
    Patent number: 6053392
    Abstract: 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.

  • Method and apparatus for connecting two workpieces together
    Patent number: 6036075
    Abstract: In a method for connecting two workpieces together by welding, the workpieces are placed on clamping tables by a feed unit and are joined together by a welded seam. First, the workpieces are positioned in the feed unit. The feed unit is then traversed between the clamping tables and deposits the workpieces on them. Simultaneously with its feed movement, the unit expels the workpieces welded together in the preceding cycle.

  • Process and device for welding sheets by laser to form compound sheets
    Patent number: 5977511
    Abstract: 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.

  • Process and device for the posttreatment of welded compound panels
    Patent number: 5639012
    Abstract: In a compound panel welding line, the compound panels discharged from a welding machine are cooled by means of a cooling unit. In the cooling unit, the welded seam is treated with a cooling fluid, in particular a rust-preventative oil. This allows the panels to be cooled and oiled within a very short time and over a very short distance, thus substantially reducing the overall length of a welding line, and greatly facilitating the handling of the compound panels.
