Patent Number Title Of Patent Date Issued
7555833 System for programmable self-piercing riveting July 7, 2009
A system and method for self-piercing riveting including an alignment mechanism comprising laser diodes and sensors for facilitating alignment of a rivet gun and a back-up located on opposite sides of sheet metal parts to be joined, and an oscillation piercing technique for reducing
7112757 Programmable resistance seam welding apparatus and method September 26, 2006
A resistance welding apparatus having a pair of programmable ball electrodes carried on universally movable positioners. The positioners are programmed to move the ball electrodes simultaneously along a seam line so that the ball electrodes clamp and support opposite sides of a pair
7060929 Sheet-to-tube resistance spot welding using servo gun June 13, 2006
A method of spot welding a sheet overlapped to a tube with a servomotor-driven electrode applying a clamping force to the sheet. Over a first clamping time interval, the clamping force is increased to a first force level, at which point a welding current is applied to weld the sheet
7001097 Tubular joint assembly February 21, 2006
A joint assembly for joining first and second tubular members. The first member has flanges extending from walls of an end segment. The walls of the end segment define a receiving opening. The second member has walls and a protrusion having sides extending from the walls to an end of the
6927357 Weld gun equalizer August 9, 2005
A weld gun having a linkage, which relates pivotal motion of a pair of laterally opposed facing electrodes of the weld gun in a predetermined manner. Based upon the predetermined motion of the electrodes a welding robot positions the electrodes of the weld gun on opposite sides of a
6870122 Electrode alignment inspector and method March 22, 2005
Method and apparatus for detecting unacceptable misalignment of welding electrodes. An electrode-alignment station is positioned adjacent a welding station. A robot controls the movement of the electrodes, and occasionally moves the electrodes out of the welding station and into an e
6688000 Joining of tubular parts in a T-joint by riveting/brazing February 10, 2004
In attempting to reduce deformity when joining vehicle frame components, a riveting/brazing process has been proposed. This process includes joining tubular members, such as hydroformed parts, by cutting at least one flange into one end of a first body member, shaped in conformance with
6646221 Method for repairing resistance spot welds in aluminum sheet materials November 11, 2003
A method for repairing resistance spot welds formed between joined pieces of aluminum alloy sheet metal, such as vehicle body parts. The repair method includes resistance welding where an existing undersized spot weld is enlarged by applying electric current flow through the aluminum all
6621036 Programmable pogo welding apparatus and method September 16, 2003
A pogo welding apparatus especially for spot welding metal sheets at selected locations spaced away from their edges wherein the sheets are held in a temporary assembly with the selected locations engaged and separate programmable positioners move a primary (pogo) electrode and a bac
6429397 Programmable pogo welding apparatus and method August 6, 2002
A pogo welding apparatus especially for spot welding metal sheets at selected locations spaced away from their edges wherein the sheets are held in a temporary assembly with the selected locations engaged and separate programmable positioners move a primary (pogo) electrode and a bac
