B23K 31/02
US Classification:

228102, 228103, 228105, 228175, 228212
Abstract:

A system for automated assembly and welding is disclosed. The system includes a pallet for receiving incoming workpieces; a workpiece holder having a plurality of electromagnets; a handling robot configured to transport incoming workpieces from the pallet to the workpiece holder; and a controller in communication with the workpiece holder and the handling robot. The controller is configured to determine an orientation of a workpiece positioned on the workpiece holder, and to selectively adjust an activation state of one or more electromagnets of the workpiece holder based upon the orientation of the workpiece. A method of assembling and welding workpieces is also disclosed.

US Patent:

20130240490, Sep 19, 2013
Filed:

Mar 15, 2012
Appl. No.:

13/421043
Inventors:

Huijun Wang - Peoria IL, US
Howard W. Ludewig - Groveland IL, US
Keith M. Egland - Peoria IL, US
Glenn A. Forthofer - Metamora IL, US
Assignee:

Caterpillar Inc. - Peoria IL
International Classification:

B23K 26/00
US Classification:

2191216
Abstract:

A tack welding method for use with a hybrid laser arc welding process. The method provides a recess on an edge of a first piece. The edge of the first piece is configured to cooperate with a second piece. The method positions the first piece relative to the second piece so as to provide a gap between the first piece and the second piece. Subsequently, the method provides a tack weld within the recess of the first piece. The recess is configured to accommodate placing the tack weld at a root of the gap.

Timothy W. Olmsted - Dunlap IL, US
Assignee:

Caterpillar Inc. - Peoria IL
International Classification:

B23K 33/00
B23K 31/00
Abstract:

A structural member includes a body having a first surface, a second surface, and an end surface at an end portion of the structural member. The end portion of the structural member includes a root protrusion extending radially outward from the second surface of the structural member along a root protrusion radius to an outer end of the root protrusion to define a root protrusion height extending from the second surface of the structural member to the outer end of the root protrusion. The root protrusion further includes a root protrusion width extending between an inner edge and an outer edge of the outer end of the root protrusion. The root protrusion radius, the root protrusion height, and the root protrusion width are configured to define a stress protected weld root region isolated beyond and away from a root stress flow path propagated through the body of the structural member.
