US Patent:

6346684, Feb 12, 2002

Filed:

Mar 3, 2000

Appl. No.:

09/518646

Inventors:

Gianfranco Gabbianelli - Troy MI
Ralph Miller - Sterling Heights MI

Assignee:

Cosma International Inc. - Concord

International Classification:

B23K 1100

US Classification:

2191171, 219 60 A, 219 602, 298972, 296 29

Abstract:

A welding material assembly is constructed and arranged to position a welding material in electrically conductive relation between exterior surface portions of first and second weldable members at a location where the first and second weldable members are to be joined. The welding material assembly includes at least one welding material member mounted on a flexible carrier sheet in a predetermined arrangement, each welding material member being constructed of an electrically conductive metallic welding material capable of melting when heated by application of an electrical current and each carrier sheet being constructed of a material that is electrically nonconductive. Each welding material member is mounted on the sheet such that when the sheet is placed between the exterior surfaces of said first and second weldable members to be welded each said welding material member is electrically conductively disposed therebetween.

International Classification:

G06F 1546

US Classification:

364474

Abstract:

A sturdy three-dimensional master model constructed using CAD/CAM and N/C machine tool techniques by digitally processing surface data to obtain low density, unsweetened, template contour lines offset below the surface on an axis normal thereto, and then simultaneously constructing a rough model having a surface offset above the surface on an axis normal thereto, while developing the surface data to sweetened, high density cutter path data and then using the cutter path data to N/C mill the rough plus model.
