US 6,281,467 B1 · Conductive heat resistance seam welding

Abstract

A welding arrangement (10) consists of first and second parts to be welded (4a, 4b) with a portion of the first part and a portion of the second part juxtaposed to form a weld zone (8a, 8b). An electrically-conductive sheet (2) with a higher melting temperature than a melting temperature of the first part (4a) and a melting temperature of the second part (4b) is placed over the weld zone (8a, 8b). A first electrode (12) is placed in contact with the electrically conductive sheet material (2) and a second electrode (14) is positioned and aligned with the first electrode (12) to heat conducively the weld zone (8a, 8b) with an electrical current. For the butt weld configuration (10), a second electrically conductive sheet (6) is placed between the second electrode (14) and the weld zone (8a, 8b).

Dependent claims

A welding arrangement comprising:

a) a first part;
b) a second part;
c) a portion of said first part and a portion of said second part juxtaposed one to the next to form a weld zone;
d) resistively heated and electrically-conductive sheet material, said sheet material consisting of a single sheet, said single sheet:
1) having a higher melting temperature than a melting temperature of said first part and a melting temperature of said second part,
2) placed on a first side of said weld zone, and
3) conductively heating said weld zone to weld said first part and said second part together;
e) a first electrode placed in contact with said single sheet;
f) a second electrode positioned and aligned with said first electrode to heat resistively said single sheet with an electrical current with subsequent conductive heating of said weld zone to produce sufficient heat to weld said first part and said second part together.
