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 conductively 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).
