UNION BETWEEN THIN LAYERS IN THE FORM OF A STRIPE ONE PROPOSED ON OTHER DOUBLE OR MULTIPLE SURFACE, IN PARTICULAR BETWEEN TWO TAPES SUBJECT TO A CONTINUOUS TREATMENT.

摘要

Layers (10, 20) in the form of a strip of metallic material (11, 21), which are thin formed arranged on each other with double or multiple surface and are joined together by welding points (30), also presenting terminal sections (13, 23) that overlap each other in a region of overlap (15), in particular two tapes (10, 20) that can be rolled, which are subjected to continuous treatment in an installation that works continuously, such as a sheet rolling mill or an annealing furnace, characterized in that in the region of overlap (15) several weld points (30) pass in an annular form in themselves through the two layers of the tapes (10, 20) , because the annular welding points (30) are arranged at a distance (16, 27) from the front ends (17, 26) of the two tapes (10, 20), and because inside the ring (31) from the annular welding points (30) a hole (32) is burned in the belt material to (11, 21) of the two layers (10, 20), the metallic material (11, 21) of the two tapes (10, 20) being equally molten (35) in the walls that limit the hole (32) of the annular welding points.
