The welding process by overlapping with a beam of high energy density and overlap welding device with a beam of high energy density

摘要

"The process of welding by overlapping with a beam of high energy density and overlap welding device with a beam of high energy density.The present invention relates to a process for overlap welding with a beam of high energy density (11) of two plates (1, 2) coated.Characterized by the fact of split the beam (11) in a first sub beam (12) by crossing the two coated sheets (1, 2), and in that area a first bath of molten metal (18).And a second sub beam (13) and a second band-pass shape bath of molten metal (19) whose depth is less than the thickness of the plate coated with upper (1) and overlaps at least a part DThe molten metal bath (18) to facilitate the escape of steam from the coating material.And the fact is run on the second bath of molten metal (19) a neutral high speed gas jet ejection to form a chute (22) on the surface of the second molten metal bath.
