摘要： A method for creating a welded steel part includes providing a first steel plate having a first base, a first intermetallic alloy layer on the first base and a first metal alloy layer on the first intermetallic alloy layer; providing a second steel plate having a second base, a second intermetallic alloy layer on the second base and a second metal alloy layer on the second intermetallic alloy layer; butt welding the first and second steel plates at a weld so as to melt material from at least the first base, the first intermetallic alloy layer, the second base and the second intermetallic layer to form a molten weld material; austenizing the welded steel plates at a temperature between Ac1 and Ac3+100 degrees C. for a time greater than or equal to 20 seconds; and cooling the welded steel plates so as to render a uniform microstructure to the weld.

摘要： The present invention provides a method for the preparation of steel sheets to be fabricated into a welded steel blank. The method includes procuring at least one pre-coated first steel sheet and one pre-coated second steel sheet, made up of a steel substrate and a pre-coating made up of an intermetallic alloy layer in contact with the steel substrate, topped by a layer of aluminum metal or aluminum alloy or aluminum-based alloy, the first sheet having a principal face, an opposite principal face, and at least one secondary face, the second sheet having a principal face, an opposite principal face and at least one secondary face, positioning the first and second sheets, leaving a gap of between 0.02 and 2 mm between the secondary faces and facing each other, the mating of the first and second sheets defining a median plane perpendicular to the principal faces of the first sheet and the second sheet, then removing the layers of metal alloy by melting and vaporization simultaneously on the principal faces, in a peripheral zone of the sheets, the peripheral zones being the zones of the principal faces closest in relation to the median plane located one on either side of it.

摘要： A method of butt-welding steel plates is provided. The method includes the steps of coating a first steel plate by dipping the first steel plate in a molten bath to obtain a first precoat upon the first steel plate. The first precoat includes a first intermetallic alloy layer and a first metal alloy layer, the first intermetallic alloy layer is topped by the first metal alloy layer. On a first face of the first steel plate, the first metal alloy layer is removed in a first area at a first periphery of the first steel plate, while at least part of the first intermetallic alloy layer in the first area remains. A second steel plate is coated by dipping the second steel plate in the molten bath or a further molten bath to obtain a second precoat upon the second steel plate. The second precoat includes a second intermetallic alloy layer and a second metal alloy layer, the second intermetallic alloy layer is topped by the second metal alloy layer. On a second face of the second steel plate, the second metal alloy layer is removed in a second area at a second periphery of the second metal plate. While at least part of the second intermetallic alloy layer in the second area remains. After removal of the first and second metal alloy layers, the first periphery of the first steel plate is butt-welded to the second periphery of the second steel plate to form a welded blank.
