Patent number: 10843285Abstract: A welding device for welding a workpiece using a welding robot includes a welding control device that controls operation of the welding robot and a preheating device that preheats the workpiece. The welding control device includes an input unit through which at least one or both of dimensions of the workpiece and a shape of a welding joint, and preheating information are inputted, and a storage unit that includes at least welding robot operation orbit teaching data, welding condition data, and preheating condition data. The welding control device automatically provides a preheating condition, a welding robot operation orbit, and a welding condition for the welding joint to be welded, and preheating and welding are performed.Type: GrantFiled: July 18, 2017Date of Patent: November 24, 2020Assignee: Kobe Steel, Ltd.Inventors: Hirohisa Kishikawa, Shun Izutani, Shigeto Takada, Hiroshi Matsumura

Patent number: 10843286Abstract: A welding device for automatically welding a workpiece by a welding robot using a welding wire includes a welding control device that controls operation and welding work of the welding robot. The welding control device includes a sensing unit configured to detect a position of the workpiece, a root gap calculating unit configured to determine a root gap, and a storage unit including wire melting information as a database of a proper welding current corresponding to a feeding rate for each of the welding wire. A lamination pattern and a welding condition are provided in accordance with the root gap determined by the root gap calculating unit and the wire melting information so that an amount of heat input is equal to or less than a predetermined amount of heat input.Type: GrantFiled: July 18, 2017Date of Patent: November 24, 2020Assignee: Kobe Steel, Ltd.Inventors: Hirohisa Kishikawa, Hiroshi Matsumura, Shigeto Takada, Kenji Sadahiro, Shun Izutani
