Keystone information generating device used for welding process of sheet metal and method for generating key line information

摘要

Problem to be solved: to provide a sheet metal to be welded to a sheet metal of an object to be welded, and to provide an information processing apparatus for a welding process of sheet metal which can generate information for automatic marking of a keystone wire used for welding.The sheet metal shape data acquisition unit 111 acquires shape data of the first sheet metal and the second sheet metal to be welded.The marking surface information acquiring section 112 acquires information of the marking surface marking the kegare wire used for welding processing in the first sheet metal and the second sheet metal.The welding attribute information acquisition section 113 acquires welding attribute information concerning welding processing.When a welding instruction for welding the second sheet metal to the first sheet metal is obtained, the machining shape data generating section 114 generates machining shape data marking the keel line generated based on the welding attribute information on the marking surface in the shape data of the first sheet metal or the second sheet metal.Diagram
