PURPOSE:To facilitate unmanned welding work by converting drawing information of an object to be welded to numerical data to prepare teaching data, and inputting it to a storage device of a welding robot. CONSTITUTION:An object to be welded is placed at a specified position to a welding robot 6. Drawing information 1 of the object is converted to numerical data and numerical data of a weld line are prepared. The numerical data 2 are converted to coordinate numerical data 4 by an offline computer 3. The coordinate axes are compared with actual coordinate axes that indicate a specified part of the object, and coordinate conversion in performed to convert the data to coordinate numerical data set to coordinate axes of the offline computer 3 and coordinate numerical data that coincide relatively to actual coordinate axes. The processed data are inputted to a storage device of the welding robot 6 as three-dimensional data of weld line of the object to be welded to complete teaching. |
