Welding path information acquisition method and welding robot system

摘要

A method of acquiring welding path information about the construction conditions of a welding path for welding two workpieces to be welded by a welding robot, comprising: extracting a welding path for welding two workpieces from three-dimensional CAD data, and a predetermined three-dimensional shape Preparing a wall surface determination model having, and arranging the wall surface determination model in an extension direction toward the outside of the welding path based on the welding end that is at least one of the starting point or the ending point of the welding path, and placing For one wall surface determination model, a step of determining whether a wall surface defined by another member different from the two work pieces interferes.
