Abstract

This invention relates to a method for determining misalignment of a powder feed nozzle and a laser beam. The method includes forming a test structure on a workpiece in at least two different directions by deposition laser welding with powder at substantially constant deposition parameters without relative rotation between a powder feed nozzle and a laser beam, measuring heights and/or wall thicknesses of the test structure along the test structure, and determining a direction and/or an amount of misalignment of the powder feed nozzle relative to the laser beam based on the measured heights and/or wall thicknesses.
