Method for producing a piston for an internal combustion engine and piston produced by means of said method
Abstract:
A method for producing a piston may include aligning at least two piston components along corresponding joining surfaces, activating a laser designed for deep-welding, and aligning a laser beam with a starting point. The method may then include increasing a power density of the laser beam over a first defined path along the joining surfaces to produce a weld seam with an increasing weld seam depth, deep welding along the joining surfaces to produce a deep weld seam with a substantially constant weld seam depth up to a defined end point, and reducing the power density over a second defined path to produce a weld seam with a decreasing weld seam depth. The method may further include overwelding at least part of at least one of the first and second defined paths by a laser designed for heat conduction welding to produce at least one heat conduction weld seam.
