Abstract
A method for laser welding is provided. The method includes arranging at least one heat source point from a first collection of heat source points so as to overlap at least a portion of at least one heat source point from a second collection of heat source points, irradiating a portion of a target with the first and second collections of heat source points, the heat source points maintaining a linear profile within their respective collection, and directing the at least two collections of heat source points in a travel direction along a weld line, each linear profile maintaining an oblique angle relative to the travel direction.
Claims18
A method for laser welding, comprising:
- arranging at least one heat source point from a first collection of heat source points so as to overlap at least a portion of at least one heat source point from a second collection of heat source points;
- irradiating a portion of a target with the first and second collections of heat source points, the heat source points maintaining a linear profile within their respective collection;
- and
- directing the at least two collections of heat source points in a travel direction along a weld line, each linear profile maintaining an oblique angle relative to the travel direction.
10-17. (canceled)
A laser welding system, comprising:
- a laser source configured to produce a laser beam;
- a plurality of beam modifiers, each beam modifier of the plurality of beam modifiers being configured to split the laser beam to generate a collection of heat source points from the laser beam, the heat source points of each collection maintaining a linear profile;
- and
- one or more optical elements configured to direct the collections of heat source points in a travel direction along a weld line of a target, and to cause the collections of heat source points to combine based on a position along the weld line, each of the linear profiles forms an oblique angle relative to the travel direction.
