Abstract
Systems and methods of a laser welding device to weld aluminum are disclosed. The device includes a laser generator to generate welding-type lasing power and a lens to focus the welding-type lasing power at a focal point on an aluminum workpiece to generate a weld puddle. A laser scanner to control the lens to move the focal point of the welding-type lasing power in multiple dimensions over the aluminum workpiece during welding, the laser generator and the laser scanner to perform the welding without filler metal being added to the workpiece.

A laser welding device to weld aluminum, comprising:
- a laser generator to generate welding-type lasing power;
- a lens to focus the welding-type lasing power at a focal point on an aluminum workpiece to generate a weld puddle;
- and
- a laser scanner to control the lens to move the focal point of the welding-type lasing power in multiple dimensions over the aluminum workpiece during welding, the laser generator and the laser scanner to perform the welding without filler metal being added to the workpiece.
A method to weld aluminum, comprising:
- generating welding-type lasing power;
- focusing the welding-type lasing power at a focal point on an aluminum workpiece using a lens to generate a weld puddle;
- and
- controlling the lens with a laser scanner to move the focal point of the welding-type lasing power in multiple dimensions over the aluminum workpiece to perform the welding without filler metal being added to the workpiece during welding.
