Method for manually laser welding metallic parts
First Claim

1. A method for welding a metal part with a laser that generates a laser beam, the method comprising:
- manually feeding successive portions of a filler material with a hand of a user to a process location that is adjacent the metal part and is in a pathway of the laser beam;
generating the laser beam, wherein the laser beam melts the manually fed successive portions of the filler material;
cooling the melted successive portions of the filler material, thereby allowing the melted successive portions to fuse to the metal part; and
controlling an intensity of the laser beam based on a sensed position of the user'"'"'s hand relative to the laser beam.

Abstract
A method for welding a metal part with a laser that generates a laser beam, where the method includes manually feeding successive portions of a filler material adjacent the metal part and in a pathway of the laser beam, generating the laser beam for melting the filler material, and cooling the melted filler material for fusing the filler material to the metal part. The method further includes controlling an intensity of the laser beam based on a sensed position of a user'"'"'s hand relative to the laser beam.

10. A method for welding a metal part with a laser that generates a laser beam, the method comprising:
-
switching an actuator between an inactive state and an activated state;
manually feeding successive portions of a filler material with a hand of a user to a process location that is adjacent the metal part and is in a pathway of the laser beam;
sensing a position of the user'"'"'s hand with a sensor, wherein the sensor switches from a first state to a second state based on the sensed position of the user'"'"'s hand relative to the laser beam;
controlling the laser to generate the laser beam at an operating level when the actuator is in the activated state and the sensor is in the first state, wherein the laser beam melts the manually fed successive portions of the filler material. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method for restoring a surface of a metal part with a laser that generates a laser beam, the method comprising:
-
positioning the surface of the metal part in a pathway of the laser beam;
retaining a filler material with a hand of a user;
manually positioning the filler material adjacent the surface of the metal part and in the pathway of the laser beam;
sensing a position of the user'"'"'s hand with a sensor, wherein the sensor switches from a first state to a second state when the user'"'"'s hand enters a nominal hazard zone of the laser beam;
controlling the laser to generate the laser beam at an operating level when the sensor is in the first state, wherein the laser beam melts the filler material, thereby allowing the melted filler material to fuse to the surface of the metal part. - View Dependent Claims (17, 18, 19, 20)
