Laser cladding fishing tool

A downhole fishing system for retrieving an object from a wellbore, the system comprising:

• a fishing tool comprising:
• a main body comprising a tubular assembly configured to be positioned in the wellbore;
• and
• a lens configured to direct a laser beam circumferentially along a first ring of cladding wire when the first ring is in contact with the object, thereby welding the first ring to the object, and subsequently to direct the laser beam circumferentially along a second ring of cladding wire disposed above the first ring, thereby welding the second ring and the first ring together with the tubular assembly;
• and
• a conveyance configured to lower the fishing tool downhole and raise the tool uphole in the wellbore and configured such that, with the first ring and the second ring are so welded, subsequently raising the fishing tool uphole, by the conveyance, pulls the object along with the tool.

A method for retrieving an object from a wellbore, the method comprising:

• lowering, by a conveyance assembly comprising an optical fiber, a fishing tool downhole within a wellbore, the fishing tool comprising:
• a main body comprising a tubular assembly;
• and
• a lens configured to direct a laser beam circumferentially about a downhole end of the tubular assembly;
• contacting a first ring of cladding wire with the object;
• directing, through the lens, a laser beam along the first ring, thereby welding the first ring to the object;
• disposing a second ring of cladding wire above the first ring;
• direct the laser beam circumferentially along the second ring of cladding wire, thereby welding the second ring and the first ring together with the tubular assembly;
• and
• with the first ring and the second ring so welded, raising the fishing tool uphole by the conveyance assembly, thereby pulling the object along with the fishing tool.
