Powder weld fishing tool

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

• a fishing tool comprising:
• a main body assembly;
• one or more nozzles configured to dispose a cladding powder on the object when the object is proximate to the tool;
• and
• one or more lenses configured to direct a laser beam at the cladding powder disposed on the object, thereby welding the fishing tool to the object such that pulling the tool in an uphole direction pulls the object along with the fishing tool;
• and,
• a conveyance connected to the fishing tool, wherein the system is configured such that, after welding the fishing tool to the object, raising the fishing tool uphole, by the conveyance, pulls the object uphole 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 assembly;
• one or more nozzles configured to dispose a cladding powder on the object when the object is proximate to the tool;
• and
• one or more lenses configured to direct a laser beam at the cladding powder disposed on the object;
• spraying, when the tool is proximate the object, the cladding powder on the object from the one or more nozzles;
• transmitting laser light through the optical fiber to the one or more lenses, such that the lens directs a laser beam on the cladding powder, thereby welding the fishing tool to the object;
• and
• after welding the fishing tool to the object, raising the fishing tool uphole by the conveyance assembly, thereby pulling the object along with the fishing tool.
