📋 Overview	Machinists set up and operate computer-controlled (CNC) and manual machine tools to produce precision metal parts.	Welders join and cut metal parts using intense heat and pressure to construct bridges, pipelines, ships, and structures.
⚡ Tasks AI May Automate	✕ Generating 5-axis CNC G-code toolpaths from CAD models ✕ Automated tool wear compensation and breakage sensor monitoring ✕ Robotic part loading and pallet switching on production runs ✕ Coordinate Measuring Machine (CMM) automated inspection reports	✕ Robotic repetitive sheet metal spot welding on conveyor lines ✕ Automated ultrasonic weld seam defect scanning ✕ Laser cutting machine toolpath optimization ✕ Weld wire and shielding gas flow rate calibration
🛡️ Human Strengths	✓ Designing custom rigid workholding fixtures for delicate parts ✓ Listening to machine chatter to adjust feed rates and prevent tool breakage ✓ Hand-scraping and lapping precision tool and die surfaces ✓ Selecting optimal cutting feeds for temperamental aerospace superalloys	✓ TIG welding exotic alloys (titanium, Inconel) with steady hand finesse ✓ Climbing scaffolding to weld structural steel in freezing crosswinds ✓ Executing high-stakes pressure vessel pipeline root passes ✓ Custom architectural blacksmithing and metal art fabrication
