Boilermakers

Study blueprints to determine locations, relationships, or dimensions of parts.

AI: Fully automatable - AI can read CAD/blueprints, extract dimensions and spatial relationships reliably and generate placement instructions or models with high accuracy.

Lay out plate, sheet steel, or other heavy metal and locate and mark bending and cutting lines, using protractors, compasses, and drawing instruments or templates.

AI: Fully automatable - Digital CAD nesting, CNC/robotic scribing and automated layout tools can fully produce and mark bending/cutting lines that humans would otherwise measure with protractors and templates.

Examine boilers, pressure vessels, tanks, or vats to locate defects, such as leaks, weak spots, or defective sections, so that they can be repaired.

AI: Fully automatable - AI-driven NDT (radiography, ultrasound, thermal, acoustic) and image-analysis systems can autonomously detect leaks, weak spots, and defective sections in many inspection contexts as of 2025.

Inspect assembled vessels or individual components, such as tubes, fittings, valves, controls, or auxiliary mechanisms, to locate any defects.

AI: Fully automatable - Sensor- and camera-based inspection systems combined with AI can locate many defects in assembled components (tubes, fittings, valves) without direct human inspection in common use cases.

Attach rigging and signal crane or hoist operators to lift heavy frame and plate sections or other parts into place.

AI: Partial - AI can support rigging planning, sensor-assisted alignment, and semi-autonomous cranes, but safe, context-sensitive attachment and signaling in variable sites remain largely human-driven in 2025.

Repair or replace defective pressure vessel parts, such as safety valves or regulators, using torches, jacks, caulking hammers, power saws, threading dies, welding equipment, or metalworking machinery.

AI: Partial - Automated welding and diagnostics can handle some repair tasks, but complex, irregular pressure-vessel repairs requiring on-site judgment and manual tooling are not fully automatable yet.

Locate and mark reference points for columns or plates on boiler foundations, following blueprints and using straightedges, squares, transits, or measuring instruments.

AI: Partial - Survey-grade lasers, computer vision and robotic layout systems can compute and mark reference points, but final verification and adaptation to site irregularities commonly need humans.

Bolt or arc weld pressure vessel structures and parts together, using wrenches or welding equipment.

AI: Partial - Robotic welding and bolting systems excel in controlled production settings, but variable field conditions and bespoke pressure-vessel joins still require skilled human operators for many jobs.

Position, align, and secure structural parts or related assemblies to boiler frames, tanks, or vats of pressure vessels, following blueprints.

AI: Partial - AI can plan alignment and use assisted positioning tools or jigs, yet precise on-site positioning and securing of large assemblies under changing conditions remain partly manual.

Install manholes, handholes, taps, tubes, valves, gauges, or feedwater connections in drums of water tube boilers, using hand tools.

AI: Partial - AI can guide and partially automate preparation and placement, but the fine manual installation and sealing of fittings in boilers are still predominantly performed by humans.

Bell, bead with power hammers, or weld pressure vessel tube ends to ensure leakproof joints.

AI: Partial - Welding and tube-end beading/belling are automatable in controlled shop environments, but field tube-end work and power-hammer operations for pressure vessels remain only partially automated.

Shape or fabricate parts, such as stacks, uptakes, or chutes, to adapt pressure vessels, heat exchangers, or piping to premises, using heavy-metalworking machines such as brakes, rolls, or drill presses.

AI: Partial - CNC and AI-driven metalworking can fully fabricate many parts in shops, but adapting complex shapes to specific premises and ad-hoc modifications generally require human skill in 2025.

Assemble large vessels in an on-site fabrication shop prior to installation to ensure proper fit.

AI: Partial - Robotic assembly and AI-guided tooling can assist and automate repetitive, controlled shop assembly steps, but on-site, bespoke fitting and adaptive adjustments still require skilled human workers.

Shape seams, joints, or irregular edges of pressure vessel sections or structural parts to attain specified fit of parts, using cutting torches, hammers, files, or metalworking machines.

AI: Partial - Shaping seams and irregular edges with torches, hammers and ad-hoc metalworking still requires skilled manual manipulation and judgment, though partial robotic/automated machining assistance exists.

Straighten or reshape bent pressure vessel plates or structure parts, using hammers, jacks, or torches.

AI: Partial - Straightening and reshaping bent plates require complex force control, localized heating and adaptive techniques that remain largely manual despite some robotic aids.

Install refractory bricks or other heat-resistant materials in fireboxes of pressure vessels.

AI: Partial - Installing refractory bricks in confined fireboxes requires fine placement, material handling and adaptation to irregular conditions, so only partial robotic assistance is available.

Clean pressure vessel equipment, using scrapers, wire brushes, and cleaning solvents.

AI: Partial - Cleaning pressure-vessel interiors can be automated in some repeatable settings, but variable geometries, residues, and access constraints mean human work is still commonly required.
