* Construct, assemble, maintain, and repair stationary steam boilers and boiler house auxiliaries. Align structures or plate sections to assemble boiler frame tanks or vats, following blueprints. Work involves use of hand and power tools, plumb bobs, levels, wedges, dogs, or turnbuckles. Assist in testing assembled vessels. Direct cleaning of boilers and boiler furnaces. Inspect and repair boiler fittings, such as safety valves, regulators, automatic-control mechanisms, water columns, and auxiliary machines.

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

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

* 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.

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

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

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

* 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.

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

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

* 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.

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

* 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.

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

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

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

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

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