BOILERMAKERS make, assemble, and
repair different kinds of boilers, steel pressure vessels, vats, and tanks
according to blueprints. Their work involves aligning sections of plates
to assemble boiler frames, tanks and vats, cutting tubes from metal, drilling
holes, and bolting, riveting, or arc welding the sections or structures
They are also responsible for preparing
sheet metal for welding, stress relieving, and heat duration, and for testing
the finished vessels by pumping water or gas through them under specified
pressures and observing instruments to detect leakage.
BOILERMAKERS use blueprints, hand
tools and power equipment, such as plumb bobs, wedges, levels, dogs, turnbuckles,
caulking hammers, arc welders, rivet guns, bending machines, drill presses.
They make gear guards, floats, and pans from metal sheet. They set up rigging
and erect portable swinging scaffolds using proper slings, chains, hoists,
and rope blocks to make smokestack repairs.
BOILERMAKERS may work indoors or
outdoors, often under conditions of dampness, heat, poor ventilation, and
cramped quarters, and on swinging scaffolds at considerable heights. The
work involves heavy lifting and manipulating bulky parts into position
manually, much standing and climbing, and strenuous reaching, stretching,
bending, and pushing and pulling. Hazards of the job include exposure to
fumes, burns, cuts and falls.
