NCCER Boilermaker study plan

Match 15 common boilermaking hazards (hot work, confined space, elevated work, pinch points, stored energy, chemical exposure) to the specific PPE and control measure for each.

Sequence lockout/tagout and confined space entry steps for a vessel-entry scenario, including atmospheric testing order and permit sign-off points.

Identify the correct hand and power tool for six fabrication tasks and state the pre-use inspection finding that would cause you to reject each tool.

Select the correct fire extinguisher class and describe fire-watch duties and duration for cutting and welding operations.

Assemble an oxyfuel cutting outfit in the correct order (cylinders, regulators, flashback arrestors, hoses, torch) and list the leak-test step for every joint.

Distinguish neutral, oxidizing, and carburizing flames by appearance and state the correct flame for steel cutting, preheat, and brazing.

Describe how cutting oxygen pressure, tip size, and travel speed change kerf quality and dross formation.

Match common SMAW electrodes (E6010, E6011, E7018) to base metal, position, and current type, and name the defects caused by wrong amperage, arc length, and travel speed.

Diagnose ten weld defects from written descriptions (porosity, slag inclusion, undercut, lack of fusion, cracking) and name the process variable most likely to cause each.

Extract scale, material, quantity, and revision data from the title block, revision block, and bill of materials of a sample fabrication drawing.

Identify line types, view placement, and dimensioning conventions used in third-angle orthographic drawings.

Decode ten welding symbols, reading size, length, pitch, and tail instructions from the reference line.

Project a third view from two given orthographic views and check each projected line for correct alignment.

Develop flat patterns for a cylinder and a truncated cylinder using parallel line development.

Calculate bend allowance and cut length for formed plate parts from given inside radii and thicknesses.

Compute plate area, weight from material density, and total weld length for a small assembly take-off.

Identify wire rope, chain, and synthetic web slings and state the inspection findings that require removal from service.

Calculate tension per leg for two-leg and four-leg bridle hitches at 30, 45, and 60 degree horizontal angles.

Determine load weight, center of gravity, and the appropriate hitch type for a given vessel or structural component.

State standard crane hand signals and the correct placement of tag lines, softeners, and spreader beams.

Select and describe safe use of chain falls, come-alongs, jacks, and roller skids for moving a horizontal vessel, listing the hold points for each device.

Distinguish firetube from watertube boiler construction and label the main pressure parts of each.

Identify pressure vessel components and interpret nameplate data, MAWP, and code stamp markings.

Label the internals of a shell-and-tube heat exchanger (tubes, tubesheet, baffles, shell, channel, pass partition) and trace the flow path through a two-pass unit.

Describe tube rolling and expansion, gasket selection, and the bolt torque sequence for a flanged joint.

Outline a hydrostatic test procedure, including test pressure relative to MAWP, venting, and inspection hold points.

List boiler inspection points for tubes, tubesheets, staybolts, and refractory, and name the defect each inspection targets.

Explain the causes and remedies for common boiler and exchanger failures: tube rupture, caustic embrittlement, erosion-corrosion, and gasket leakage.

Re-drill the two weakest topics identified in the week 4 and week 6 milestone checks until practice accuracy exceeds 85%.

Complete a timed full-length practice exam under exam conditions without notes or reference material.
