Core Competencies (likely covered in all levels):
* Safety: OSHA regulations, lockout/tagout procedures, personal protective equipment (PPE), hazard identification and control, confined space entry, fall protection. This is a HUGE component.
* Blueprint Reading: Interpreting welding symbols, dimensions, tolerances, and other specifications on blueprints.
* Mathematics: Basic math skills (fractions, decimals, geometry, trigonometry) are essential for calculations related to measurements, materials, and fabrication.
* Hand Tools and Power Tools: Knowledge of various hand and power tools used in boilermaking, their proper use, maintenance, and safety procedures.
* Measuring and Layout: Accurate measuring, marking, and layout techniques.
* Welding: Types of welding processes (SMAW, GMAW, GTAW, etc.), welding techniques, weld symbols, weld quality inspection. The level of detail on welding will depend on the specific NCCER level.
* Material Handling: Safe and efficient methods for handling heavy materials and equipment.
* Fabrication: Processes involved in fabricating boiler components, including cutting, forming, bending, and assembling.
Advanced Topics (depending on the NCCER level):
* Boiler Construction: Specific knowledge of boiler components, assembly procedures, and inspection methods.
* Boiler Repair and Maintenance: Techniques for repairing and maintaining boilers, including troubleshooting and preventative maintenance.
* Code Compliance: Understanding and adhering to relevant codes and standards (ASME, etc.).
* Non-destructive Testing (NDT): Methods for inspecting welds and other components for defects (e.g., visual inspection, magnetic particle testing, ultrasonic testing).
* Hydraulic and Pneumatic Systems: Understanding of the systems used in boiler operation.
The questions will be a mix of multiple-choice, true/false, and potentially some short-answer or problem-solving questions. The difficulty and depth of the questions will vary depending on the specific NCCER level you're taking (Level 1, Level 2, etc.).
To best prepare, you should review the official NCCER curriculum for the Boilermaker program at your specific level. This curriculum will provide the most accurate and comprehensive outline of the topics covered on the exam. You should also seek out practice tests and other study materials.
