NCCER Welding study guide
NCCER Welding · Work through your exam, one topic at a time.
NCCER is a 501(c)(3) nonprofit education foundation created in 1996 that describes itself as the nation's leader in providing construction industry education, assessments, credentials and accreditation. Its welding credential sits inside a craft catalog of training programs that NCCER says are built for industry by industry, and its credentials span all construction trades - serving both emerging and experienced craft professionals. The NCCER Welding study guide has 5 sections and about 1,874 words.
01Welding Safety and Health
This domain tests the safety decisions a welder makes before, during, and after hot work: PPE selection, fume and ventilation control, electrical protection, compressed-gas handling, and fire prevention. NCCER-style items often ask for the specific control, not a general warning.
429 words, about 2 min02Oxyfuel Cutting and Heating
This domain tests setup and manipulation of the oxyfuel torch: flame adjustment, tip selection, cutting technique, kerf and drag, and the safety devices that separate a normal backfire from an emergency flashback. An oxyacetylene torch uses a neutral flame-equal oxygen and acetylene-for steel cutting and most heating.
383 words, about 2 min03Base Metal Preparation and Weld Quality
This domain covers fit-up and cleaning before the arc, plus the defects and inspection methods used to judge a finished weld. Exam items tend to link a preparation error to a specific discontinuity.
380 words, about 2 min04Shielded Metal Arc Welding (SMAW)
This domain tests electrode classification, current and polarity selection, arc control, low-hydrogen storage, and the relationship between welding variables and weld soundness. Read E7018 from left to right: E is electrode; 70 is minimum tensile strength in ksi (70,000 psi); 1 means all positions; 8 is a low-hydrogen iron-powder coating that runs on AC or DCEP.
315 words, about 2 min05Wire Feed and Tungsten Arc Processes (GMAW, FCAW, GTAW)
This domain tests the setup logic of the wire-feed and tungsten-arc processes: transfer mode, shielding gas, polarity, wire-feed variables, tungsten preparation, and the defects that follow from a wrong setting. GMAW uses a continuous bare wire, a constant-voltage power supply, and DCEP.
