ASNT ASNT NDT Certifications License: Complete Roadmap
Follow this path to organize your licensing and exam preparation
Phase 1: Magnetism FundamentalsYou are here
Master ferromagnetism, the B-H curve, residual versus continuous magnetization, and the difference between longitudinal and circular fields.
Phase 2: Techniques and Equipment
Drill yoke, prod, coil, central conductor, and head-shot techniques; learn amperage formulas and how AC/DC/HWDC/FWDC current types change penetration.
Phase 3: Particles and Process Control
Study dry versus wet, visible versus fluorescent particle systems, suspension concentration, settling tests, lighting requirements, and pie gauge/Ketos ring checks.
Phase 4: Evaluation and Discontinuities
Practice distinguishing relevant, non-relevant, and false indications; recognize fatigue cracks, hot tears, laps, seams, and inclusions and apply accept/reject logic.
Phase 5: Codes, Standards, and Mixed Review
Interpret ASME Section V Article 7, ASTM E1444, ASTM E709, AWS D1.1, and API 1104 acceptance criteria; finish with timed mixed sets.

Quality Exam Prep Shouldn't Cost Hundreds
I'm Ran Chen, an engineer with 20+ years of coding experience. I passed my Life Insurance license, EA exam, SIE, Series 6, 63, 65, and finally the CFP® exam.
Through all these exams, one thing became clear: exam prep is expensive. But with AI, we can change that. Quality preparation can now be free for everyone.
