How much do magnetic particle inspection jobs pay per hour?

As of Aug 17, 2026, the average hourly pay for magnetic particle inspection in California is $19.57, according to ZipRecruiter salary data. Most workers in this role earn between $15.19 and $22.31 per hour, depending on experience, location, and employer.

What is magnetic particle inspection?

Magnetic Particle Inspection (MPI) is a non-destructive testing method used to detect surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, and cobalt. The process involves magnetizing the material and then applying ferrous particles over the surface. If there are any cracks or defects, the magnetic field is disrupted, causing the particles to gather at the site of the flaw, making it visible under proper lighting conditions. MPI is widely used in industries like aerospace, automotive, and manufacturing for quality control and safety assurance.

What skills and qualifications are needed to thrive as a magnetic particle inspection technician?

To thrive as a Magnetic Particle Inspection (MPI) Technician, you need a solid understanding of non-destructive testing principles, attention to detail, and typically a certification such as ASNT Level I or II. Familiarity with MPI equipment, UV lights, yokes, and documentation systems is crucial for accurate inspections. Strong observational skills, problem-solving ability, and effective communication help technicians identify defects and report findings clearly. These skills and qualifications are important to ensure the safety, integrity, and compliance of materials and components in industries like aerospace, automotive, and construction.

What are the most common challenges faced by magnetic particle inspection technicians on the job?

MPI technicians often encounter challenges such as interpreting ambiguous indications, working in confined or awkward spaces, and ensuring proper surface preparation to avoid false readings. Adhering to strict safety protocols when handling magnetic fields and chemicals is essential. Additionally, effective communication with other inspectors and engineers is crucial for accurately documenting and reporting findings, which directly impacts the integrity and safety of inspected components.

What is the difference between Magnetic Particle Inspection vs Ultrasonic Testing?

AspectMagnetic Particle InspectionUltrasonic Testing
CredentialsLevel I/II certifications in magnetic particle testingLevel I/II certifications in ultrasonic testing
Work EnvironmentMagnetic fields, surface and near-surface flaw detectionSound wave transmission, internal flaw detection
Industry UsageManufacturing, aerospace, oil & gasManufacturing, aerospace, oil & gas

Both Magnetic Particle Inspection and Ultrasonic Testing are non-destructive testing methods used to detect flaws in materials. Magnetic Particle Inspection is ideal for surface and near-surface flaws in ferromagnetic materials, while Ultrasonic Testing can detect internal flaws in a wider range of materials. The choice depends on the specific inspection needs and material type.

How much does a magnetic particle inspector make?

A magnetic particle inspector typically earns between $40,000 and $70,000 annually, depending on experience, certifications, and location. Skilled inspectors with certifications like ASNT Level II or III may earn higher wages, especially in industrial or aerospace settings.

Is magnetic particle inspection a good career?

Magnetic particle inspection is a specialized nondestructive testing method used to detect surface and near-surface flaws in ferromagnetic materials. It offers steady employment opportunities in industries such as manufacturing, aerospace, and power generation, often requiring certification and knowledge of magnetic fields and inspection tools. The career can be stable and rewarding for those with technical skills and attention to detail.

Job description

Pay range-$30-$50/hr DOE
Core Responsibilities
  • Testing Operations: Perform NDT methods-such as Ultrasonic (UT), Magnetic Particle (MT), Dye Penetrant (PT), or Radiographic (RT) testing-to detect internal and external weld flaws (e.g., cracks, porosity, or lack of fusion).
  • Equipment Management: Calibrate, maintain, and troubleshoot specialized inspection and testing equipment to ensure accuracy and reliability.
  • Code Compliance: Review blueprints, welding symbols, and Welding Procedure Specifications (WPS) to verify that welding operations align with codes set by the American Welding Society or other regulatory bodies.
  • Reporting: Document findings, generate formal inspection reports, and identify non-conforming work requiring repair or remediation.
  • Field & Lab Work: Collaborate with project managers, structural engineers, and welders across construction sites, manufacturing plants, shipyards, or refineries.

Key Qualifications
  • Welding Proficiency: Background in structural welding processes like GMAW, GTAW, SMAW, or FCAW.
  • NDT Certifications: ASNT (American Society for Nondestructive Testing) Level II or III certifications in specific testing disciplines (VT, MT, PT, UT, RT).
  • Inspection Credentials: Often requires or highly values an AWS Certified Welding Inspector (CWI) credential.
  • Blueprint Reading: Strong ability to interpret engineering drawings, welding symbols, and technical specifications.
  • Safety Knowledge:

Requirements
MANDATORY QUALIFICATIONS:
Fusion Welding for Aerospace Applications Specifications.
Experience working with 0.010-0.030 tolerances is a MUST
Basic understanding of welding symbols per AWS 2.4
