About Us

OCTI provides the best service in the weld testing industry. Our services include Radiography, Liquid Penetrant, Magnetic Particle, Eddy Current, and Welder/Procedure Qualification.

Orange Coast Testing Inc. was founded in 1991 by Paul R May Jr.  Paul gained valuable and knowledgeable experience working for the family owned NDT business before starting his own company.  With the time at his family business and the 22 years within his own company, Paul now has an extensive background in the Non-Destructive Industry as well as the Aerospace and Defense Contractor Industry.

Radiograhic Inspection

X-Ray of castings, electronics, welds, composite materials and a variety of other products is our greatest capability.


Penetrant Inspection

Visible Dye and Flourescent Penetrant Inspections are utilized. Welds, castings, inservice fatigue crack detection and (with pre-penetrant etch) machined parts are processed.

Magnetic Particle Inspection

Wet Fluorescent Magnetic Particle Inspection is performed usimg a 6,000 Amp (FWDC, 3 Phase) stationary unit that can test parts up to 12 ft in length.

Pressure Test

Air, Dry-Nitrogen, oil and water are mediums used for leak and proof pressure testing.



Eddy Current Inspection

Discontinuities are detected with custom made ET probes. EDM notched calibration standards per alloy/temper are used for known defect standards.

Hardness Testing

Hardness testing for low-alloyed steels, high-alloyed steels, and non-ferrous metals.


Positive Material ID

We can determine the exact chemistry of your material and, in most cases, tell you the specification and grade of the material.

Metallographic Cross-Section

A cross section sample is obtained and then etched to reveal the inner structure of the weld. 

Tensile Test

A sample is obtained from a weld plate and then machined into a tensile test specimen using a vertical mill. 

Bend Test

Bend tests for ductility provide a simple way to evaluate the quality of materials by their ability to resist cracking or other surface irregularities during one continuous bend

Charpy V-Notch Test

The Charpy V-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture.

Classroom Training

Training to fit your schedule. Our facility and equipment used for training. On-site training is also available.
