Non-Destructive Testing (NDT) Services
Los Angeles & Orange County, California
Non-Destructive Testing (NDT), also known as Non-Destructive Evaluation (NDE), is a critical inspection service for structural steel projects throughout Southern California, particularly in high seismic zones such as Los Angeles and Orange County. NDT allows for the evaluation of weld integrity and material performance without damaging the structure, ensuring safety, compliance, and long-term durability.
Reliant Testing Engineers, Inc. provides certified NDT inspection services for commercial, industrial, and infrastructure projects. Our experienced technicians specialize in identifying weld discontinuities and structural deficiencies in accordance with California Building Code (CBC) requirements and applicable industry standards.
Certified NDT Inspection Services in Southern California
Our NDT services—especially Ultrasonic Testing (UT)—require advanced knowledge of structural steel connection types and welding configurations that can significantly affect test interpretation. Reliant Testing’s inspectors are thoroughly trained to recognize these complexities and are supported by in-house engineering expertise to ensure accurate, defensible inspection results.
Our NDT program follows the strictest quality and certification standards, including:
- ASNT SNT-TC-1A recommended practices
- AWS D1.1 Structural Welding Code
- ASME standards
- Post-Seismic Evaluation Survey procedures
These standards ensure consistent, reliable inspections for projects throughout Los Angeles County, Orange County, and greater Southern California.
Ultrasonic Testing (UT) Services
Ultrasonic Testing (UT) is used to detect internal weld defects in both Complete Joint Penetration (CJP) and Partial Joint Penetration (PJP) welds. UT is commonly required for:
- Seismic moment-resisting frames
- Structural steel connections
- Process piping and industrial systems
This method provides precise, subsurface evaluation and is widely accepted for seismic compliance in California construction projects.
Magnetic Particle Testing (MT) Services
Magnetic Particle Testing (MT) is an effective method for inspecting fillet welds and other ferromagnetic materials. Often used alongside visual inspection, MT can detect surface and near-surface discontinuities up to 1/8 inch below the surface, making it a valuable tool for quality control and weld verification.
Dye Penetrant Testing (PT) Services
Dye Penetrant Testing (PT) identifies surface-breaking weld defects using a penetrating liquid dye followed by a developer to enhance visibility. This method is ideal for detecting cracks, porosity, and other surface imperfections in welds and fabricated steel components.
