(Commonly referred to as NDT, NDE, or CWI)
Nondestructive testing is a method used to evaluate components, subassemblies, or process systems that preserves the original state of the article under test. Nondestructive testing can be utilized in the research and development phase of product design or any time a test is required that prevents damage to the unit or system while undergoing testing.
Commonly used methods of nondestructive testing include Eddy-Current (ET), Liquid Penetrant (PT), Leak Testing (LT), Magnetic Particle (MT), Radiographic (RT), Ultrasonic (UT), and Visual (VT) methods. At LTS, in addition to VT and PT, we specialize in multiple leak testing methods. These include Bubble Testing (BT), Helium Mass Spectrometer Leak Testing (MSLT), Pressure Change Measurement Leak Testing (PCMT), Thermal Conductivity Leak Testing, Acoustic Leak Testing, and Visual Leak Testing.
Nondestructive leak testing is utilized in a multitude of industrial applications including the following:
LTS staff is qualified/certified as Level I, Level II, or Level III in compliance with ASNT/SNT-TC-1A and ANSI/ASNT CP-189. All training and qualifications are performed by our own ASNT-certified, leak test Level III examiners.
LTS also employs inspectors certified as American Welding Society (AWS) Certified Welding Inspectors (CWI).
To achieve all certification levels, both written exams and practical testing must be successfully completed.
The AWS Certified Welding Inspector (CWI) certification is obtained through the American Welding Society. All work by LTS AWS CWI personnel is performed in strict compliance with the LTS NQA-1-compliant Quality Assurance Program.
