Testing & Inspection Services

Welding Inspection By AWS Certified Inspectors

Quality is the highest priority for us. This is demonstrated by having American Welding Society (AWS) Certified Weld Inspectors (CWI) on staff. The benefits of doing so include the following: the ability to conduct in‐process inspections both during welding cycles and at critical control points; and the opportunity to document findings throughout the process.

We can provide documentation at any point during the process to validate that the product is being manufactured to the drawings and specifications provided.

Proactive Non-Destructive Testing

We operate well‐managed programs that ensures top‐quality results. The following are Non-Destructive tests performed onsite or in‐house:

Magnetic Particle (MT)

By running a magnetic current to find flaws and cracks on the surface and near-surface of ferromagnetic materials

Liquid Penetrant (PT)

Produces flaw indications with liquid colored or fluorescent dyes

Ultrasonic Test (UT)

Using special equipment to create high frequency sound waves to penetrate material thickness

Visual Test (VT)

Trained visual inspectors use their knowledge, designs and product documents for inspections using their vision

Other testing

Functional, Hydro, and Proof Testing

Quality Systems

Our facility, welding engineers and certified welders have the highest certifications.

Standard for Non-Pressure Vessel Applications

Our Standard quality program is qualified to MIL‐I‐45208 and is ISO 9001:2015 certified.
