NDT Magnetic Particle Testing Services

Magnetic particle testing is a type of non-destructive testing weld inspection that generates magnetic flux to discover surface or near surface abnormalities, flaws or damage in items composed of steel or iron.

A portable electric generator is used to generate a current that results in magnetic flux for welding inspection, which is then measured by how it separates ferrous materials like iron filings found in the object in question. Our CWI will read this flux to detect the presence of any cracks, gaps, or other issues and note them accordingly.

The advantages of Magnetic Particle Testing include:

    • Inexpensive compared to other methods, saving you money

    • Is fast and accurate

    • Can detect surface and below surface discontinuity

    • Is portable and requires minimal preparation

    • Can detect gaps that other types of testing could miss

Liquid Penetrant Testing Services

Geo-Per International also provides liquid penetrant weld testing services to simply and accurately detect surface breaks.

This NDT (non-destructive testing) method employs the use of a dye that is applied to a fully cleaned object. After this dye has been applied by a CWI and left to sit for about fifteen minutes, a chalk is applied to the welding inspection item in question, revealing any surface breaks or gaps that may otherwise be difficult to see.

Some of the benefits to Liquid Penetrant Testing include:

    • Highly portable

    • Typically conducted within 30 minutes

    • Capable of detecting very small gaps or other discontinuities

    • Extremely cost effective

    • Highly accurate weld testing for detecting surface abnormalities

Visual Testing Service

Visual weld testing is exactly what it sounds like; an experienced CWI conducts a visual welding inspection, searching for abnormalities, flaws or breaks. As the first and most obvious type of NDT, visual testing (VT) can be conducted relatively quickly (depending on the size of the weld(s)) and brings to bear the vast experience of our CWI in a hands on approach.

Ultrasonic Testing Service

Ultrasonic Testing conducted by a CWI is a highly efficient method of NDT (non- destructive testing) that is very accurate.

Ultrasonic equipment is used to conduct an ultrasonic pulse into the weld area, which can reveal surface and sub-surface breaks or flaws. This NDT type when conducted by one of our highly skilled CWI staff can reveal very small discontinuities and flaws in a variety of materials.
