TechCorr Non-destructive Testing Positive Material Identification

Niton™ XL2 XRF Analyzer—one of the scanners used by TechCorr for PMI

Fast and Reliable

TechCorr’s positive material identification (PMI) provides alloy chemistry and grade ID information in seconds using a hand-held scanner.

PMI is also commonly used to ensure:

  • the composition of the parent material is correct
  • the correct filler material was used during equipment repair.

On-the-Spot Results

With PMI there is:

  • no transporting material
  • no altering material
  • no damaging material.

Using hand-held scanners means we can:

  • minimize costs associated with extensive lab analyses, especially when high volumes of testing are required
  • conduct on-location testing for materials that are difficult to transport to the lab
  • facilitate material testing at the manufacturing point
  • assign a quality and production pass/fail status immediately or make required adjustments
  • trouble-shoot potential problems before failures occur.

Versatile and Comprehensive

Our scanners can be used to inspect virtually any equipment, including :

  • finished welds and weld beads
  • bolts, rivets, and other fasteners
  • valves and flanges
  • complete reaction vessels.

They are engineered for in-service inspection of systems with temperatures in excess of 800°F (426°C).

A Variety of Scanners

TechCorr has a variety of scanners available for use, including:

  • Niton™ XL2 XRF Analyzer—for standard optical PMI
  • Oxford Instruments™ PMI Master Arc Probe—ideal determining a material’s carbon content.

Broad Applications

TechCorr uses scanners with an extensive library of alloy grades. Families of alloys that can be accurately identified and analyzed include:

  • stainless steels
  • Cr-Mo steels including, vanadium and tungsten stabilized versions
  • low alloy steel
  • tool steels
  • nickel, copper, titanium, and aluminum alloys
  • exotics, such as zirconium and tantalum alloys.
