Positive Material Identification  (PMI)

Accurate identification and control of material is vital at every stage of manufacture and operation. Analysis is effected by the use of portable spectrographic analysers capable of providing detailed composition data on a wide range of metals.

Positive Material Identification (PMI) is a process used to determine the elemental composition of components/materials being used in the fabrication of critical applications in a wide range of industries such as finished welds, clad surface & overlays, Electronic components and Oil & Gas components and weldments. The test identifies the alloys that make up a particular material. The purpose of alloy verification is to ensure that only materials that are specified as part of the design requirements are supplied and used.

Main benefits of PMI:

• Immediate result of alloy in question
  
• No need to destroy part by having to cut sample out for analysis
  
• Minimum surface preparation
  
• Portable analysis machine
  
• Verification of material certificates
  
• In-service inspection
  
• Fast implementation of an analysis
