Our Services
Timely reports are #1
- Upon completion of your metals testing or analysis, a comprehensive report will be provided with a summary of test data, referenced test specification, and instrumentation data.
PWHT : Post (after) Weld Heat Treat
- Post weld heat treatment (PWHT) refers to any heat treatment performed after machining/welding to improve the mechanical and chemical properties of the machined surfaces/weldment. Welding induces residual stresses in a structure, which cause distortions in the structure in the long term.
Charpy Impact Testing
- Impact resistance testing, such as Charpy and Izod impact tests, measures the amount of energy absorbed by a material during fracture. During a impact resistance test, a specimen with a notched ‘pre-crack’ is subjected to a sudden impact load. By measuring the energy absorbed as the crack lengthens, the material’s toughness and resistance to crack extension is determined. Testing is often performed at various temperatures to determine the ductile to brittle transformation temperature.
Macro-Etch
- Macro etch test is a technique used to test a weld by revealing the structure of the base material and weld. It's a destructive testing method that is used to evaluate the characteristics of the weld.
Micro hardness
- Micro hardness testing of metals, composites and minerals is employed where a superficial hardness test is not possible due to a small sample geometry or area of interest. Micro hardness tests can be used to provide necessary data when measuring individual microstructures within a larger matrix, thin materials, coatings, or when determining the hardness gradient of a specimen along a cross section, such as a weld heat affected zone.
