Portable Residual Stress Analyzer

Non-destructive analysis on any dimensions sample for indoor and outdoor analysis. 

* EN UNI 15305 and ASTM 915 compliant 

* Indoor and Outdoor Analysis 




SpiderX is the new GNR portable residual stress analyzer. It has been designed focusing on exceptional portability lightness, easiness to set up, outstanding performances and negligible X-Ray emissions. 

The result is a compact and smart instrument, based on a low power X-Ray Tube and on a fast and highly efficient detector, the combination of which ensures accurate and fast measurements. 

The head of the goniometer rotates along a curved sector of 90 degrees, for the determination of the stress status in polycristalline materials. The 2Theta angle can be changed from 135° to 165° in order to analyze Fe (ferrite, austenite), Al, Ni, Cu, Ti and Mg Alloys. 

Compact Case and Portability

Portability is assured by a compact case. 

Supplied together with the instrument, provides a safe housing of the goniometer, electronical part and all the accessories required. It is exactly like a trolley!

Outdoor Analysis

  • Non Destructive on-site measurement of big sample 
  • Easily access to the measurement point thanks to the versatility of the goniometer head 
  • Battery allows on-site measurement without the main power supply 
  • Single case contains goniometer and power supply with a total weight of approx. 19 kg. 

Indoor Analysis

  • SpiderX can be used also for indoor analysis into a laboratory 
  • Anthropomorphic arm allows changing easily the measuring point 

Some specific applications of the Stress-X are listed below: 

  • Detection of Residual Stress on sprocket wheels 
  • Detection of Residual Stress on car motor parts (cam axles, connecting rods, engine shafts, equalisers, ...) 
  • Detection of Residual Stress induced by deep drawing (household appliances, structural parts, ...) 
  • Detection of existing Operational Stress on gas conducts 
  • Detection of Operational Stress on large tensioned structures 
  • Measurement of efficiency of Shot-Peening and rolling of components subjected to Stress 
  • Definition of the quantity of Retained Austenite on bearings and parts of diesel motor injectors 
  • Detection of Residual Stress in castings (cast iron parts of tool machines and aluminium components) 
  • Detection of Stress induced by welding (laser and electron) 
  • Search for a correlation between residual stress and stress resistance of aluminium alloy car rims
  • Optimisation of working parameters for swarf removal to improve the stress resistance of mechanical components 
  • Detection of Residual Stress on helicoidal and leaf springs 
  • Search for critical zones after applying work loads (arms and aeronautics)
