Xstress Robot

Xstress Robot is an advanced X-ray stress analyzer based on solid state linear sensor technique. It is capable of making measurements by X-ray diffraction easy and flexible with complicated parts, large or small.

• Non-destructive
• Accurate 6-axis industrial robot (additional axis possible as an option)
• Automatic mapping on complicated parts, such as turbine blade is possible
• Movable or fixed installation with safety enclosure
• Easy replacement of X-ray tube (Cr, Cu, Co, Fe, V, Ti, Mn) which enables measuring different materials
• Three measurement distances as standard: 50, 75 and 100 mm
• Two NMOS position sensitive detectors
  Instantly adjustable 2θ-angle
• XTronic software for running the measurement and calculating residual stresses and retained austenite content (optional)
• d-sin²χ and Ω-measurement modes as a standard

Features

• standard detector width 30°
• for other detectors see options

2θ-range of the detectors

• continuously adjustable within 110° to 165°
• lower angles as option with special detector arcs

Standard measurement distance 50 mm

Replaceable collimators

• short and long collimators with 1/2/3/4/5 mm spot sizes

XTronic software

• fully featured Windows software using thread based multi-tasking
• hardware operation control: detectors, DC motors, power supply, shutter, safety interlock functions, voltage and current, etc.
• automated calibration with zero stress powder samples to set diffractometer to sample distance
• project manager for depth distribution measurement and all kinds of mapping measurements
• library functions for material parameters
• modified d-sin2χ and Ω-mode
• peak shift determination with the most known methods such as cross-correlation and peak fit methods
• peak fit with eight different functions and three background options: Gauss, Lorentz, Modified Lorentz, Intermediate Lorentz, Pearson VII, Split Pearson VII, Pseudo-Voigt and Split Pseudo-Voigt

Safety

ANSI N43.3 – 1993

• Meets or exceeds ANSI N43.3 – 1993 and other industry standards for open beam X-ray operation.
• X-ray diffractometer safety regulations in general
