About BILLETCHEK

Detection of corner defects

  • For detection of transverse cracks or short longitudinal defects
  • Inspects square billlets, 80-130 mm on one side (3-5 inches)
  • System allows for billet deformation such as warp and twist
  • Includes marking unit for marking of defects on all four corners
BILLETCHEK was designed especially for detecting cracks in the corners of billets with a square profile. The billet is guided on rollers between four special corner probes. To allow for billet deformations such as warping and twisting, the probes are pneumatically suspended in a spring loaded frame that moves with the billet. After inspection, the billet passes through a 4-point marker that marks defects identified by the EDDYCHEK eddy current inspection system. Test results were fully documented.
