Detection of corner defects
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.
