Study on the Magnetic Flux Leakage (MFL) for Fillet Weld Chunfei Guo1a, Lijun Wang1b and Min Zhang1 1School of Material Science and Engineering, Tianjin University, Tianjin Key Laboratory of Advanced Joining Technology Engineering, Tianjin, 300072, China aguochunfei@gmail.com, bwanglijun@tju.edu.cn Keywords: Magnetic flux leakage, Fillet weld, Yoke-testing, ANSOFT Abstract: The magnetic flux leakage (MFL) technique is widely used as a Non-Destructive Testing (NDT) method for welds [1].
The field equations are supplemented by constitutive relationship which describes the behavior of electromagnetic materials.

For example, since it is a reflective display then light travels through the material twice, which allows much thinner cell gaps.
In addition, the smaller pixel gaps between pixels, as shown in LCOS panel performance will benefit from improvements in liquid crystal material characteristics.
LCOS microdisplays have a strong foundation from many decades of liquid crystal material development and will continue to improve with new developments in material properties.

However, for some experimental cases, such as rolling of newly developed materials, coil is not available. (2) A complicated tension control system is needed.
