Abstract: The paper presents new developments in the detection of inner and outer defects in welds by using magnetic methods. A new yoke based on permanent magnets was designed. Signals from different types of cracks, inner and outer, are measured. Difficulties arising in detection of outer defects, in thick welded parts are also discussed.

Keywords: magnetic flux leakage, crack, weld, ferromagnetic material
