Compared to magnetic particle and dye penetrant inspection processes, eddy current testing systems are well suited to perform in-process inspections. In its 2000 annual survey, Quality Magazine found that only 43.9% of manufacturers were performing "in-process" inspections of parts. Today, the same survey indicates that 95% of manufacturers are doing some sort of in-process inspection. Driving this trend is the increased importance manufacturers are placing on quality. According to the current survey, the top five reasons manufacturers are making addi-tional investments in quality are: to increase productivity, to reduce scrap and rework, to increase production capacity, to reduce costs and to obtain tighter part quality standards. All of these also help to reduce warranty costs.
