Application of LLT Probe in Testing of Welds of Thick Wall and Narrow Gap
The principle of LLT method, and practical inspection experience were introduced. Result showed that LLT method could detect defects perpendicular to the test surface with high sensitivity, but could not measure its sizing. By the combination of the Tip method and LLT method, the characteristics and sizes of defects could be analyzed.
