Feasibility Study on the Use of Leakage Flux NDT Methods for Automatic Inspection of M-42 Grenade Bodies,
Abstract
The purpose of this program was to determine, by use of laboratory setups, the effectivness of magnetic perturbation (leakage flux) techniques for locating and quantifying flaws in M-42 grenade bodies. Various magnetizing and scanning schemes were implemented in order to find surface and subsurface flaws with longitudinal or transverse orientations. Of special interest was the ability to find defects in the embossed area of the inner surface where there may be a higher probability of crack propagation. A side benefit is the possibility of ascertaining the presence and depth of the embossed area. The evaluation setups were developed about a simple bench lathe, but the eventual design goal of providing an automatic, high speed nondestructive inspection system was an overriding consideration in the design of the experiments. Some of the conceptual options for developing a production machine are presented in a later section of this report.
