... as a diagnostic technique for weld quality monitoring ( Ref 15 , 16 ). An area that has received greater investigation is the spectral range of the electromagnetic radiation emission from the metal vapor/plasma plume. Monitoring this spectral range provides means to infer the quality of the laser weld process...

..., for example, linewidth and Knight shift, may change in a measurable way when the alloy changes phase. The NMR parameter then provides a signature by which to identify each phase. Second, in a two-phase mixture, two NMR signals may be observed. In such a case, quantitative information on the integrated...

... ( Ref 20 ). Detailed theoretical analysis has been performed and verified experimentally ( Ref 21 ). Good directivity is obtained by focusing the beam with a cylindrical lens to get a line source ( Ref 22 ). More complicated patterns can even be used, such as an array of lines, giving narrower band...
