embedding material
2.Some popularly concerned hot Problems and fast developed techniques in present nondestructive testing field were introduced, such as on-line monitoring for pipe laying, gas Pipeline and embedding Pipes, inspection for the adhesive coating of composite material, imaging techniques and signal processing.
4.Experimental procedures are presented for laser surface treating me-thods such as alloying,cladding,embedding,and grain refining using aCW CO_2 laser. Microstructureal and X-ray analyses of the treated surfaces indicate that many strengthening effects accrue due to such a lasertreatment,so that on the surface of a low cost material an alloyed sur-face layer of superior properties is obtained.
