• One of the major concerns in applying ftiction welding is the reliability of the weld quality. No reliable nondestructive test method is available at present to determine the weld quality, particularly in process of production. So, this paper presents an experimental examination and quantitative analysis for the effects of initial energy on acoustic emission (AE) relating to weld strength as a new approach which attempts finally to develop an on-line quality monitoring system design for friction welds using AE techniques. As one of the important results, it was confirmed, through initial energy effects, that AE techniques can be reliably applied to in-process strength monitoring in any type of friction welding, as the cumulative AE counts occurring during welding and cooling periods were quantitatively correlated with reliability at 95 % confidence level to the joint strength of welds, bar-to-bar (AISI 4140 to 1117 & 12L14) and tube-to-tube (AISI 1020 to 304 stainless steels).
