mechanical properties will vary, gener-ally resulting in higher yield and tensile strengths and reduced ductility. Conclusion Matching strength is not formally defined by AWS. However, the accepted interpretation is that the filler metal tensile strength will be equal to or greater than that of the base metal. The need for matching filler metal is
