The development and evaluation of various weldability tests and investigation of the effect of alloying contents on the weldability of Mn-Si high strength steels were performed using 12 experimental steels, with additions of 1.2% silicon and/or 1.8% manganese. The present paper describes the results of a tapered maximum hardness test, bead-bend tests and synthetic HAZ ductility test, which was newly proposed by the authors.<BR>From above results, the main conclusions were obtained as follows:<BR>1) From a tapered maximum hardness test, it was recognized that weld HAZ hardness was increased remarkably by manganese addition, but a little by silicon.<BR>2) As a results of the comparison of various miniatured specimens with the longitudinal bead-bend-test specimen of Kommerell type, one small type specimen was newly introduced as a substitute for the standard type.<BR>3) HAZ ductility which was obtained by the synthetic HAZ ductility test showed remarkable loss with increasing manganese contents but was almost unaffected by silicon contents.<BR>4) Intimate relationships were established between the results of a small type bead-bend test and a synthetic HAZ ductility test, especially in critical hardness values which showed unsatisfactory HAZ ductility.
