  • Descrição: It is well known that fusion welding between titanium and foreign materials is almost impossible because of occurring brittle intermetallic compound in its weld metal. From this reason, there are few research reported for the welding titanium to other steels up to date. And also, there are a few investigations reported for it by using other welding process except fusion welding. In this study, to establish the welding process between titanium and SUS 304L austenitic stainless steel by using friction welding process with argon shielding, the effect of welding conditions on the tensile strength and metallurgical characteristics of the weld joint was evaluated. The results obtained are as follows: (1) There was little or no deformation observed in SUS 304L after weld. (2) The welding conditions, which increase the tensile strength, are, a. low rotational speed, b. high upsetting pressure and c. polishing of the faying surface of SUS 304L before welding. (3) Upsetting pressure was the most effective to tnesile strength than the other factors. (4) The tensile strengths of the joints, which were welded by using conditions described in (2), were from 348MPa to 378MPa. (5) The characteristics of the faying surface of SUS 304L before joining affected the tensile strength of the joint. That is, the roughness and foreign materials on the faying surface decrease the degree of metal bonding.
