FRICTION WELDING METHOD FOR ALUMINUM ALLOY MEMBER AND STEEL MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method for joining an aluminum alloy member and a steel member by a direct friction welding method without interposing an insert material or the like. ;SOLUTION: An aluminum alloy member having an Mg content of ≤3.5 wt.% is used, and the aluminum alloy member and a steel member are frictionally joined so that friction pressure P1 (MPa) and friction time T1 (sec) satisfy the following inequalities of P1≤-5×T1+50, 15≤P1≤40, and 2≤T1≤7.;COPYRIGHT: (C)2003,JPO
