Joined Part And Joined Steel Sheet
Abstract: This joined part includes: a first steel member; a second steel member; and a joined portion that is formed at a portion where the first steel member adjoins the second steel member and that includes a welding metal and a thermally affected portion. The first steel member includes a steel sheet substrate, and an Al-Fe coating formed on a surface of the steel sheet substrate. The tensile strength of the first steel member is more than 1500 MPa. In the case where a cross-section of the welding metal taken in a thickness direction perpendicular to an extension direction of the joined portion is a measurement plane, the average Cu content of the welding metal in the measurement plane is 0.03-3.00 mass%.
