Abstract: When friction-stir welding steel sheets, for the rotating tool, rotation speed RS is set 100-1000 rpm, rotational torque RT 50-500 Nm, and travel speed TS 10-1000 mm/min, and HIPT (kJ/mm2) is controlled to be in a range of 0.3-1.5. The steel sheets that are used have a composition including 0.01-0.2 mass% of C, 0.5-2.0 mass% of Mn, 0.6 mass% or less of Si, 0.030 mass% or less of P, 0.015 mass% or less of S, and 0.0060 mass% or less of O, with a content of Ti [%Ti] and a content of N [%N] being restricted in relation to the HIPT, Ceq being 0.5 mass% or less, and the balance being Fe and incidental impurities. As a result, local change in the frictional heat and plastic flow generated by friction can be prevented, yielding a weld portion with uniform and good toughness.

Abstract: Esta soldadura por puntos indirecta es para soldar miembros que incluyen por lo menos dos láminas de acero superpuestas que tienen una fase de ferrita como una fase principal al sujetar un electrodo de soldadura (23) contra una lámina de acero (21) desde un lado mientras se aplica presión con el electrodo (23), acoplar un punto de alimentación (24) a una lámina de acero (22) en el otro lado en una ubicación remota desde el electrodo (23), y permitir que fluya corriente entre el electrodo (23) y el punto de alimentación (24). Esta soldadura incluye poner en contacto cuerpos rígidos magnéticos (26-1, 26-2) con un área periférica del electrodo (23) desde dicho un lado contra el cual se sujeta el electrodo (23) y asegurar una región superpuesta en el área periférica del electrodo (23) mediante una fuerza magnética producida por los cuerpos rígidos (26-1, 26-2), obteniendo de ese modo una soldadura que tiene una resistencia plenamente satisfactoria, independientemente de la rigidez de los miembros.
