Abstract: A coil to magnetic-pulse weld tubular parts including an active portion having an active surface which is arrangeable to face an area of overlap between the tubular parts. The active surface defines a tubular opening oriented in an axial direction. The active surface has a predetermined axial length. The tubular opening has, in the axial direction, along the axial length of the peripheral surface, two sections having a constant cross-section. The two sections are connected therebetween by a section having a continuously increasing cross-section. A related magnetic-pulse welding method is also provided herewith.

Abstract: A coil to magnetic-pulse weld parts including an active portion, one surface of which is referred to as an active surface, is arrangeable to face one of the parts at an area of overlap between the parts. The active surface has, across the width Lb thereof, an angled profile such that the active surface has a non-zero angle in relation to a plane. At least at the working area, the part closest to the active surface extends along the plane, when the parts are positioned at the coil for welding. A related magnetic-pulse welding method is also provided herewith.
