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.

A coil to magnetic-pulse weld parts, comprising an active portion, of which an active surface is arrangeable to face one of the two parts, in a working zone of an overlap zone of the two parts, wherein the active surface has, over its width, an inclined profile such that the active surface exhibits a non-zero angle relative to a plane along which extends, at least in the working zone, a part closest to the active surface when the two parts are placed in the coil for magnetic-pulse welding.
A method for magnetic-pulse welding of two parts, comprising the steps of:
- arranging the two parts relative to one another to form a working zone, the two parts faces an active surface of a coil for magnetic-pulse welding the two parts such that a free end of a part closest to the active surface is closest to the active surface, wherein the active surface has, over its width, an inclined profile such that the active surface exhibits a non-zero angle relative to a plane XY;
- and
- subjecting the working zone to a magnetic field such that a pressure is exerted on a wall of one of the parts to press it against a wall of other part to provoke a permanent bonding thereof.
