Embodiment Construction

[0045] figure 1 and figure 2 Shown is a coil 10 according to a first embodiment for magnetic pulse welding of two parts 20 , 30 . Both parts 20, 30 are made of metallic material.

[0046] The coil 10 constitutes the main part of the magnetic pulse welding equipment, and the magnetic pulse welding equipment further includes a storage unit 50 and one or more switches 51 .

[0047] The storage unit 50 is suitable for storing high energy, for example on the order of tens of kilojoules (KJ).

[0048] In a preferred embodiment, the storage unit is a discharge capacitor battery.

[0049] The coil is adapted to generate a magnetic field concentrated in a defined space, which will be described later.

[0050] Two parts, called inner part 20 and outer part 30, are arranged one above the other to form a so-called overlapping area 25 in their superimposed position, which is then welded by means of coil 10 in all or part of the overlapping area . The two parts 20 , 30 are arranged s...

Abstract

The invention relates to a coil (10) for magnetic-pulse welding of parts comprising an active portion (125), one surface, referred to as the active surface (121), of which is intended to be arranged opposite one of the parts, at an area of overlap between the parts. The active surface (121) has, across the width thereof Lb, an angled profile such that the active surface is intended to have a non-zero angle in relation to a plane (XY) along which, at least at the working area, the part nearest to the active surface extends, when the parts are positioned at the coil for welding. The invention also relates to a related magnetic-pulse welding method.

Description

technical field [0001] This invention relates to the field of welding and, more particularly, to the field of magnetic pulse welding for permanently assembling parts together. The invention relates in particular to an improved embodiment of a coil for flat part welding. Background technique [0002] Magnetic pulse welding belongs to the field of impact welding methods which are able to join two metal parts by pressing them against each other in the overlapping area. The principle of this magnetic pulse welding method is mainly based on the high-speed impact on the parts by the electromagnetic force generated by the coil. [0003] Typically, systems used to implement this magnetic pulse welding method include one or more capacitors connected to a coil to generate a brief but intense magnetic field. One or more capacitors are used to store large amounts of electrical energy. The strong magnetic field generated is the result of this electrical energy being released very quic...
