Embodiment Construction

[0049] Figure 1 to Figure 4 Shown is a coil 10 for magnetic pulse welding of two tubular parts 20 , 30 according to a first embodiment. Both parts 20, 30 are made of metallic material.

[0050] 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 .

[0051] The storage unit 50 is suitable for storing high energy, for example on the order of tens of kilojoules (KJ).

[0052] In a preferred embodiment, the storage unit is a discharge capacitor battery.

[0053] The coil is adapted to generate a magnetic field concentrated in a defined space, which will be described later.

[0054] The diameter of a first cylindrical tubular part, which will be called outer part 20, is substantially greater than that of a second cylindrical tubular part, called inner part 30, so that the inner part 30 penetrates the outer part 20 in use.

[0055] The two cylindric...

Abstract

The invention relates to a coil (10) for the magnetic-pulse welding of tubular parts, comprising an active portion (125) having an active surface (121) which is to be arranged opposite an area of overlap between said tubular parts, and which defines a tubular opening (12) oriented in an axial direction. The active surface (121) has a given axial length (Lb). According to the invention, the tubular opening (12) has, in the axial direction (XX'), along the axial length (Lb) of the peripheral surface, two sections (122, 124) having a constant cross-section which are connected therebetween by a section (123) having a continuously increasing cross-section. The invention also relates to a related magnetic-pulse welding method.

Description

technical field [0001] The present invention relates to the field of welding, and more particularly, to the field of magnetic pulse welding for permanently assembling parts together. In particular the invention relates to an improved embodiment of a coil for welding of tubular parts. 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 fields generated are the result of releasing this electrical energ...
