Abstract
A method for shaping a part using a magnetic pulse is provided. A thin conductive layer is positioned on the part. The part is positioned between a coil and a matrix, the conductive layer being arranged between the coil and the part. An induced current, generated by the coil, is configured: to vaporize the conductive layer generating a pressure wave in the direction of the part. Additionally, the induced current is configured to accelerate the part in the direction of the matrix in association with a magnetic field generated by the coil, pressing the part against the matrix, thereby shaping the part. Further, a method for welding a part using a magnetic pulse is provided.
Claims4
A method for shaping a part made of a metal material using a magnetic pulse, comprising:
- positioning a conductive layer made of an electrically conducting material on all or part of the part to be shaped;
- positioning the part between a coil and a matrix, the conductive layer being arranged between the coil and the part;
- and
- generating an induced current by the coil, the induced current configured to vaporize the conductive layer generating a pressure wave in a direction of the part, and to accelerate the part in a direction of the matrix, in association with a magnetic field generated by the coil, pressing the part against the matrix, thereby shaping the part.
A method for welding two parts made of a metal material using a magnetic pulse, the two parts being an internal part and an external part, comprising:
- positioning the two parts relative to one another;
- positioning a conductive layer made of an electrically conducting material on all or part of the external part;
- positioning the two parts such that they face a coil, the conductive layer being arranged between the coil and the external part;
- generating an induced current by the coil, the induced current being configured:
- generating an induced current by the coil, the induced current configured to vaporize the conductive layer generating a pressure wave in a direction of the external part, and to accelerate the external part in a direction of the internal part, in association with a magnetic field generated by the coil, pressing the external part against the internal part, thereby welding the two parts to one another.
