Patent ID: 7959057

Claim:
An assembly method, comprising: placing a part made of ferromagnetic material and a part made of paramagnetic metal material between first and second abutments; then, bringing the first and second abutments closer together so that the part made of paramagnetic material is in contact with the first abutment and with the part made of ferromagnetic material, without the part made of paramagnetic material touching the second abutment, and so that the part made of ferromagnetic material is in contact with the second abutment and with the part made of paramagnetic material, without the part made of ferromagnetic material touching the first abutment; then, moving the first and second abutments further from one another and creating a determined space between the parts, the part made of ferromagnetic material being in contact against the second abutment and the part made of paramagnetic material being in contact against the first abutment; then, supplying a first coil so as to throw and impact the parts against one another, kinetic energy acquired by at least one of the parts being sufficient for the parts to remain assembled together after the impact.
