Abstract
A method for fabrication of a part intended to be welded including a step for forming an oblique wall between two perpendicular surfaces capable of reducing the contact surface of the face to be welded.
Claims12
A method for fabrication of a timepiece component comprising the following steps:
- forming a first part made from metal and a second part made from silicon or ceramic;
- mounting a surface of the first part on a surface of the second part
- welding, by laser electromagnetic radiation, the surface of the first part mounted on the surface of the second part, in order to secure the parts to each other and to form the timepiece component;
- wherein the step of forming the first part includes the following phases:
- taking a bar;
- profile-turning the bar to form at least one diameter portion comprising a substantially vertical surface and a substantially horizontal surface and an oblique wall between the substantially vertical surface and the substantially horizontal surface in order to reduce the substantially horizontal surface to receive the surface of the second part.
