Document Type and Number:
Japanese Patent JP2809882
Kind Code:
B2
Abstract:
The process uses a perforated sheet (3) of a hard metal (4). Each hole (6) in this is made with a lip (5) whose end (7) projects towards the surface of the metal (1) to which it is to be added. The lips form an angle (A) with the surface of the sheet and their ends are perpendicular to the plane of the sheet (D). The sheet is pressed on to the surface of the softer metal so that the lips straighten and the metal creeps into the holes to anchor the sheet.
