<p>Device for manufacturing a projection weld connection for plate material of electrically conductive material with a method in which in one of the plates to be welded a projection of triangular cross section has been preformed.
- placing the plates in juxtaposition to overlap another,
- compressing the plates from one side at the location of the projection with a pressing unit carrying a pressure tool by which the projection is formed in the underlying plate, characterized in that the pressure tool has an elevation (6) on the surface with a length of 10 and a breadth of 1,4 millimeters and a height of 0,6 to 0,8 millimeters.
- Such that the projection has a 1,4 by 10 millimeters size at its base and extends from 0,6 to 0,8 millimeters above the plate, whereas the force applied on the pressure unit is between 300 and 1.800 Newton.</p> |
