Abstract: A method for assembling a sheet (40) and an iron-based metal part (80) comprising a step of fitting a tubular pin (10) which is open at both ends by punching through the sheet (40) with a shank of the pin with the pin being retained (10) by the sheet, wherein a pad is detached from the first sheet (40), and a flange of the pin abuts against the surface of the sheet (40) once the through-punching has been carried out, and the elastic returns of the shank of the pin (10) and the sheet (40) compress the outer surface of the shank, or by overmoulding the pin in the sheet, and subsequently a step of welding a metal tube of the pin (10) to the iron-based metal part (80) by bringing a flee end (24) of the metal tube into contact with the surface of the iron-based metal part (80) by means of electric resistance welding (90).

Abstract: The present application describes a method for attaching a first part (20) and a second part (30) for mechanical assembly to each other, the method comprising spraying a powder (10) of a ductile material onto the parts (20, 30), causing the parts (20, 30) to become attached to one another by agglomeration of this powder (10), the method comprising texturing at least one surface of one of the two parts (20, 30) onto which the spraying is subsequently carried out.
