Surface Preparation Method

US Patent:
3972111, Aug 3, 1976
Filed:
Mar 13, 1975
Appl. No.:
5/557977
Inventors:
Edward Dash - Long Beach CA
Assignee:
McDonnell Douglas Corporation - Long Beach CA
International Classification:
B23P 300
B23P 2500
US Classification:
29458
Abstract:
A method of preparing surfaces of metallic components which are to be adhesive bonded and spot welded is described. The faying surfaces are first prepared for adhesive metal bonding using the most modern effective solutions available for highest strength and corrosion resistance. A primer may be applied upon the faying surfaces for improved corrosion resistance. The surfaces are then abraded in selected areas for spot welding. After spot welding, a bonding adhesive is introduced along one edge of the joint and capillary action assisted by a vacuum draws the adhesive over the entire area of the joint. Alternately, after abrading the selected areas, the adhesive is applied to the faying surfaces, and the spot welding is then accomplished at the abraded areas.
