Abstract
Theoretical and experimental investigations of a contact area formation in producing adhesion-welded joints using a resistance spot welding (RSW) of mating surfaces of the parts having a pre-deposited layer of an adhesive with different reological characteristics are presented. A mechanism of influence of a boundary layer of the adhesive on the formation of contact at increasing and decreasing of compression force at the welding machine electrodes has been established. Recommendations are given for the creation of adhesive-bonded compositions having required reological characteristics to produce the adhesion-resistance spot welded joints along the adhesive layer.
Keywords: adhesion, adhesive-bonded compositions, weldbonded joints, resistance welding, boundary friction, developments
