The main aim of the work is to determine the impact of regeneration of metal elements using epoxies that have been subjected to the bonding process and to determine the strength of the adhesive joints containing regenerated elements. The subject of the research was single-lap adhesive joints of sheet metal in various variants: solid sheets and sheets with a hole, which were subjected to a regeneration process by filling the defect with epoxy mass. Two types of the epoxy adhesive prepared on the basis of bisphenol A-based epoxy resin (Epidian 53) and two types of curing agent: polyamide and amine in appropriate proportions were used to make the adhesive joints and regenerate the joined elements. In order to determine the adhesive joints strength, experimental tests were carried out according to EN DIN 1465 standard. The joints made using the adhesive contains Epidian 53 epoxy resin with PAC curing agent with two regenerated holes were characterized by the highest strength. The lowest strength was observed in the case of adhesive joints made using E53/Z–1 epoxy adhesive. When E53/Z–1 was used to make adhesive joints, there was no effect of the regeneration holes on the strength of the adhesive joints. Taking into account the influence of the type of the adhesive on the strength of the adhesive joints made of C45 steel, it is concluded that better results were obtained when using E53/Z–1 epoxy adhesive.
