Opis:: The paper evaluates the effect of the surface treatment on the strength of the single‑lap adhesive joints made of the C45 steel. The samples were joined using an adhesive composition consisting of Epidian 57 epoxy resin and PAC curing agent. The study also used Greinplast mosaic plaster with a grain size of 1.0–1.6 mm as coating. The experiment was carried out for 3 variants of joints: sheet/sheet, sheet+plaster/sheet+plaster, sheet/sheet+plaster. Each variant was divided into 3 methods of surface treatment. The strength tests were carried out on the Zwick/Roell Z150 testing machine. The roughness parameters of the surface’s samples were measured using a HOMMEL TESTER T1000 profilometer.

Opis:: The aim of the study was to compare the welded and adhesive joints made of polypropylene pipes. The pipes were butt jointed. Two pipe diameters were used: ø20 mm and ø25 mm. The welded joints were made by hot gas welding, while the adhesive joints were made by two epoxy adhesive compositions. The base for both compositions was Epidian 6 epoxy resin, which was mixed with IDA and TFF curing agents in the recommended quantitative ratios. The experimental tests consisted in determination and comparison of the strength properties of the made joints; therefore, the analyzed joints were subjected to the destructive strength tests, which determined their tensile strength in accordance with the ISO 527–1 standard. On the basis of the obtained results, it was observed that welded joints obtained the highest average strength. The lowest strength was characteristic for the adhesive joints made with Epidian 6/TFF/100:27 adhesive. The obtained results were subjected to a statistical analysis, which showed that the strength of ø20 mm diameter pipe joints did not differ significantly from the strength of ø25 mm diameter pipe joints, comparing the results for each type of joint with the assumed level of confidence α = 0.05.
