The present paper evaluates the effect of joining method on the strength of joint assemblies of selected structural materials: DX51+Z275 galvanised steel, OH18N9 stainless steel and DC01 low carbon steel. The objects of the study are: the lap adhesive joint and the butt welded joint with continuous and spot weld. Welded joints were produced latter by means of one of the two welding methods, MIG or MAG. The choice of the welding method depended on the type substrate material. Welding was conducted at the following constant technological parameters: strength of current, electrode deposition rate, filler metal diameter, type and flow rate of shielding gas. The adhesive joint was bonded with Epidian 53/Z1/100:10 epoxy adhesive. The substrates were pre-treated in a three-stage surface preparation process involving: mechanical treatment with P60 and P320 abrasive tools and degreasing with Loctite 7063 degreasing agent. The tensile strength tests, conducted under the study, provided strength characteristics of the tested joint assemblies, indicating differences in the values of strength that depended on the applied joining method or, in the case of welded joints, the structure of the seam.
