The paper presents methods and results of the study of the coating resulting from gauze welding, and the effect of this coating on the adhesive strength depending on electrocontact welding modes, material and gauze parameters, residual stresses in coatings, and coating wear-resistance. According to the results of the analysis of calculations and experimental measurements, it was found that the thickness of the built-up layer of the metal coating depends on the grid parameters and can be calculated using the derived formulas. During electrocontact welding in modes: I = 2.0-2.1 kA, timp = 0.06 s., tpause = 0.08 s., the adhesive strength of the woven gauze (174 MPa) is 41% higher than the steel tape (102 MPa). It was found that the wear rate of the woven gauze coating (45 steel) layer is 15% lower than the wear rate of the without coating (45 steel) sample. It is shown that coatings made of tape and powders have twice as many residual stresses as coatings made of gauze. The study results were used to develop the technology for the restoration of automotive parts, which helps effectively restore parts and save on the cost of purchasing new ones.
