This paper searches for optimal values of resistance welding parameters of composite wires to increase the durability of agricultural machinery shafts. The optimization parameter was chosen to be the adhesion strength of the composite coating to the base of the part. The adhesion of the composite coating to the base material was evaluated using the normal tear method. To determine the optimal modes of applying composite coatings, an active experiment was conducted using mathematical planning methods. The obtained response surfaces and graphs of equal yield lines made it possible to establish the influence level of the research factors on the optimization parameter. To analyze the influence of factors on the optimization criterion, scatter graphs with histograms were constructed, which allows to graphically determine the rational values of the selected optimization criterion – the adhesion strength of the composite coating to the base during resistance welding of composite wires. The implementation of the central composite plan 25–2 made it possible to establish the influence of the resistance welding parameters of composite wires (welding current strength; pressure on the electrodes; duration of the current pulse and pause; linear speed of the part rotation) on the adhesion strength of composite coatings to the base and determine their rational values
