When cultivating the soil, one of the most important and oldest operations is turning the soil. Which is done with the help of a working machine called a plow. Its function is to turn the soil and to bury the harvest residues and to loosen the soil. The plow consists of several parts: the supporting body - which is responsible for the fact that the working machine can be attached to the tractor and thus can be transported to the desired surface for processing. The plow head is responsible for carrying the working part of the plow, which consists of the plow board and the coulters. The plow board needs to pick up the soil that is separated from the second layer and turn it over so that the harvest remains are buried and the decomposition process is accelerated. The ploughshare is the most important part of the entire plow, its basic function is to separate the soil, one layer from another. This thesis will deal with the topic of the influence of welding technology on the properties of the ploughshare, how we can extend the life of the ploughshare, what are the advantages and disadvantages of this technology, and based on these results, come to a solution on how to increase efficiency and profitability.
