dc.description.abstractThe use of boring machines under highly varying working conditions for long periods requires a successful joining of material couples. If the joining is not performed successfully, hard metal tips will shorten the life of the boring machine by breaking off from the steel body. In addition, these broken hard metal tips deposited in the bore will affect later boring work negatively. For this reason, the quality of joining has a great significance from the economy and efficiency point of view. In this study, joining by brazing of 0.4% C steel with 9% Co bonder mixed wolfram carbide based hard metal tip used in boring machines is investigated. Joining by brazing of wolfram carbide based hard metal tip with 0.4% C steel is made under suitable temperature and pressure using suitable dekapan. The microhardness and metalographic investigation of steel, braze, and hard metal tip has been done in the joining region. In the metalographic investigations, it has been observed that, in the internal structure and hardness values of solder, diffusion from steel to solder and from solder to steel occurs. Also element diffusion from hard metal tip to solder layer takes place.
