The shortage of resources takes their toll in product development. This means for the drive engineering that the power density has to increase and the manufacturing costs have to decrease. So, the parts and assemblies have to become smaller, while the performance should rise. Following this trend, the joining technologies cannot stand still. At the drive engineering, the elementary press fit (PF) for shaft-hub joints (SHJ) is well known. Its manufacturing is easy and cheap. As a disadvantage, the joint strength is limited due to the coefficient of friction and the maximum possible allowance for interference. Through the combination of an elementary PF with local firmly bonded pressure-soldered joints (PSJ), it is possible to increase the joint strength up to three times of elementary PF by keeping his advantages. For the so-called press fit/pressure-soldered joint (PF/PSJ), it is essential to coat one or both joint areas with a low-melting metal (solder). The main connection is the press fit based on a joint pressure at the joint area. This pressure can be used to generate PSJs (secondary connection). On one hand, the joining area is activated by cracking the oxide layers and on the other hand the inner and outer parts being approached at the distance of influence of atomic forces. The attributes of PF/PSJ are explained with the development of local PSJ at the micro contacts. If the connection will be overloaded (mechanical training), the relative movement causes deformations at the roughness peaks and effects frictional heat. This enhances the size and number of PSJs and increases the joint strength significantly. Another way to increase the transmittable torque is thermal training. With increasing temperature and time, while heating up the shaft-hub joint, the total area of PSJs grows up and a higher torque can be transmitted. The value of contact pressure is just as crucial for the development of PSJs as the temperature, the joining procedure, and the training process.
