Different types of friction weldingĪny welding process that uses friction as a way to create the bond can be termed as friction welding. As the process continues further, the heat generation also rises, and the two materials will start becoming viscous at the contact points.Īgain, the motion between the two promotes the mixing of the two parts at their contact points, creating a bond or a weld. When two materials undergo friction welding, the relative motion between each other, and the pressure applied to them generates heat at the contact points. These irregularities are enough to generate friction between their surfaces. Even if the two materials to be welded together may seem smooth to the naked eye, there are irregularities at the microscopic level. This interaction between the two surfaces results in mechanical friction. The same principle of heat generation by friction is used in friction welding, where the metal parts are made to rub against each other at extremely high speed and pressure. As you increase the pressure and speed further, you will start feeling warmer. If you rub your palms against each other, you’ll observe that your palms will become hot.
