Friction welding, also known as friction stir welding, is a modern welding technology that has been introduced to the industry to meet the increasing demand for high quality, efficient, and cost-effective welding processes. Unlike traditional welding processes such as Gas Tungsten Arc Welding (GTAW), Friction welding involves the use of high rotational speeds and friction force to join two pieces of metals without the application of heat.
Friction welding is a process that offers substantial advantages over traditional welding processes. Firstly, friction welding produces high strength and durable welding joints due to the unique welding mechanism. This is achieved when the process forces the metals that are being joined to enter the plastic stage, hence facilitating the bond during the solidification stage. This ensures that the welded metal parts do not weaken over time.
Secondly, friction welding is an environmentally friendly process. Unlike traditional welding techniques, it does not generate harmful fumes, radiation, or waste. As such, manufacturers can save on disposals and make a positive impact on the environment.
Thirdly, friction welding is also faster and more efficient than traditional welding processes. The process allows for welding two different metals of different thicknesses and shapes at the same time, thus reducing the need for additional brazing, tacking, or preheating steps. Furthermore, the process reduces the weld cycle time resulting in a quicker and efficient welding process.
