Friction Welding

Friction is an inevitable reaction when two objects rub against each other. The concept of friction welding uses this natural phenomenon in a way that reflects the properties of it in a good way. Rather than fighting the laws of nature this particular process embraces it and the welding is easier and more effective because of the amount of friction that is present.

As the two items are rubbing against each other there is heat generated. This is the result of the energy that is transferred while that rubbing is taking place. Generally with friction welding one of the objects is stationary while the second one is moving. Some objects generate more friction than others based on the design of them and the materials. The speed of the movements can also affect the amount of heat that is generated from the friction as well.

Due to the amount of friction present in welding the process is usually completed in just a couple of minutes. It will depend on the particular welding project that is at hand though. The heat is very hot and the materials including metal can liquefy and then solidify again. While they are in the liquid stage they will be joined together so that the two separate pieces become one. Generally there is some of the first one slid inside of the second one so there will be overlapping that isnt visible.

Even if the type of materials being welded are different the friction allows it to be accomplished. It can take longer though due to the differences in the point where each one of the melts enough for the process to completely take place. It does take time to learn how to effectively friction weld especially when the materials are different from each other. Yet it can be accomplished if a person has a good teacher and plenty of supervised training.

As with any type of welding, this should only be done if you know the process. Even seasoned welders should still take all of the safety precautions into consideration. Wearing protection for the arms and the eyes will help ensure there arent injuries from the heat or from the glare of the flame used.
