Inertia Welding Machine

The machine is mainly used for Inertia Welding process. This type of welding is an alternative for friction welding, where the energy required to make the weld is chiefly provided by the stored rotational kinetic energy of the welding machine. These welding machines are most suitable when the process requires joining two different materials in one part.

Welding Process
The welding process involves connecting one of the workpieces to a flywheel, while the other part is stopped from rotating. The flywheel is sped up to a fixed rotational speed, thereby storing the required energy. The driving motor is freed and the work pieces are forced together by the friction welding force. This leads to abrasion of welding surfaces under pressure. As a result the kinetic energy stored in the rotating flywheel is discharged as heat through friction at the joining surface with the decrease of flywheel speed.

Uses & Applications
Some of the areas where inertia welding machines are widely used are:

• Aerospace applications
• Manufacturing application
• Metallurgy
• Joining nickel & titanium alloys
• Fabrication of steel flywheel
• Transportation industry
