Induction welding is a form of weld

Induction welding is a form of welding that uses electromagnetic induction to heat the workpiece. The welding apparatus contains an induction coil that is energised with a radio-frequency electric current. This generates a high-frequency electromagnetic field that acts on either an electrically conductive or a ferromagnetic workpiece. In an electrically conductive workpiece, the main heating effect is resistive heating, which is due to induced currents called eddy currents. In a ferromagnetic workpiece, the heating is caused mainly by hysteresis, as the electromagnetic field repeatedly distorts the magnetic domains of the ferromagnetic material. In practice, most materials undergo a combination of these two effects.

Nonmagnetic materials and electrical insulators such as plastics can be induction-welded by implanting them with metallic or ferromagnetic compounds, called susceptors, that absorb the electromagnetic energy from the induction coil, become hot, and lose their heat to the surrounding material by thermal conduction. [1] Plastic can also be induction welded by embedding the plastic with electrically conductive fibers like metals or carbon fiber. Induced eddy currents resistively heat the embedded fibers which lose their heat to the surrounding plastic by conduction. Induction welding of carbon fiber reinforced plastics is commonly used in the aerospace industry. [2]

Induction welding is used for long production runs and is a highly automated process, usually used for welding the seams of pipes. It can be a very fast process, as a lot of power can be transferred to a localised area, so the faying surfaces melt very quickly and can be pressed together to form a continuous rolling weld.

The depth that the currents, and therefore heating, penetrates from the surface is inversely proportional to the square root of the frequency. The temperature of the metals being welded and their composition will also affect the penetration depth. This process is very similar to resistance welding, except that in the case of resistance welding the current is delivered using contacts to the workpiece instead of using induction.

Induction welding is a form of connection using electromagnetic induction heating products include welding induction coil is strengthened. With the power of radio frequency electromagnetic fields generated high frequency power to act or work on the electrical parts. The heat is the heat resistance. This is due to the induced currents called eddy currents in the workpiece. Heating is the main cause of the division. According to the magnetic field of a magnetic domain material repeatedly. More practical Mainly through the combined effects of these two insulating materials such as plastic and can not be induced cracks. The implanted with metal or susceptors substance that absorbs energy from an electromagnetic induction coil heat loss and heat the surrounding material called the thermal conductivity [1] plastic can also be induced cracks. By embedding metal or plastic fibers, such as carbon fiber electric currents induced eddy resistively heat the fibers embedded heat loss to the surrounding plastic. By induction welding, carbon fiber reinforced plastics used in aircraft industry [2] induction welding is used for long production runs. And a highly automated process Often used for welding the seam of the pipe , it can be a very quick process. A significant amount of power can be transferred to the area. So faying surface melt quickly. And can connect together to roll continuously at the current depth. And heating so Infiltration from the surface is proportional to the inverse square root of frequency , temperature and composition of the metal being welded, they will affect the depth of the drilling process is similar to resistance welding. Except that in the case of resistance. Welding current is transmitted by contact with the workpiece, instead of using induction.
