Induction welding is a sophisticated process that utilizes electromagnetic induction to generate heat and join materials. This technique involves an induction coil charged with a radio-frequency electric current, creating a high-frequency electromagnetic field. The field interacts with the workpiece, which can be electrically conductive or ferromagnetic, leading to heating through resistive eddy currents or hysteresis in magnetic domains. For non-conductive materials like plastics, susceptors—metallic or ferromagnetic compounds—are embedded to absorb the electromagnetic energy and facilitate welding.

The process is highly automated, making it suitable for extensive production runs, particularly in welding pipe seams. It's characterized by its speed, as significant power can be concentrated in a localized area, allowing the faying surfaces to melt rapidly and be united. The depth of current penetration, and thus heating, is influenced by the frequency of the current and the properties of the metals involved. Induction welding's efficiency and effectiveness have made it a staple in joining thermoplastics and composites in various industries.

The equipment for induction welding includes a power generator, typically solid-state or vacuum tube, which supplies the alternating current, a heating station with a capacitor and coil to heat the workpieces, and a cooling system. The proximity of the coil to the workpiece is crucial for energy transfer efficiency. Understanding the thermal and Newton Cooling equations is essential for optimizing the welding process, ensuring that the heat is adequately managed and the workpiece reaches the desired temperature without overheating.
