Induction Pressure Welding
A process where joining partners are inductively heated and subsequently upset under axial pressure. It enables short cycle times in the mass production of rotationally symmetric components.
Induction pressure welding heats the joint contactlessly via an inductive field until the material becomes plastic. Then you press the parts together with axial pressure so that they bond cohesively. The heat is generated directly in the component, making the process well-suited for pipes and profiles. It is important that the joint surfaces are clean and heating is uniform across the cross-section, otherwise you get cold spots or overheating. Pressure must be maintained until the joint is fully formed, and you should keep an eye on process time to avoid a coarse grain structure.
