EFD Induction was recently awarded a huge order of 16 Weldac induction tube welders from Marcegaglia. The Italian steel processing leader now looks forward to increased uptime and substantial savings on energy consumption.
This process heats metals that have already undergone significant processing. Induction annealing reduces hardness, improves ductility and relieves internal stresses. Full-body annealing is a process where the complete workpiece is annealed. With seam annealing (more accurately known as seam normalizing), only the heat-affected zone produced by the welding process is treated.
Induction annealing and normalizing delivers fast, reliable and localized heat, precise temperature control, and easy in-line integration. Induction heating treats individual workpieces to exact specifications, with control systems continuously monitoring and recording the entire process.
Induction annealing and normalizing is widely used in the tube and pipe industry. It also anneals wire, steel strips, knife blades and copper tubing. In fact, induction is ideal for virtually any annealing task.
