Induction preheating in the electrotechnical industry
EFD Induction offers induction equipment, which performs a variety of preheating tasks within the electrotechnical industry. Some examples are induction preheating of axles and frames before welding, and heat softening of bars before bending.
The purpose of preheating is to reduce the risk of cracking and hardening structures. Induction allows accurate heat control—time and time again. You get exactly the result you require. What’s more, the heat is generated directly in the material, which allows you to speed up the preheating process.
