Understanding the Solid State Welding Machine: Process Flow and Manufacturing Excellence

A solid state welding machine, especially an induction heating type, operates on the principle of electromagnetic induction. High-frequency alternating current is passed through an induction coil, generating a rapidly alternating magnetic field. When a conductive material (like steel or aluminum tube) is placed within this field, eddy currents are induced in the material, causing it to heat up rapidly due to its electrical resistance. For welding, this localized heating brings the edges of the material to a plastic state, after which pressure is applied by squeeze rollers to forge the material together without the need for filler metal. This is a prime solid state welding example of resistance or forge welding.
