Impeder ferrite rods core used for erw tube manufacturing, ferrite welding rods, in high frequency tube welding process, mild steel strip of specific width is passed
through several sets of steel rolls. The steel strip is converted into an open seam tubular shape. At
this stage, the tubular shape is passed through a high frequency induction coil. The coil works as a
primary and the open seam tube acts as one turn secondary. The induced current density is highest
at the edges and results into rapid heating of these edges. The subsequent pressure rolls press the
open red hot seams together to form a butt weld joint. Ferrite rods kept inside the tube aid the
process of welding by improving its efficiency.
