1.INDUCTION HARDENING / INDUCTION SOFTENING

INDUCTION HARDENING

Induction Hardening:

The components are heated by means of an alternating magnetic field to a temperature within or above the transformation range followed by immediate quenching. The core of the component remains unaffected by this treatment.

Case hardening process used to increase wear resistance, surface hardness and fatigue life through creation of a hardened surface layer while maintaining an unaffected core microstructure.

Advantages of Induction Hardening

  • It Helps to Optain Selective localized Hardening Without affecting the core or other sections of the part, and their properties
  • No surface Decarburization and oxidation occurs
  • Higher fatigue strength is obtained.
  • Low risk of scaling
  • Localized hardening
  • Good reproducibility of hardening process
  • Fully automatic process
  • Less harmful to the environment compared to other hardening processes

Advantages of Crack Testing:

  • AC Magnetization locates surface discontinuities
  • HWDC magnetization locates Sub-surface discontinuities
  • Accurate inspection at manufacturing speed
  • Locates defects before, during and after processing
  • Eliminates waste of machine time & labour on defective components
  • Helps pin point defect causes
  • Fully automatic process
  • Combined Magnetization. Both Longitudinal & Circular Magnetization in one setting

Circular Magnetization:

Parts are circularly magnetized by either passing the current through the part or through a central conductor inserted through the part or through a central conductor inserted through a hole in the part. This is done by clamping the part or the conductor between the contact plates. This results in a circular magnetic field in the part under test. The defects which are visible are perpendicular to the field i.e. longitudinal cracks or cracks which deviate from the longitudinal direction by not more than 45 degree. The ammeter read the amount of magnetizing current used. The current is controlled infinitely from 0 to maximum.

Longitudinal Magnetization:

Longitudinal magnetization is accomplished with the part placed between the contact plates. This magnetic field created for magnetic crack detectors is longitudinal. Detectable defects are transverse to the longitudinal field i.e. transverse cracks and cracks deviating slightly from the transverse direction. A Stateless control circuit is used to regulate the flux density.
