Troubleshooting induction hardening problems – Part III

Many issues can be solved with quick detection and determination of problem’s cause, followed by prompt corrective action. 


In previous columns, I have provided some detail on the sources of problems with induction hardening.  While I have tried to be inclusive, there are many sources of problems with induction hardening that are not limited to quenching. In this column, I am providing a summary of the possible problems, possible causes, and a list of possible corrective actions. This list is not inclusive but should cover most of the induction-hardening related problems.

I hope that this chart will be of benefit in reducing induction hardening problems. Should you have any comments, or suggestions for future columns, please contact the author or the editor.
