It is considered that the flash-butt welding used for long drawing of short rails needs heat tratment after the operation. And it is generally discussed whether appropriate heat treatment is necessary or not, and if so what method is to be used. This report deals experimentally with the problem from the view-point of mechanical and microscopic examinations.
According to the result of the experiment, it is desirable to practice the high temperature heat treatment at the temperatures from 800°C to 850°C which are necessary for normalization.
