Most of them concerned the Koribu's thermal profile.

This is the thermal profile of a cross-section through Manna's center.

The welding cycle can be split into several stages during which the heat flow and thermal profile will be different:

Thermal capacity of the heat generator results in slow reaction whereby thermal profiles can be distorted (depends on system used)

Thus, the thermal profile and the electric field are interdependent.

To avoid the possibility of thermal shock affecting the output, the steepest slope in the thermal profile must be determined and leveled.

A thermal profile is a complex set of time-temperature data typically associated with an objected heat up and cool down.

To identify the thermal profile, several parameters need to be measured.

Each thermal profile is ranked on how it fits in a process window (the specification or tolerance limit).

To avoid the possibility of thermal shock affecting production, the steepest slope in the thermal profile is determined and leveled.
