As the concentration of Z1,2 defects associated with C vacancies [13] and/or complexes of nitrogen and carbon interstitials [14] has been found to increase with increasing nitrogen levels in epitaxial 4H SiC [14], it is possible that nitrogen affects stiffness indirectly through the formation of point defects in bulk material.

The kinetic energy of the high velocity electrons is converted in to thermal energy that melts and vaporizes the material.
When these electrons impinge on a material, they are stopped and, in the process, give up their kinetic energy.
This increases the amplitude of lattice vibration of electrons, which in turn raises the temperature of the material that is sufficient to melt and evaporate.
If we ignore the extreme values, it can be inferred that the If weld is less by 20mA from If sharp for a good weld formation in keyhole welding, irrespective of the work distance or material thickness.
