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.

The basic thought of realizing the PR in the fault diagnosis system is the data pretreatment (constructing pattern space), feature information extraction or selection of the faults (constructing characteristic space), classifiers design (constructing type space), and recognition conclusions analysis (material application).

They are the best candidates because, if it is decided to mine T tons of total material at the end of a phase, mining the geologically optimum pit corresponding to T is certainly better than mining any other pits of the same total tonnage.
