Abstract
In addition to the known requirements to stability of heating spot position on an item specified in international standard ISO 14744-6, violations of adjustment of electron beam welding gun and procedure of their elimination are considered.
Keywords: electron beam welding, EB gun, triode emission system, electromagnetic focusing system, violations of axial symmetry, beam crossover, focal spot, instability of dimensions and position, welding gun adjustment
