適用范圍：This standard is intended for use when the characteristics of the accelerating voltage of electron beam welding machines complying with EN ISO 14744-1 is to be measured in connection with an aceptance inspection. It provides essential information on the procedure and apparatus to be used for making the measurements. The accelerating voltage is one of the significant parameters in electron beam welding. When accelerating the electrons, the voltage should be stable and reproducible within given short-term and long-term limits. The purpose of the measurement is thus to check whether the variations in accelerating voltage are within specified limits.
