Welding - Acceptance inspection of electron beam welding machines Part 3: Measurement of beam current characteristics
出版:International Organization for Standardization

专家解读视频
This standard is intended for use when the beam current of electron beam welding machines complying with EN ISO 14744-1:2000 is to be measured in connection with an acceptance inspection. It provides essential information on the procedure and apparatus to be used for making the measurements.The beam current is one of the significant parameters in electron beam welding. When the beam current impinges on the workpiece, it 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 beam current are within these limits.
