適用范圍：This standard is intended for use when the welding speed for electron beam welding machines complying with EN ISO 14744-1 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. Alternative standardised procedures can be used, provided they have at least the same acceptance inspection as the welds specified in this part 4. The measured parameter is the speed of the translational and rotational movements required to perform the welding operation. The welding speed is one of the significant parameters in electron beam welding. The workpiece or the weld point shall thus be moved at a uniform speed, in a reproducible manner, within given short-term and long-term limits. The purpose of the measurement is to check whether the variations in welding speed are maintained within these limits.
