GB/T 46075.4-2025 Acceptance inspection of electron beam welding machines—Part4：Measurement of welding speed

Scope

This document specifies the process and instrument requirements for measuring the welding speed of electron beam welding machines.
Note: Welding speed, as one of the important parameters of electron beam welding, is used to check the speed of translation and rotation movements during the welding process, in order to determine whether the movement of the workpiece or welding gun during the welding process meets the relevant requirements.
This document is applicable to the welding speed measurement method during the acceptance of electron beam welding machines, as well as the measurement and inspection of long-term use of welding machines (including but not limited to periodic inspections).
