Overview
EN ISO 14744-4:2000 - "Welding - Acceptance inspection of electron beam welding machines - Part 4: Measurement of welding speed" (CEN) specifies how to measure the welding speed of electron beam welding (EBW) machines during acceptance inspection. The standard applies when measuring the translational and rotational speeds required for the welding operation on EBW machines that conform to prEN ISO 14744-1. It defines the essential information on the procedure and apparatus to be used for speed measurement and allows alternative standardized procedures if they provide equivalent acceptance criteria.
Key topics and requirements
- Scope of measurement: Focuses on the speed of translational and rotational movements necessary to perform electron beam welding.
- Acceptance inspection context: Intended for use during machine acceptance testing to verify performance against agreed requirements.
- Procedure and apparatus guidance: Provides essential guidance on measurement methods and the types of equipment considered suitable for speed verification (no specific proprietary equipment mandated).
- Equivalence clause: Permits alternative standardized methods provided they achieve at least the same acceptance criteria as those described in this part.
- Compliance linkage: Intended for EBW machines that comply with prEN ISO 14744-1, forming part of the broader ISO 14744 series for acceptance inspection of electron beam welding machines.
Practical applications
EN ISO 14744-4:2000 is practical for:
- Manufacturers of electron beam welding machines performing factory acceptance tests.
- Quality and test engineers verifying machine kinematics and welding program speeds before delivery.
- Inspection and certification bodies conducting acceptance inspections for compliance with EBW performance requirements.
- End users in industries requiring precise EBW control - such as aerospace, automotive, power generation, and research laboratories - who need documented proof of machine capability.
- Maintenance teams validating repaired or upgraded motion subsystems against original acceptance criteria.
