Welding - Acceptance inspection of electron beam welding machines - Part 3: Measurement of beam current characteristics (ISO 14744-3:2000)
This standard is intended for use when the beam current of electron beam weldingmachines complying with prEN ISO 14744-1:1999 is to be measured in connection with an acceptance inpection. 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 shall be stable and reproductible 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.
Schweißen - Abnahmeprüfung von Elektronenstrahl-Schweißmaschinen - Teil 3: Messen des Strahlstrom-Kenngrößen (ISO 14744-3:2000)
Diese Norm ist für das Messen der Strahlstrom-Kenngrößen bei Abnahmeprüfungen von Elektronenstrahl-Schweißmaschinen nach prEN ISO 14744-1:1999 anzuwenden. Sie enthält wesentliche Informationen zum Verfahren und zu Geräten für die Durchführung der Messungen. Der Strahlstrom sollte daher innerhalb definierter Kurzzeit- und Langzeitschwankungen gleichmäßig und reproduzierbar auf das Werkstück treffen. Zweck der Messung ist zu prüfen, ob die Schwankungen des Strahlstroms diese Grenzabweichungen einhalten.
Soudage - Essais de réception des machines de soudage par faisceau d'électrons - Partie 3: Mesure des caractéristiques de l'intensité du faisceau (ISO 14744-3:2000)
La présente norme internationale a pour but d'être utilisée lorsque les caractéristiques de l'intensité du faisceau de machines de soudage par faisceau d'électrons en conformité avec l'ISO 14744-1:2000 sont à mesurer dans le cadre d'essais de réception. Elle fournit des informations essentielles sur le mode opératoire et les appareillages à utiliser pour réaliser de telles mesures. L'intensité du faisceau est un des paramètres importants en soudage par faisceau d'électrons. Lorsque le faisceau atteint la pièce à souder, il convient que son intensité soit stable et reproductible, en étant comprise dans des limites à court terme et à long terme données. Ainsi, l'objet de la mesure est de vérifier si les variations de l'intensité du faisceau sont comprises dans ces limites.

Overview
EN ISO 14744-3:2000 (ISO 14744-3:2000) specifies how to measure the beam current characteristics of electron beam welding machines as part of an acceptance inspection. Intended for use with machines complying with prEN ISO 14744-1:1999, the standard gives essential guidance on the procedure and apparatus for measuring beam current. Because beam current directly affects weld penetration and quality, the standard focuses on verifying that beam current is stable and reproducible within specified short‑term and long‑term limits.
Key topics
- Scope and purpose: Measurement during acceptance inspection to ensure machines meet performance requirements for electron beam welding.
- Measurement procedure: Guidance on the steps and conditions under which beam current measurements should be made (general procedural intent is defined; specific test sequences and apparatus types are described at a high level).
- Measurement apparatus: Information on the equipment characteristics required to carry out accurate beam current measurements (the standard provides requirements for suitable measurement apparatus).
- Beam current characteristics: Emphasis on stability and reproducibility of the beam current when it impinges on the workpiece.
- Acceptance criteria: Checking that variations in beam current remain within defined short‑term and long‑term limits to demonstrate consistent welding performance.
- Documentation: Requirement to record measurement results and use them as part of the machine acceptance record.
Applications
EN ISO 14744-3 is practical and relevant to:
- Machine manufacturers performing factory acceptance tests on electron beam welding equipment.
- Quality assurance and inspection bodies verifying supplier claims and certifying machines for delivery.
- Welding engineers and process specialists responsible for process qualification and machine commissioning.
- Maintenance and calibration teams ensuring ongoing machine performance meets acceptance criteria.
- Purchasing/procurement teams requiring documented acceptance procedures as part of contracts for welding equipment.
Practical benefits include improved weld consistency, documented acceptance evidence, reduced process variability, and clearer criteria for warranty and handover.
