The essential tool for electron beam welding and processing.

Get unrivalled confidence in the performance of your electron beam system. ENG


BeamAssure by Fullagar TechnologiesMeasuring and calibrating powerful electron beams is notoriously challenging. BeamAssure makes it simple. 

This advanced QA tool independently measures and quantifies electron beams to aid manufacturing, research or maintenance planning. It captures crucial data and reveals where improvements can be made in real time, giving you assurance of your beam's consistency, even after thousands of welds. 

BeamAssure provides unrivalled confidence in the performance of your electron beam system, so you can have confidence in the integrity of your product.

What is BeamAssure?

BeamAssure is an advanced, durable probe system combining hardware and software, which measures and visually represents key characteristics of an electron beam:

  • Current
  • Asymmetry
  • Profile
  • Focus 
  • Diameter


  • Quick go/no-go ‘traffic light’ decision-making tool
  • Objectively determines beam focus settings, independently of operator/machine perception
  • Accumulates long-term process QA data
  • Not intrusive to welding
  • Measures low- and high-power beams
  • Variants for welding, additive manufacturing and processing
  • Requires no thermal management or active cooling
  • Developed and fully supported by TWI: installation, training and warranty
BeamAssure has resulted in a step change in our understanding of electron beam welding.
