The essential tool for electron beam welding and processing


Measuring 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
