4. What is electron beam welding (EBW)?
Electron beam welding is a fusion welding process where a focused beam of high-velocity electrons is directed at the materials to be joined. The kinetic energy of the electrons is converted into heat upon impact, melting the materials and allowing them to fuse together. EBW is ideal for applications requiring high precision, deep penetration, and minimal distortion, making it perfect for complex components and high-performance industries like aerospace and medical.

5. What are the benefits of using electron beam welding?
Precision: The ability to control the width and depth of the weld with pinpoint accuracy.
Minimal Heat Distortion: EB welding generates less heat compared to other welding methods, reducing distortion in sensitive components.
Cleaner Welds: The process is conducted in a vacuum, ensuring contaminant-free, high-purity welds.
Versatility: Can weld dissimilar metals and thin to thick materials in a single operation.

6. How long has Andrews Hi-Tec Corporation been in business?
We were established in 1984, and for over 40 years we have been a leader in the field of electron beam welding. Our president, Julian Andrews, has more than 50 years of experience in the EB welding industry.
