Medium-vacuum electron beam welding

EB welding in rough vacuum uses a lower vacuum level than classic electron beam welding to shorten pump-down time, speeding up the welding process.

Physical-Chemical Working Mechanism

EB welding in rough vacuum uses a lower vacuum level than classic electron beam welding. This shortens pump-down time and speeds up the welding process.

Metallurgical Relevance & Risks in Welding

The reduced pump-down time can lead to lower degassing of the metals, which can impair weld quality. There is also a risk of porosity and uneven weld penetration.

Workshop Practice & Action Instructions

For EB welding in rough vacuum, set the chamber vacuum to about 10^-3 mbar. Keep weld time under 2 seconds to ensure optimal weld quality.
