Imaging Plasma Channels In Electron Beam Welding

Source: PCO-TECH Inc.

During electron beam welding, the high energy concentration causes the material to melt, which forms plasma. The escaping plasma creates a channel as it “drills” into the depth of the workpiece and forms the welded seam as it cools. The sequence shown in this video has been attained using 9,000 fps with the exposure matched to the actual welding process.
