susceptibility-of-flawsUnfavorable welding direction:If the electron beam misses the gap in the root area, it will result in a poorly visibleand therefore poorlycontrollable lack of fusion.Improved welding direction:The weld root is easy to monitor visually. If the rootmisses the gap, it is easyto recognize this.Electron beam weldingOften, susceptibility to flaws is already decided in thedesign construction and/or finishing design stages.Unfavorable solder position duringsoldering:The soldering gap is difficult tosee on the reverse side. This makes it difficult to monitor thepenetration of the solder (arrow). Soldering
