SkV-F thermit welds made with inclined moulds . BR/TW(GB) experiment 21 (TM-MF-036)

In previous laboratory experiments, it was shown clearly that if SkV-F thermit welding moulds were positioned at an angle on the rail instead of vertically, lack of fusion defects normally resulted, which explained a large number of thermit failures in service, However, because of some conflicting evidence, a repeat...
