Elimination of cracks in steel structures using design-technological measures

H. Herold, N. Woywode

Magdeburg University, Germany

Abstract
Numerous open and closed cracks were detected in thick-walled welded elements of span structures of a metallurgical workshop made from increased-strength steel plates 11-45 mm thick. Cracks were registered also in welds between shafts and drum bases of a belt conveyer. Explanations of formation of this type of defects are given. Design-technological measures are suggested for elimination of such cracks.
Keywords: welded structures, increased-strength steels, hot galvanizing. quenching structures, thermal stresses, preheating, groove preparation
