Effect of the Single Repair of Welded Joint in Steel S690QL on HAZ Properties

Maciej Różański, Tomasz Pfeifer, Wojciech Grobosz

An essential stage in the making of steel structures involves the removal of welding imperfections. Undoubtedly, an additional thermal cycle accompanying the remaking of a weld adversely affects the mechanical properties of the HAZ. The article presents the results of technological tests concerning repeated MAG-based arc repair welding on the properties of the HAZ in welded joints made of steel S690QL.
