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.
