Abstract
For welding procedure qualification established, there are large differences in the toughness values of the weld metal compared with the values for HAZ of welds on pipes of steel P91. The paper gives an overview of possible influencing factors on the value of mechanical properties and the impact strength of welded joints in steel P91.
