| Summary: | The article presents the finding of an optimal technology for welding an oversized
construction, from an LDX 2101 duplex steel. The biggest problems are related to the occurrence
of stresses and deformations after welding. Also, depending on the parameters of the welding
regime, the structure of the material, and the amount of ferrite/austenite can also be modified.
These changes will also lead to changes in mechanical properties and corrosion resistance. The
article also presents the problems that can arise from the inadequate choice of the filler material,
cracks in the weld seam, for a heterogeneous joint, and how to make the optimal choice. |
