Testing the Quality of Welded Joints in Thick-Walled Pipes Used in the Power Industry
Andrzej Wójtowicz, Patrycja Janiak, Santina Topolska
The article discusses tests concerning the quality of joints in relation to the service life of thick-walled pipes made of steel P355NH using the TIG welding method (141) and filler metal alloy grade SNi6625 (Inconel 625). Because of its mechanical properties, corrosion resistance and high-temperature resistance, the above-named material is commonly used in various industries. The test joints were subjected to structural, non-destructive and corrosion resistance-related tests.
