  - Year 2007

  Przeprowadzono badania wpływu wybranych warunków spawania MMA pod wodą metodą mokrą na zawartość wodoru dyfundującego w stopiwie. Dzięki zastosowaniu planowania badań ustalono, że największy wpływ na generowanie wodoru ma: zasolenie wody, natężenie prądu spawania, biegunowość prądu spawania oraz zanieczyszczenie elektrody.

  - Welding International - Year 2011

  Wet welding is the most popular method of joining in water enviroment. During underwater welding, the weldability of steel is limited by the higher cooling rates and hydrogen content in weld metal. Article presents results of preliminary tests on the effects of wet welding conditions on diffusible hydrogen amount. Seven parameters were optimized using a Plackett-Burman plan to get the most relevant variables. These parameters were:...

  - Current Opinion in Green and Sustainable Chemistry - Year 2021

  Chemometric tools are widely used in analytical chemistry for the reduction of data dimensionality, grouping of variables and processing of analytical signals. They have also the potential to be applied in analytical procedure development with the aim of minimizing the procedure’s environmental impact. The design of experiment gives the possibility to obtain much better information on the system response than in case of “changing...
