Abstract
There are many papers and investigations concerning the major in uence of heat input on microstructure and mechanical properties of welded joints. However, welded joints made with the same heat input dont exhibit the same quality and properties in every case. The article presents the review of literature dealing with heat input issues and possibilities of optimization of pulsed current GTAW process parameters.

Wpływ energii liniowej na wybrane aspekty jakości połączeń spawanych elektrodą nietopliwą z zastosowaniem prądu pulsującego
Istnieje wiele opracowań naukowych, które podkreślają wpływ energii liniowej spawania na mikrostrukturę i własności złącza. Niemniej jednak znane są przypadki, gdy elementy spawane przy tej samej lub zbliżonych wartościach energii liniowej różnią się znacznie jakością. Artykuł zawiera przegląd literatury poświęconej zagadnieniom związanym z energią liniową oraz z możliwościami optymalizacji parametrów procesu przy spawaniu metodą GTAW prądem pulsującym.
