The paper presents the influence of pulsation frequency on the results of pulsed current TIG welding based on two criteria: geometric parameters of weld and changes in microstructure. The investigations were carried out for 301L austenitic stainless steel with constant current parameters, constant welding speed, 50% duty cycle ratio and constant heat input. The results were referred to the commonly used methods for measuring the amount of heat input.

W pracy przedstawiono wpływ częstotliwości pulsacji prądu na wyniki nadtapiania metalu rodzimego przy metodzie spawania TIG prądem pulsującym w oparciu o dwa kryteria: ocenę parametrów geometrycznych nadtopień oraz ocenę zmian mikrostruktury. Badania przeprowadzono dla stali austenitycznej 301L przy stałych parametrach prądowych, stałej prędkości spawania, współczynniku wypełnienia impulsu 50% i stałej energii liniowej. Wyniki odniesiono do powszechnie stosowanych metod pomiaru ilości wprowadzonego ciepła do materiału na jednostkę długości spoiny.
