How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The paper presents the results of testing the tendency to intergranular corrosion of welded joints of dissimilar steels 12Kh18N10T and AISI 316 without heat treatment, as well as after quenching and stabilizing annealing. By welding control samples, optimal parameters of argon-arc welding were determined for pipes with a diameter of 42 mm and a wall thickness of 3.5 mm. A filler wire was selected according to Scheffler diagram.
