Estudio de la aplicabilidad de tintas penetrantes no convencionales en la inspección de juntas soldadas para la detección de discontinuidades superficiales - AWS D1.1

Abstract

This project was carried out in order to determine the best combination of nonconventional penetrating inks, which have maximum applicability in the inspection of welded joints for the detection of surface discontinuities according to the AWS D1.1 code. In the methodological field, the equipment used for the experiment process is detailed, through an exploratory, descriptive and bibliographic level, allowing to define the processes based on the penetrating properties that the combinations have, based on their benefit, for which choose oils such as Sunflower and Johnson and dye such as blackberry, beetroot and achiote, in a limited time of 5 and 10 minutes, according to the specialized software. The experiment was given, through the use of unconventional inks elaborated, continuing with the evaluation in a data record, which is compared with the evaluation of conventional inks where the adequate registration was given, ending with the comparison between both results. Finally, the unconventional combinations were compared with the standardized inks, where the cracks, lack of fusion, craters, profiles, nominal sizes, undercuts and pores were visualized, where the combinations 4, 7 have the best results. , 8 and 11, which is obtained from the fusion between sunflower-annatto, as well as the Johnson-annatto mixture for 5 and 10 minutes respectively and the tabulations of the fully defined discontinuities were made, evaluating their applicability in each one of them they.
