Abstract

The metallurgical continuity of an ASTM A 36 steel with edge preparation at different angles was determined. Non-destructive tests were used, such as liquid penetrant, ultrasound and radiography, as well as deformations when being welded with electrode E 7018 and 30° and 35° bevels. The imperfections and discontinuities found in the weld were obtained, referring to the design, metallurgical behavior and welding process, where the latter was the one that had the greatest impact on the joint. Finally, with a longitudinal wavelength of 4376.78 m/s and a superficial one of 2884.49 m/s, it was found that in the 30° bevel there are two longitudinal cracks at a length of 9.6 mm and 1.3 mm deep, in addition the 35° bevel showed a lack of penetration of 1.25 mm
