Abstract
The paper presents the experimental research on the behaviour of EH 36 naval steel at the MAG-M mechanized butt welding in the naval field. Butt welded joint was performed in the four welding positions (PA/1G, PC/2G, PF/3G and PE/4G). In the welding process, two types of tubular wires and a mixture of active protective gases were used. The first part of the paper presents the effective welding of the four samples. The results of the non-destructive and destructive controls of the welded samples are presented below. The work is completed with the conclusions drawn from the experimental program. The good results thus obtained make it possible to apply the welding technologies of the EH 36 naval steel in the four analyzed positions.
