This study by Lozica Ivanovic investigates the effects of two different welding procedures on the impact toughness and hardness distribution in welded joints of high-strength low-alloy (HSLA) steels.

Welding Procedures:

Both procedures used the MAG (Metal Active Gas) welding method for filler and cover passes.

First procedure: Root passes were performed using the MMA (Manual Metal Arc) method.

Second procedure: Root passes were carried out using the MIG (Metal Inert Gas) method.

Experimental Findings:

In both procedures, the fracture energy values of the welded samples were lower compared to the base metal. This indicates that the welding process caused some deterioration in the mechanical properties of HSLA steel.

It was noted that welding parameters should be carefully selected to minimize these negative effects.

This study emphasizes the need to optimize welding technologies and provides a comparative analysis of the effects of different welding methods on the mechanical properties of HSLA steels.
