Sažetak

This study was conducted to examine the immersion effect of cooling media used after the MAG welding process on impact toughness behavior of A36 steel plate. The media used in the experiment include air, water, and ice while CO₂ shielding gas and ER70S-6 filler metal were used in the MAG process. It is also important to note that the speed of the weld material cooling process has the ability to affect the hardness and toughness of the post-welding product. The experimental results showed that the use of cooling media affected the impact properties of the welding joint. The highest toughness value was recorded in the ice cooling media with 4,38 J/mm2.
