INFLUENCE OF ROBOTIC HARDFACING PARAMETERS ON PROPERTIES OF THE S355 STRUCTURAL STEEL S355 FABRICATED ELEMENT

Abstract

In this work, experimental welding of the consumable material SG2 layer per layer on a plate of structural steel with the aid of robots was carried out. Three samples were created with different parameters and welding directions. The obtained welded joints were visually tested, macro cross-sections were examined, and tensile testing, bending, and impact energy tests were performed. The experiment found that parameters such as lower current and voltage with the optimal welding speed and the alternating welding direction significantly influence the mechanical properties of the material and geometry of the material.
