INVESTIGATION PROPERTIES OF EXPLOSIVE WELDED JOINTS BETWEEN STRUCTURAL STEEL AND HIGH ALLOYED MATERIALS
In this research work are presented results of investigation properties of explosive welded joints (bondings) between structural steel and high alloyed materials. As base material was used SA 516 Gr 70 structural steel, while AISI 316L austenitic stainless and nickel base alloy Inconel 825 were used as cladding materials.
Performed investigation can be divided as investigation of plates for welding before explosive welding and investigations of welded joints after performed welding. Chemical, mechanical (tensile testing, shear testing, hardness measurement and impact toughness) and microstructural investigations were performed of base metal plates. Welded joints were investigated after heat treatment of cut pieces from welded plates and chemical treatment of bended specimens in acid solution.
Obtained results from testing were compared with the standard requirement. Generally, obtained results correspond pretty well with standard requirement.
