The effects of welding groove angle and geometry on mechanical properties of armor material

The purpose of the study is to examine the effects of welding groove angle and geometry on mechanical properties such as tension, compression and bending strength of butt-welded armor steel. Armor steel plates used in the study were prepared using `?V?? and `?X?? type welding geometries and three different types of groove angles and they were welded by MIG welding technique. Tension, compression and three-point-bending tests of welded joints are performed and tensile properties, bending and compression strength of the welded plates were examined. The effects of welding parameters such as welding groove geometry and welding groove angle on tension, compression and bending strength were studied numerically using finite element analysis (FEA). Three-dimensional, elastic-plastic finite element method through software MSC. MARC was applied to determine the strength of armor steel. The experimental and FEA findings are found consistent.KEYWORDS: Armor steel, tension and compression strength, MIG welding method, mechanical properties.
