Change in hardness, yield strength and UTS of welded joints produced in St37 grade steel


St37 is one of low carbon steels which is widely used in different industries especially for fabrication the automobile chassis and bodies. The chemical composition of this grade steel is included carbon between 0.17 and 0.2 (%wt) and due to low carbon, its weldability is appropriate. MAG equipment is one of the oldest arc welding processes which is used for joining many of metals and alloys in form of plate, sheet and pipe. Present work focuses on relationship between the robotic MAG welding variables and mechanical properties of St37 steel joints.
Keywords: MAG parameters; weld metal; mechanical properties.
