The Effect of Two Wire Submerge Welding Parameters on the Properties of Welded Joint

摘要：

　　In this paper, the influence of double wire submerged arc welding parameter on the mechanical properties of high strength low alloy has been investigated.The 20mm steel plate has been welded by double wire submerged arc welding process using different welding parameters.The tensile strength of welded joints has been test.The Charpy absorbed energy of specimens is assessed using Charpy impact testing at the temperature of-50℃.Testing results show that high heat input parameters will lead to low strength of welded joint.Impact toughness of fusion line is less than that of other area of welded joint.
