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

Abstract:

In this paper, the influence of double wire submerged arc welding parameters 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 Charpy absorbed energy of specimens is assessed using impact test at the temperature of -50°C. Testing results show that high heat input parameters will lead to low strength of welded joint. Impact toughness of fusion line is lower than that of other areas of welded joint.
