|Abstract:||Adequate top and bottom side weld reinforcements are important for single pass double side submerged arc welded butt joints. As the shrinkage forces generated due to the solidification of top side weld reinforcements and bottom side weld reinforcements can cancel out each other to minimize angular distortions. In the present investigation it was experimentally established during submerged arc welding (SAW) that by using proper process parameters adequate bottom and required top weld reinforcements could be obtained by using single welding pass for 12mm thick square butt joints. During the experimental investigation, the first pass of welding was used for adequate bottom reinforcement and for filling up the root gap. The second welding pass was used to achieve the required top reinforcement. The first pass weld acts like a restraint to angular distortion induced due to the weld of second pass. The process parameter was optimized using the multiple regression analysis and the process was modeled using MINITAB 15 considering the effect of input parameter on the output responses in each pass of welding.|
