Selection Of Optimum Process Parameters Of Shielded Metal Arc Welding (SMAW) To Weld Steel Pipes By Design Of Experiments
The focus of this work is to design parameters for shielded metal arc welding to ensure continuous and leak proof joints. To achieve the object an attempt has been made to selected important welding parameters. The selected welding parameters are welding current, welding speed, electrode angle and electrode angle. The selection is purely based on field expert’s suggestions, literature Survey an...
متن کاملInvestigation on Effect of Heat Input on the Microstructure and Mechanical Properties of Hadfield Steel Weld Joints in SMAW Process
In this investigation, the effect of heat input of SMAW process on the microstructure and mechanical properties of Hadfield steel weld joints was investigated. For this purpose, 4 annealed sheets with thickness 2 mm prepared from Hadfield steel and then welding applied by SMAW process with 6.75 and 11.25 kJ/mm heat input values. The evaluation of the microstructures of welding joints was condu...

متن کاملEffect of buffer layer and electrode composition on the mechanical properties of H13 steel repair welds using shielded metal arc welding
The present study investigated the effect of electrode composition and buffer layer on the microstructure and mechanical properties of H13 tool steel repair welds. Three specimens were welded applying two conditions; i.e. with and without stainless steel underlay. The microstructure of all weld metals contained the martensitic matrix with distributed chromium carbide precipitations. The microst...
