engineering recuitment GATE ME 2023-24 Test Series Production Engineering (Manufacturing) Joining Welding
Submerged arc welding is performed on a 10 mm thick stainless steel producing a butt weld as shown in the figure. The weld geometry is approximated as a trapezoid with 15 mm and 10 mm at the top and bottom dimensions respectively. The voltage provided is 40 V at 400 A. The welding speed in mm/s if a stainless-steel filler wire is used.
Take unit-specific energy as 9.4 J/mm3 and heat transfer efficiency as 0.9.
Enter numerical value using the virtual keypad. Round off where necessary.
