A weld with a triangular cross-section (fillet weld of dimensions 5 mm × 5 mm) is to be produced on a steel workpiece by a shielded metal arc welding operation using a steel electrode. If a 24 V power supply is used and the welding speed is 12 mm/s, what is the current needed? Assume the efficiency is 80% and the specific energy to melt steel is 8 J/mm3.
