The heat transfer efficiency in arc welding of a plate using a current of 250 A at 20 V is 90%. The heat required to melt the material is 10 J/mm3. If the cross-sectional area of the weld joint is 30 mm2 and the travel speed is 5 mm/s, the melting efficiency (in %) is (round off to 2 decimal places)
Enter numerical value using the virtual keypad. Round off where necessary.
