An arc welding process is used to fillet weld a T-joint between two steel plates. The fillet weld has a cross sectional area of 160 mm2. The unit energy for melting Um is 10 J/mm3. The heat transfer and melting factors are 0.9 and 0.6, respectively. The arc welder can provide 5000 W of power. Calculate the travel speed in mm/sec. Answers are rounded to 2 decimal places
