The power source in a particular welding setup generates 3,066 watts that can be transferred to the work surface with a heat transfer factor of 0.85. The metal to be welded is a medium-carbon steel which has a melt temperature of 1,700 K, or 3,060 R. The melting factor in the operation is 0.6. A continuous fillet weld is to be made with a cross-sectional areas of 25 mm2. Determine the travel speed in mm/s at which the welding operation can be accomplished
