d) A shielded metal arc-welding operation is performed at a current of 175A and voltage of 20V. The melting factor f; = 0.5 and the power can be transferred to the work surface with a heat transfer factor f= 0.9. The metal to be welded is low carbon steel, with a melting temperature of 1760K. A continuous fillet weld is to be made with a cross-sectional area of 20 mm². Determine: i) The power required in this arc-welding operation, ii) The rate of heat generation at the weld, iii) The Volume rate of metal welded,
