In an arc welding operation, a groove weld has a cross sectional area = 0.045 in^2 and is 10 in long. (a) what quantity of heat (in btu) is required to accomplish the weld, if the metal to be welded is medium carbon steel? (b) how much heat must be generated at the welding source, if the heat transfer factor = 0.9 and the melting factor = 0.7? [tm for medium carbon steel = 3060 r]
