A groove weld has a cross-sectional area = 0.045 in2 and is 10 inches long. (a) What quantity of
\r\nheat (in Btu) is required to accomplish the weld, if the metal to be welded is medium carbon steel?
\r\n(b) How much heat must be generated at the welding source, if the heat transfer factor = 0.9 and the
\r\nmelting factor = 0.7?
