pieces of 7.0-mm-thick austenitic stainless steel plate in an arc-welding
operation. The plates are joined at a 90° angle using an inside fillet
corner joint. The velocity of the welding head is 6 mm/sec. Assume the

A corner fillet weld with cross sectional area of 75 mm is made using oxyacetylene welding. Material of the welded plates is low carbon steel (Um = 10.3 J/mm'. Travel speed at which the bead is formed = 5 mm/s. Assume that only 40% of the energy generated by the torch is used for melting the metal; the rest is dissipated. If heat of combustion for acetylene is= 54.8 MJ/m³ , determine the volume flow rate of acetylene required to perform this OAW operation.
