In linear gas tungsten arc welding of two plates of the same material, the peak temperature T (inK) is given as T = c1q / α,where q is the heat input per unit length (in J/m) of weld, α is the thermaldiffusivity (in m2/s) of the plate materials and C1 is a constant independent of process parametersand material types. Two welding cases are given below.Case I: V = 15 V, I = 200 A, v = 5 mm/s, k = 150 W/mK, ρ = 3000 kg/m3, C = 900 J/kg-KCase II: V = 15 V, I = 300 A, v = 10 mm/s, k = 50 W/mK, ρ = 8000 kg/m3, C = 450 J/kg-Kwhere, V is welding voltage, I is welding current, v is welding speed, and k, ρand C refer to the thermal conductivity, the density and the specific heat of the plate materials,respectively. Consider that electrical energy is completely converted to thermal energy. All otherconditions remain same.The ratio of the peak temperature in Case I to that in Case II is
