A single full penetration weld pass is made on a thin steel plate using a power input of 4 kW, and welding speed 10 mm/s, resulting in a heat transfer efficiency of 85%.The material has a specific heat per unit volume ρc of 0.005 J/mm3-oC and thickness 5 mm. If the ambient temperature is 25 oC, and the melting temperature of the material is 1500 oC .Determine: a) the peak temperature at a distance of 1.0 mm from the weld fusion boundary b) the heat affected zone size.
