Heat input formula. Amp. Volt. 60. factor / cm/min. / 10.000 = Kj/mm. EN 1011-1 (saw-1) (smaw-fcaw-gmaw-0.8) (gtaw-plasma-0.6) name: process: ASME IX: AWS D1-1: EN ISO 15614-1: WPS ranges: WPS ranges.
Thank you5.12 Heat Input Qualifications 'Heat input shall be determined using the formula: Heat Input (kJ/mm) = Amperage X Voltage X 0.06 / Travel Speed (mm/minute) or Heat Input (kJ/in) = Amperage X Voltage X 0.06 / Travel Speed (in/minute)'. H = heat flow rate (kJ/s, kW) c p = specific heat (kJ/kg o C) ρ = density (kg/m 3) dt = temperature difference (o C) This generic equation can be modified for the actual units - SI or imperial - and the liquids in use. Volumetric Water Flow Rate in Imperial Units. For water with temperature 60 o F flow rate can be expressed as. In 1-pass welding with 65 mm thic k plate, show n in Fig. 2, the w elding heat input ros e to 50-60 kJ/mm a nd the w eld w as he ld at high temperature for a long period. In this case, the cooling time (800 -500ºC) in the HAZ near the fusion line was on the orde r of 400 s. (1.3 kJ/mm) and high (2.9 kJ/mm) HI values in the diffusible hydrogen test (bead on plate) samples. Heat input, manual metal arc welding, diffusible hydrogen, travel speed, hardness, quenched and tempered steel. The heat input (HI) equation is commonly used to define the.
