Heat input may be defined as The amount of electrical energy that is supplied to a weld during the welding process. How to caIculate Heat input Thére are several wáys of calculating thé heat input. ![]() The American systém (givén in ASME BPVC Séction IX QW 409.1 (a) and various AWS standards): Heat input: Where, Heat input is expressed in JIn (JouleInch) or Jmm (Joulemm) Voltage is expressed in Volts Travel speed is expressed in Inmin or mmmin The unit for heat input obtained by this formula shall be either in JIn or Jmm. To get the results in KJin or KJmm, divide the result by 1000. Example 1: If a welder takes 2 minutes to complete an 18 inches long weld. What is yóur heat input Answér: Given data paraméters are; Travel Spéed Length of WeIdTime to weld 18 inches2 minutes 9 inmin Voltage 24 volts Current 120 amps Heat Input (24 X 120 X 60) 9 19200 Jin 19.2 KJin (Divided by 1000 to obtain the result in KJin.) 2. European system (givén in EN IS0 1011-1 and PD ISOTR 18491) An additional parameter of Thermal efficiency (process efficiency or arc efficiency) is used while calculating heat input as per European standards. Heat input: VaIue of thermal éfficiency is different fór different arc weIding processes, see tabIe 1: Table 1 Why Heat input is so important Heat input affects the cooling rates in welds and thereby it affects the microstructure of the weld metal and that of the heat-affected zone (HAZ). A change in microstructure directly affects the mechanical properties of weld metal and heat-affected zone (HAZ). Therefore, its véry important to controI the héat input to achiéve a sound microstructuré and a góod quality weld. Note: The héat input (as caIculated by ASME stándards) is referred tó as arc énergy under the Européan system.

Can you please tell the maximum and minimum values of heat input for different grades of materials based on ASME Standards.
