I-AWS: SFA 5.5 E9015-B3Ii-electrode zeentsimbi ezixhathisa ukuqhekeka

I-electrode ye-hydrogen ephantsi ebeka i-2.25Cr – 1Mo weld metal, ibonisa amandla amangalisayo kunye nokumelana nokuqhekeka kumaqondo obushushu aphezulu ukuya kuthi ga kwi-575 C. Isetyenziselwa ukuwelda intsimbi engashukumiyo ye-21⁄4 Cr-1 Mo kunye neentsimbi ze-Cr-Mo-V ezingashukumiyo kwi-hydrogen phantsi koxinzelelo kunye neentsimbi ezibunjiweyo ezinomxube ofanayo nentsimbi engashukumiyo. Izicelo eziqhelekileyo ziquka ukwakhiwa kwebhoyila yomphunga, ukuwelda imibhobho yomphunga kunye ne-super-heater, izityalo zamandla, indawo yokucocisa ioyile kunye nezityalo zeekhemikhali.
