Umsebenzi wokulungiselela ngaphambi kokuba i-welding ibaluleke kakhulu njengenkqubo ye-welding, ehambelana ngokuthe ngqo nomgangatho we-welding kunye nomphumo wemveliso egqityiweyo.
1. Ukomisa i-Electrode
Injongo yokomisa i-electrode phambi kokuwelda kukususa ukufuma kwi-electrode emanzi kunye nokunciphisa i-hydrogen kwi-pool etyhidiweyo kunye ne-weld ukukhusela i-pores kunye neentanda ezibandayo.Inkqubo yokumisa i-electrodes eneentlobo ezahlukeneyo zokugquma ihluke, kwaye inkqubo yokumisa iqhutyelwa ngokwenkqubo echazwe kwincwadana yemiyalelo ye-electrode.Kunconywa ukuba wome ngokwemiyalelo yephakheji ye-electrode ye-welding ye-Tianqiao.
2. Ukucoca phambi kwe-welding
Ibhekisela ekususweni kweoli, i-rust, ipeyinti kunye namanzi kumphezulu we-groove edibeneyo kunye nendawo yayo (ngaphakathi malunga ne-50mm) phambi kwe-welding.Xa u-welding nge-alkaline electrodes, iimfuno zokucoca zingqongqo kwaye zicokisekile, ngaphandle koko ii-pores kunye nokuqhekeka okulibaziseka ziveliswa lula.Ii-electrode ze-Acid azikhathaleli kakhulu kumhlwa.Ukuba i-rust ilula kwaye umgangatho we-weld awuphezulu, ayinakususwa.
3. Ukufudumala
Ibhekisela kumanyathelo enkqubo yokutshisa ngokufanelekileyo yonke okanye inxalenye ye-weldment ngaphambi kokuba i-welding.Injongo yayo ephambili kukunciphisa izinga lokupholisa i-joint emva kwe-welding, ukuphepha ukuveliswa kwesakhiwo esinzima, kunye nokunciphisa uxinzelelo lwe-welding kunye nokuguqulwa.Yindlela esebenzayo yokuthintela iintanda ze-welding.Isidingo sokushisa kwangaphambili kunye nenqanaba lokushisa lokufudumala lixhomekeke kwiipropati zesiseko sesinyithi, i-electrode esetyenzisiweyo kunye nokuthintela umgudu.
Kwizakhiwo eziqhelekileyo zeentsimbi ze-low-rigid low-carbon steels kunye ne-alloy-alloy high-high-power steels kunye namanqanaba angaphantsi kwamandla, ukufudumala kwangaphambili akufuneki.Nangona kunjalo, kwizakhiwo ezinobulukhuni obuphezulu okanye i-weldability engafanelekanga ejongene nokuqhekeka, ukufudumala kwangaphambili kuyafuneka ngaphambi kwe-welding.Izinto zokuwelda ezinomgangatho ophezulu we-thermal conductivity, ezifana nobhedu, i-aluminium kunye ne-alloys yazo, ngamanye amaxesha zifuna ukushisa kwangaphambili, okunokunciphisa i-welding yangoku kunye nokwandisa ubunzulu bokungena, kwaye kuququzelele ukudibanisa kwentsimbi ye-weld kunye nesiseko sesinyithi.
Kufuneka kucaciswe ukuba i-welding ye-preheat ayikona nje ukusetyenziswa kwamandla, imveliso ephantsi, kodwa kunye neemeko ezimbi zabasebenzi.I-Welding kufuneka yenziwe ngaphandle kokufudumala okanye ukushisa okuphantsi kweqondo lokushisa xa kunokwenzeka.Ukusetyenziswa kwee-electrode zohlobo lwe-hydrogen ephantsi kunokunciphisa ubushushu bokufudumala, ngenxa yokumelana nokuqhekeka kwayo okulungileyo, kodwa umxholo wamanzi we-electrode kufuneka ube phantsi kakhulu.Ngethuba nje kuvunyelwe, i-electrode inokukhethwa ngokomgaqo wokudibanisa okuphantsi, oko kukuthi, amandla ensimbi egciniweyo angaphantsi kwesiseko sesinyithi, kwaye iplastiki kunye nokuqina kwe-electrode kungcono kunoko. yesiseko sesinyithi se-welding, ukwenzela ukuba ukushisa kwe-preheating kungancitshiswa okanye kungabikho ukutshisa kwangaphambili kungasetyenziswa.
