ukushisela inqubo ehlangene yohlaka lwesikhala sensimbi

Indawo yokushisela akufanele ibe nemifantu noma amaphutha.Ama-welds ayisisekelo nawesibili akufanele abe nezimbotshana ezingaphezulu, iziqeshana ze-slag, imifantu ye-arc pit, i-arc abrasion nokunye ukukhubazeka.Futhi i-weld yebanga lokuqala akufanele ibe nokuluma, hhayi okugcwele, ukushwabana kwezimpande nezinye iziphambeko.Inani lokuhlola: I-10% yezingxenye ezifanayo izohlolwa, futhi ingabi ngaphansi kuka-3;wezingxenye ezihloliwe, uhlobo ngalunye lwe-weld luzohlolwa ngo-5% ngenani lezicucu, futhi kungabi ngaphansi kuka-1;isamba sokuhlola indawo akufanele sibe ngaphansi kuka-10. Indlela yokuhlola: bheka noma sebenzisa ingilazi yokukhulisa, igeji yokushisela kanye negeji yensimbi, enokuhlolwa kokungena noma kwezinhlayiyana kazibuthe.

Impahla yokuxhuma i-welding kufanele ihambisane nesisekelo sensimbi.Lapho amamaki ensimbi amabili ahlukene eshiselwe, kusetshenziswa i-electrode noma ucingo olufana nebanga lensimbi elinamandla aphansi.Izixhumanisi ezishiselwe ngomthwalo oshukumisayo oqondile noma ukushisela kwepuleti eliwugqinsi obalulekile kufanele kusebenzise ama-electrode e-hydrogen aphansi, njenge-E4315, E4316, E5015, E5016 namanye amamodeli.Izembatho ezivimbela umlilo kufanele kube imikhiqizo ephumelele ukuhlolwa kwe-ejensi yokuhlola kazwelonke futhi iye yaba egunyazwe umnyango wezomlilo, futhi kufanele ihambisane ne-primer.Ukusebenza, ukujiya koqweqwe kanye nezidingo zekhwalithi zezingubo ezivimbe umlilo ezikhethiwe kufanele zihambisane nezinga lezwe lamanje elithi "Fireproof Coatings for Steel Structures" (GB14907-2018) kanye nezinga likazwelonke lamanje "I-Application Technology of Fireproof Coatings for Steel Structures" (CECS24) -2020).

Ukuhlolwa kwekhwalithi yomthungo wokushisela wamafreyimu esikhala kufanele kuhlangabezane nezidingo ezijwayelekile ezishiwo ku-<> (GB50205-2020).Izinga lekhwalithi le-weld lizothobelana nezinga likazwelonke lamanje “Ikhodi Yokushisela Izakhiwo Zensimbi” GB 50661 Indlela yokuhlola izothobela izinga lamanje likazwelonke “Ikhodi Yokwamukela Ikhwalithi Yokwakhiwa Kobunjiniyela Besakhiwo Sensimbi” GB 50205. Ngezinqe amashisela anogqinsi olungaphansi kuka-6mm, ukutholwa kwamaphutha e-ultrasonic akufanele kusetshenziselwe ukunquma izinga lekhwalithi yokushisela.6.Lapho ipayipi lensimbi kanye nepuleti lokuvala kanye nekhanda lekhoni lakha induku, amashisela ezinqeni kuzo zombili iziphetho amashisela okungena agcwele.
