Xa udibanisa imibhobho yentsimbi, kufuneka unikele ingqalelo kule miba ilandelayo:

Okokuqala, hlambulula ubuso bombhobho wensimbi. Ngaphambi kokuba udibanise, qiniseka ukuba umphezulu wombhobho wentsimbi ucocekile kwaye awunayo ioli, ipeyinti, amanzi, umhlwa kunye nobunye ukungcola. Oku kungcola kunokuchaphazela inkqubela phambili ye-welding kwaye kunokubangela imiba yokhuseleko. Izixhobo ezifana namavili okugaya kunye neebrashi zocingo zingasetyenziselwa ukucoca.

Okwesibini, ukulungiswa kwe-bevel. Ngokobunzima bodonga lombhobho wensimbi, lungisa imilo kunye nobukhulu be-welding groove. Ukuba ubukhulu bodonga bukhulu, i-groove ingaba nkulu kancinane; ukuba ubukhulu bodonga buncinci, i-groove ingaba yincinci. Kwangaxeshanye, ukutyibilika kunye ne-flatness ye-groove kufuneka kuqinisekiswe nge-welding engcono.

Okwesithathu, khetha indlela efanelekileyo ye-welding. Khetha indlela efanelekileyo yokudibanisa ngokwezinto eziphathekayo, iinkcukacha, kunye neemfuno ze-welding yombhobho wensimbi. Ngokomzekelo, kwiipleyiti ezincinci okanye iipayipi zentsimbi ephantsi kwekhabhoni, i-gas-shielded welding okanye i-argon arc welding ingasetyenziswa; kwiipleyiti ezishinyeneyo okanye izakhiwo zentsimbi, ukuwelda kwe-arc emanzini okanye ukuwelda kwe-arc kungasetyenziswa.

Okwesine, lawula iiparamitha ze-welding. Iiparamitha ze-welding ziquka i-welding current, i-voltage, isantya se-welding, njl. Ezi parameters kufuneka zilungelelaniswe ngokwezinto eziphathekayo kunye nobukhulu bombhobho wentsimbi ukuqinisekisa umgangatho we-welding kunye nokusebenza kakuhle.

Okwesihlanu, nikela ingqalelo kwi-preheating kunye ne-post-welding treatment. Kwezinye i-carbon high-carbon steel okanye i-alloy steel, unyango lwangaphambi kokushisa luyafuneka ngaphambi kwe-welding ukunciphisa uxinzelelo lwe-welding kunye nokuthintela ukwenzeka kweentanda. Unyango lwe-post-weld lubandakanya ukupholisa kwe-weld, ukususwa kwe-welding slag, njl.

Ekugqibeleni, landela iinkqubo zokusebenza ezikhuselekileyo. Ngethuba lenkqubo ye-welding, kufuneka ubeke ingqalelo kwiinkqubo zokusebenza ezikhuselekileyo, ezifana nokugqoka iimpahla zokukhusela, iiglavu kunye neemaski. Ngelo xesha, izixhobo ze-welding kufuneka zihlolwe kwaye zigcinwe rhoqo ukuze kuqinisekiswe ukusebenza kwayo ngokuqhelekileyo.
