Ziribe kanthu komwe cholumikizira chowotchereracho chili, kwenikweni ndi kudzikundikira kwa zochitika zowotcherera. Kwa oyamba kumene, malo osavuta ndi masewera olimbitsa thupi, kuyambira ndi kuzungulira kenako kupita ku masewera olimbitsa thupi.
Mnzake wa kuwotcherera kokhazikika mu kuwotcherera kwa mapaipi ndi kuwotcherera kozungulira. Kuwotcherera kokhazikika kumatanthauza kuti cholumikizira chowotcherera sichingasunthe payipi ikatha. Panthawi yowotcherera, malo awotcherera amasintha (mozungulira, molunjika, mmwamba ndi pansi).
Kutembenuza khomo lowotcherera kumatanthauza kutembenuza doko lowotcherera panthawi yomwe kuwotcherera kuti wowotchererayo azitha kuwotcherera pamalo abwino (amodzi opingasa, ofukula, mmwamba, kapena pansi).
M'malo mwake, kunena mophweka, zolumikizira zowotcherera zokhazikika zimakhala zowotcherera pamalopo, zomwe zimafanizidwa ndi mapaipi opangidwa kale.
Chowotcherera chokhazikika chimatanthawuza kuti chitoliro sichisuntha ndipo wowotcherera amawotcherera mozungulira. Makamaka powotcherera m'mwamba, njira yowotcherera imakhala yovuta kugwira ntchito, imafuna luso lapamwamba lazowotcherera, ndipo imakonda kufooka. Nthawi zambiri amamangidwa pazithunzi zapaipi;
Doko lozungulira limalola chitoliro kuti chizizungulira, ndipo malo ake owotcherera amakhala athyathyathya kapena kuwotcherera molunjika. Kuwotcherera ndikosavuta komanso kumakhala ndi zolakwika zochepa. Amamangidwa pansi kapena pansi.
Poyang'anira kuwotcherera, kuti tipewe madoko onse ozungulira kuti asasankhidwe kuti awonedwe ndikukwaniritsa chiphaso chachikulu, pamafunika kuyang'ana mwachisawawa gawo lina la madoko okhazikika kuti muwonetsetse kuti payipi yonseyo ndi yabwino. "Pressure Pipeline Safety Technical Supervision Regulations-Industrial Pipelines" imati chiŵerengero cha kuzindikirika kwa malo olumikizirana okhazikika sichepera 40%.
Nthawi zambiri, timagwiritsa ntchito doko lokhazikika ngati doko losunthika. Doko losunthika ndi cholumikizira chowotcherera chopangidwa kale cha payipi. Gawo la chitoliro likhoza kusunthidwa kapena kuzunguliridwa pamene payipi yapangidwa kale kuchokera pamalopo. Doko lokhazikika ndi khomo lolumikizidwa ndi munda, ndipo chitoliro sichingasunthe kapena kuzungulira panthawiyi.
Mapaipi a mapaipi akutali amatchedwa "malo akufa" ndipo amafuna "kuwunika kwa radiographic 100%. Mbali yowotcherera yakufa ndiyovuta ndipo mtundu wa kuwotcherera sikophweka kutsimikizira.
Zida zowotcherera za Xinfa zili ndi mawonekedwe apamwamba komanso otsika mtengo. Kuti mudziwe zambiri, chonde pitani:Opanga Kuwotcherera & Kudula - China Welding & Cutting Factory & Suppliers (xinfatools.com)
Doko lakuwotcherera lokhazikika limagwirizana ndi doko lozungulira.
The kasinthasintha kuwotcherera olowa zikutanthauza kuti pa payipi prefabrication kuwotcherera ndondomeko, ndi kuwotcherera olowa akhoza zimayenda mwakufuna malinga ndi ngodya kwambiri omasuka ntchito kuwotcherera. Kuwotcherera kwabwino kumakhala kokhazikika, kotero ma welder amakonda mtundu uwu wa kuwotcherera olowa.
Komabe, zolumikizira zowotcherera za workpiece zitha kukhazikitsidwa chifukwa cha malo kapena kulephera kwa chogwiriracho chokha. Ichi ndi chotchedwa cholumikizira chowotcherera chokhazikika. Pamene anakonza kuwotcherera olowa anaika ndi welded, pali njira imodzi yokha kuwotcherera olowa. Kuwotcherera kwamtunduwu kumakhala kovuta kuwotcherera ndipo kumafunikira kuyesa kosawononga.
M'mawu ena omanga mapaipi, gawo la kuwunika kolumikizana kwa weld limafotokozedwa momveka bwino. Chifukwa ngodya za zolumikizira zowotcherera ndizosiyana, kuwotcherera pamanja kumasinthasintha, ndipo mtundu wa zolumikizira zowotcherera umakhala ndi zotsatira zina. Mwachitsanzo, zolumikizira zowotcherera zokhazikika zamapaipi achitsulo zimafuna kuti ma welder azigwira ntchito zonse, zomwe zimafuna kwambiri zowotcherera. Zachidziwikire, ali ndi njira zapamwamba komanso milingo yaukadaulo. Wowotchera wabwino alibe chidwi.
Poyang'anira ntchito yomanga, chiwerengero cha zotseguka zokhazikika ziyenera kuchepetsedwa momwe zingathere. Kumbali imodzi, imatha kuwongolera mtundu wa kuwotcherera, ndipo nthawi yomweyo, imathanso kuchepetsa kuchuluka kwa mabala ozindikira ndikuchepetsa ndalama.
