Kuwotcherera kwa Arc ndi njira yomwe imagwiritsidwa ntchito kwambiri popanga mapaipi, makamaka pazogwiritsa ntchito madzi apansi panthaka. Komabe, monga njira iliyonse yamakampani, imabwera ndi zovuta zake. Mu blog iyi, tiwona zovuta zomwe timakumana nazo panthawi yowotcherera mapaipi ndikupereka mayankho ogwira mtima kuti titsimikizire kuti chinthu chapamwamba komanso cholimba chapangidwa.
Fakitale yathu ili ku Cangzhou, m'chigawo cha Hebei ndipo yakhala ikutsogola kupanga chitoliro kuyambira 1993. Ndife onyadira kugwiritsa ntchito luso lazowotcherera la spiral submerged arc, lomwe limatsimikizira kuti zogulitsa zathu ndizapamwamba komanso zolimba. Ukadaulo wotsogola uwu wapangidwa kuti ukwaniritse miyezo yapamwamba kwambiri yamadzi apansi panthaka, kupanga mapaipi athu kukhala njira yodalirika komanso yokhalitsa kwa ntchito zosiyanasiyana.
Mavuto Odziwika a ArcWelded Chitoliro
1. Ubwino wowotcherera wosagwirizana: Limodzi mwamavuto omwe amapezeka kwambiri pakuwotcherera kwa arc ndikukwaniritsa kukhazikika kwa weld. Kusiyanasiyana kwa kulowetsedwa kwa kutentha, kuthamanga kwaulendo, ndi ngodya ya electrode kungapangitse kuwotcherera kofooka kapena kosakwanira.
Yankho: Kukhazikitsa njira zowongolera zowongolera komanso kugwiritsa ntchito makina owotcherera okha kungathandize kusasinthika. Kuphunzitsa owotcherera pafupipafupi pazochita zabwino komanso kugwiritsa ntchito ukadaulo wapamwamba wowunikira kungathandizenso kuwongolera bwino.
2. Kusintha ndi kupindika: Kutentha komwe kumapangidwa panthawi yowotcherera kungapangitse kuti chitoliro chigwedezeke kapena kufooketsa, zomwe zimapangitsa kuti zikhale zolakwika komanso zolephera zomwe zimagwiritsidwa ntchito.
Yankho: Kutenthetsa chitoliro musanawotchererane ndi kugwiritsa ntchito njira zoyenera zomangira kumachepetsa kupotoza. Kuonjezera apo, kugwiritsa ntchito njira zowotchera ma pass-multi-pass kungathandize kugawa kutentha mofanana, kuchepetsa chiopsezo cha nkhondo.
3. Porosity ndi Inclusions: Kukhalapo kwa matumba a mpweya (porosity) kapena zinthu zakunja (inclusions) mu weld zingasokoneze kukhulupirika kwa chitoliro.
Yankho: Kuwonetsetsa kuti malo ogwirira ntchito ali oyera komanso kugwiritsa ntchito zida zapamwamba zodzaza mafuta kumatha kuchepetsa kwambiri chiwopsezo cha porosity ndi inclusions. Kuyendera pafupipafupi zida zowotcherera ndiarc kuwotcherera chitoliron’kofunikanso kuti tikhale aukhondo.
4. Kusweka: Chifukwa cha kuzizira kofulumira kapena njira zowotcherera zosayenera, ming'alu imatha kuchitika, zomwe zimapangitsa kuti payipi isawonongeke.
Yankho: Kuwongolera kuzizira komanso kugwiritsa ntchito njira zotenthetsera kungathandize kupewa kusweka. Kuphatikiza apo, kusankha zodzaza zoyenerera zomwe zimagwirizana ndi zinthu za makolo zimatha kukulitsa kukana kwa weld kuti asaphwanyeke.
5. Kulowetsa Kusakwanira: Kulowa kosakwanira kungapangitse mgwirizano wofooka womwe ukhoza kulephera pansi pa kupanikizika.
Yankho: Kusintha magawo azowotcherera monga voteji ndi zamakono kumatha kukulitsa kuya kwa weld. Kuyang'ana mozama ndi kuyezetsa weld kumathandizanso kuzindikira ndikuwongolera zovuta zilizonse mapaipi asanayambe kugwira ntchito.
Pomaliza
Ku malo athu a Cangzhou, timamvetsetsa kufunikira kothana ndi zovuta zomwe zimawotcherera arc kuti zipange chitoliro chomwe chimakwaniritsa miyezo yapamwamba kwambiri komanso kulimba. Pogwiritsa ntchito luso lapamwamba la spiral submerged arc welding, timaonetsetsa kuti malonda athu sakhala odalirika komanso amatha kukwaniritsa zofunikira zosiyanasiyana, makamaka m'makina operekera madzi apansi.
Poyang'anizana ndi zovuta izi ndikukhazikitsa njira zothetsera mavuto, titha kupitiliza kupatsa makasitomala athu zinthu zabwino zomwe zimapirira nthawi. Kaya mukusowa mapaipi omanga, zomangamanga kapena ntchito zamafakitale, kudzipereka kwathu pazabwino komanso zatsopano kumatsimikizira kuti mumapeza yankho labwino kwambiri pazosowa zanu.
