Large Diameter LSAW chitoliro khoma makulidwe ndi zinthu zake zazikulu, zabwino, ndondomeko bata, kukhala kusankha woyamba lalikulu zoweta ndi akunja mafuta ndi mpweya chitoliro ntchito.Mu lalikulu-wowongoka msoko kumizidwa arc welded chitoliro welded zimfundo, kuwotcherera ndi kutentha bwanji zone ndi zotheka kupanga mitundu yosiyanasiyana ya welded undercut, porosity, slag, kusowa maphatikizidwe, kusowa malowedwe, kuwotcherera, kuwotcherera ming'alu. waukulu mawonekedwe kuwotcherera zilema, ndipo nthawi zambiri chiyambi cha mowongoka msoko kumizidwa arc welded chitoliro khalidwe ngozi.
Miyezo kuwongolera khalidwe: 1, pamaso kuwotcherera khalidwe kulamulira 1) Choyamba, kupanga khalidwe labwino la zopangira, pambuyo podutsa anayendera pamaso mwalamulo analowa malo yomanga, ndi motsimikiza kuthetsa ntchito substandard zitsulo 2) kutsatira.kasamalidwe ka zinthu zowotcherera.Yang'anani ngati zipangizo zowotcherera pazinthu zoyenerera, zosungirako ndi zowotcha ngati zikuyenera kuchita, kaya zimatulutsa zowotcherera pamwamba zoyera komanso zopanda dzimbiri, zokutira za elekitirodi zili bwino, kapena popanda mildew.3) Apanso, kuyeretsa zone kasamalidwe ka weld.Kuyeretsa QA kuwotcherera zone, popanda madzi, mafuta, dzimbiri ndi dothi okusayidi filimu, amene kuteteza kunja kuwotcherera zilema opangidwa yofunika kwambiri.4) Sankhani njira yowotcherera yoyenera iyenera kukhazikitsidwa koyamba kuyesa kuwotcherera, pambuyo pa mfundo zowotcherera.2, kuwotcherera khalidwe kulamulira 1) malinga ndi kuwotcherera ndondomeko specifications waya ndi flux review ndi zolondola, kupewa kugwiritsa ntchito molakwa kuwotcherera waya ndi flux chifukwa cha ubwino ngozi.2) kuyang'anira kuwotcherera chilengedwe, kuchitapo kanthu zoyenera pambuyo kuwotcherera pamene kuwotcherera chilengedwe si zabwino (kutentha m'munsimu 0 ℃, chinyezi wachibale wamkulu kuposa 90%) ayenera kukhala.3) isanafike kuyezetsa woyamba kuwotcherera poyambira miyeso, kuphatikizapo danga, osamveka m'mphepete, ndi ngati ngodya ndi doko molakwika kukwaniritsa zofunika luso.4) mu njira yowotcherera ya arc mkati ndi kunja kwa zowotcherera zomwe zasankhidwa, voteji, liwiro la kuwotcherera ndi zina ndizolondola.5) kuyang'anira ogwira ntchito mu mivi yowotcherera arc mkati ndi kunja welded zitsulo chitoliro zonse mwayi mapeto mbale arc kutalika , kulimbitsa dzuwa la kuwotcherera arc pamene mbale mkati ndi kunja, amene amathandiza kusintha khalidwe kuwotcherera chitoliro umatha. .6) Kuyang'anira ogwira ntchito zowotcherera zowotcherera, kaya zatsukidwa koyamba, kaya mwakonza poyambira ngati pali mafuta, dzimbiri, slag, madzi, utoto ndi zonyansa zina.
