    Kuvunguza i-welded tube i-arc welding ye-welding yamapayipi wegesi wemvelo

    Kuvunguza i-welded tube i-arc yelding yamapayipi wegesi wemvelo afakiwe isithombe
    • Kuvunguza i-welded tube i-arc welding ye-welding yamapayipi wegesi wemvelo

    Incazelo emfushane:

    I-Arc Welding iyisinyathelo esibucayi enqubweni yokukhiqiza yeKuvunguza i-welded tubeS, ikakhulukaziIpayipi lemvelo lemvelos. Kubandakanya ukusebenzisa amazinga okushisa aphezulu okwenza isibopho esiqinile, esihlala isikhathi eside phakathi kwamapayipi, kuqinisekiswe ukusebenza okuthembekile nokuhlala isikhathi eside. Kulesi sihloko, thina'I-LL ingena ngaphakathi kwezinkampani ze-Weld Welded Arc Welded Perc Ipayipi lemvelo futhi kungani'isakhi esibucayi semboni yepayipi.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    IngomaneIpayipi lemvelo lemvelos, ukuphepha kanye nokwethenjwa kubaluleke kakhulu. I-Arc Welding idlala indima ebalulekile ekuqinisekiseni ukuthi la mapayipi angamelana nezimo ezinzima ababhekana nazo ngesikhathi sokuphila kwabo kwenkonzo. Inqubo ye-welding ye-arc ifaka ukusebenzisa ugesi ukukhiqiza ukushisa okukhulu okuncibilikisa imiphetho yamapayipi futhi kubenze ndawonye.

    Enye yezinto ezibalulekile okufanele ucabangele lapho amapayipi we-arc welding we-welding yemvelo uhlobo lwendlela ye-welding esetshenzisiwe. IngomaneKuvunguza i-welded tubes, indlela esetshenziswa kakhulu yafakwa ubuchwepheshe be-arc welding (saw). Lokhu kufaka ukusebenzisa i-granular flux, okuthululelwa phezu kwendawo ye-welding ukudala umoya wokuvikela ovimbela i-oxidation kanye nokunye ukungcola ekuthinteni kwe-weld. Lokhu kuphumela egangeni elisezingeni eliphakeme, elilinganayo elinephutha elincane.

    I-Welding yePipe ezenzakalelayo

    Okunye ukucatshangelwa okubalulekile lapho amapayipi we-welding we-welding wemvelo angukukhethwa kwezinto ze-weld filler. I-Filler Material isetshenziselwa ukugcwalisa noma yiziphi izikhala noma ukungahambi kahle eWeld, ukudala isibopho esiqinile nesingaguquguquki. Ukuze uthole amapayipi we-Weld Welded, kufanele kusetshenziswe impahla ye-filler ehambelana nengane ethile yensimbi esetshenzisiwe kanye nezimo zemvelo ezivezwa yipayipi. Lokhu kuqinisekisa ukuthi iWeld ingamelana nezingcindezi kanye namazinga okushisa atholakele ngamapayipi egesi yemvelo.

    Ngaphezu kwezici zobuchwepheshe ze-Arc Welding, kubalulekile futhi ukucubungula izimfanelo nokuhlangenwe nakho kowelder okwenza umsebenzi. I-Arc Welding yamapayipi egesi yemvelo idinga amakhono aphezulu wekhono nobuchwepheshe, kanye nokuqonda okuphelele kwezinselelo ezihlukile kanye nezidingo zomsebenzi. Kubalulekile ukusebenza nabanama-welders anolwazi futhi aqinisekisiwe abangakhiqiza ama-welds asezingeni eliphakeme ahlangabezana nezindinganiso ezinzima zemboni.

    Sengiphetha, kuvunguza i-welded tube i-arc i-weldid gas yemvelo yemvelo yingxenye ebalulekile embonini yepayipi. Kudinga ukucatshangelwa ngokucophelela kwamasu we-welding, izinto ze-filler, kanye neziqu ze-welder ezenza umsebenzi. Ngokuqinisekisa lezi zinto zithola ukunakwa okufanele, kuzokwazi ukudala amapayipi wegesi wemvelo ahlangabezana nezidingo zomkhakha zokuphepha, ukuthembeka nokusebenza kwesikhathi eside.
