I-E6013 impushana yokushisela yokwenza i-electrode yokushisela, okuwuhlobo lwe-carbon steel electrode enohlobo lwe-iron powder titania.AC/DC.I-welding yendawo yonke.Inokusebenza okuhle kakhulu kwe-welding futhi cishe ayinawo ama-spatter.Inokuvutha kabusha kalula, ukubola okuhle kwe-slag, ukubukeka kwe-welding okubushelelezi.Ibanga elivamile kanye nebanga le-rutile ongalikhetha.
Izici:
1.Isiteleka esisheshayo kanye nokushaya okulula nokususwa kalula kwe-slag
2.Ukusebenza kwe-arc okuzinzile kanye nokuphazamiseka okuncane kwe-arc
3.Ukubukeka okubushelelezi nokucwebezelayo & nezakhiwo ezinhle kakhulu zemishini
4. Ukusebenza okuphezulu kanye namanani omthelela aphezulu ku -30c.
5. Amazinga aphezulu e-deposit
6. Ukumelana nokuqhekeka okuhle kakhulu nokusebenza kwe-x-ray
7. Ukupakisha: 300kgs isikhwama damproof emaphaketheni;noma njengoba ubudinga
Qaphela:
1.I-Electrode kumele ivunywe ngu-350-380℃ ihora elingu-1 ngaphambi kokushisela, yomisa i-electrode uma uyisebenzisa.
2. Ukugqwala, amafutha, amanzi nokunye ukungcola kwe-weld kufanele kususwe ngaphambi kokushisela.
3.Kumelwe usebenzise i-arc welding emfushane, ama-swings akufanele abe mkhulu kakhulu, ukushisela ubuhlalu obuncane kufanelekile.
4. Ukuze uvimbele ukukhiqiza i-arc porosity, ipuleti le-arc kufanele lamukelwe noma lisebenzise indlela yokubuyisela yokushisela i-arc.

I-Welding electorde powder ye-E7018, E6011, E6010, E7024, njll iyatholakala.Pls xhumana nathi ukuze uthole imininingwane eyengeziwe.
Izidingo zobuchwepheshe zokucubungula:
Izingxenye zokushisela ezibalulekile kufanele zimakwe ngokucacile ngokuhambisana nemithetho efanele lapho ulungiselela imininingwane yenqubo yokushisela.
Ukuhlanganisa isikhunta (i-assembly fixture) yezingxenye ezishiselwe, inani le-welding shrinkage kufanele licatshangelwe.Kufanele kuqinisekiswe ukuthi ukubekezelelana kwezingxenye ezishiselwe kungaphakathi kwezidingo zokuklama.
Ngaphambi kokuhlanganisa, susa ukugqwala, uwoyela, uthuli kanye nomswakama endaweni engekho ngaphansi kuka-25mm ezinhlangothini zombili ze-weld.Kumashisela abalulekile ensimbi yesakhiwo se-alloy ephansi, isikali se-oxide kufanele sisuswe.
Igebe lokuhlanganisa kufanele lilawulwe ngesikhathi sokuhlanganisa.Igebe le-butt welds liyi-2 ~ 3mm, futhi igebe lamashisela e-fillet ngu-0 ~ 2mm.Uma igebe lasendaweni likhulu kakhulu, zama ukulinciphisa libe ngusayizi oshiwo.Kunqatshelwe ngokuphelele ukwengeza ama-fillers kugebe, futhi ukubhanqa okuqinile akuvunyelwe ukunciphisa ukucindezeleka okusele ezingxenyeni ezishiselwe.
Izinto zokushisela kanye nemingcele yenqubo esetshenziswa ekushiseleleni i-tack tack izofana nezidingo ze-weld ezisemthethweni.
Ukusebenza kwe-welding kungenziwa kuphela ngemuva kokuthi izingxenye ze-welding ziphumelele ukuhlolwa komhlangano.
Okwezinto ezisetshenziswayo ezintsha nezinqubo ezintsha, ukuhlolwa kwenqubo kufanele kwenziwe futhi zingasetshenziswa kuphela ngemva kokuba seziqeqeshiwe.
I-slag yokushisela kanye nokukhubazeka empandeni ye-weld kufanele kususwe ngaphambi kokushisela i-weld ehlanekezayo ye-weld kanye namanye ama-weld a-grooved.
I-Welding ingenziwa kuphela ngemva kokuhlanza.
Ngaphambi kwe-welding, akuvunyelwe ukuqala ukuthungela kwe-arc nokuhlola ukulungiswa kwamanje endaweni engashisi.Ngemuva kwe-weld, ubuso be-weld kufanele buhlanzwe futhi bomiswe.
I-Net, yezingxenye ezibalulekile ze-welding zezingxenye ezibalulekile zokushisela, uphawu lwe-welder kufanele luphawulwe endaweni efanele ngemva kokushisela.
Kumapuleti ensimbi anogqinsi lwe-0.3 ~ 4mm, izindlela zokushisela ezifana ne-gas metal arc welding noma i-argon tungsten arc welding isetshenziswa kakhulu.
Ukuze kufakwe i-welding yezingxenye zensimbi ezingafani, ama-electrode, izintambo kanye nama-fluxes wezinga elifanayo lamandla kufanele kukhethwe.
Uma welding low-alloy structural steel, akufanelekile ukuyeka phakathi, bese uzama ukuqedela ukushisela ngesikhathi esisodwa;ngesikhathi sokushisela okunezingqimba eziningi, amalunga phakathi kwezingqimba kufanele anyakaze futhi izinga lokushisa phakathi kwezingqimba lilawulwe phakathi kuka-250 ~ 300℃.Ngaphambi kokushisela ungqimba olulandelayo lwe-welding seam, kufanele luhlanzwe.Hlola ukushisela kongqimba olungaphezulu ukuze uqinisekise ukuthi awekho amaphutha.
