(1) ukushisela i-arc emanzini
I-arc welding engaphansi kwamanzi isebenzisa intambo yokuphakelayo eqhubekayo njenge-electrode nensimbi egcwele.I-Welding, endaweni engaphezulu ye-weld zone, embozwe ungqimba lwe-granular flux, i-arc evuthayo ku-flux ungqimba wengxenye yokugcina yocingo kanye nengxenye yesisekelo esincibilikisiwe futhi yakha i-weld.Ngaphansi kwesenzo sokushisa ku-arc kagesi, ingxenye engaphezulu ye-solder melting slag kanye nokusabela kwe-metallurgical kwenzeka ngensimbi ewuketshezi.I-slag entantayo ebusweni bokugeza kwensimbi encibilikisiwe, ngakolunye uhlangothi, ingenza futhi isandla esisodwa ukuvikela insimbi ye-weld, ukuvimbela ukungcoliswa komoya, futhi kukhiqize ukusabela ngokomzimba namakhemikhali ngensimbi encibilikisiwe, ukuthuthukisa okwedlulele kanye nezakhiwo insimbi yokushisela;weld metal kodwa kancane Ling.I-arc welding engaphansi kwamanzi ingaqashwa i-welding current enkulu.Uma kuqhathaniswa nokushiselwa kwe-arc okwenziwa ngesandla, inzuzo enkulu kakhulu ikhwalithi ye-weld enhle, isivinini esiphezulu sokushisela.Ngakho-ke, ifaneleka ngokukhethekile ukuthungatha okuqondile kwe-seam ye-workpiece girth enkulu.Nokushisela okuningi ngomshini.I-arc welding engaphansi kwamanzi isetshenziswe kakhulu ekushiseleni i-carbon steel, insimbi yesakhiwo esine-alloy ephansi kanye nensimbi engagqwali.I-joint slag inganciphisa izinga lokupholisa, enye insimbi yesakhiwo esinamandla aphezulu, insimbi ephezulu ye-carbon steel submerged arc welding ingasetshenziswa.

(2) i-high-frequency welding
I-frequency welding efanayo ingamandla okushisa aqinile.I-Resistor welding eshisayo, kusetshenziswa i-high-frequency current ikhiqizwa endaweni yokusebenza ukuze ingaphezulu lendawo yokushisela ishiselwe ekuncibilikeni noma eduze ne-plastic state, bese isetshenziswa (noma ingasetshenzisiwe) amandla okuphazamisa ukufeza ukubopha insimbi.Ngakho-ke kuyisigaba esiqinile indlela yokushisela ukumelana.I-high-frequency welding ngokusho kwe-high-frequency current ukukhiqiza ukushisa ku-workpiece ingahlukaniswa ngokuthintana ne-high-frequency welding kanye nokufakwa kwe-welding high-frequency welding.Ithinta i-high-frequency welding, i-high frequency current ngokuthintana ne-workpiece mechanical engenayo yokusebenza.Ukufakwa kwe-high-frequency welding, i-high frequency current ngokusebenzisa i-workpiece umphumela wokuhlanganisa wekhoyili yokungeniswa yangaphandle ngaphakathi kwendawo yokusebenza kukhiqiza i-current induced.I-High-frequency welding iyindlela eqinile ekhethekile yokushisela, ngokusho komkhiqizo ifakwe imishini ekhethekile.Isivinini sokushisela sokukhiqiza esiphezulu esingafika ku-30m/min.Ikakhulukazi esetshenziselwa ukwenziwa kwamapayipi ashiselwe umthungo we-longitudinal noma umthungo ovunguzayo.
