Umehluko phakathi kwepayipi lensimbi elisontekile eline-arc elicwilisiwe kanye nomthungo oqondile wepayipi lensimbi elishiselwe imvamisa ephezulu

I-arc welding engaphansi kwamanziipayipi lensimbi elivunguzayoisebenzisa i-welding wire eqhubekayo njenge-electrode ne-filler metal. Ngesikhathi sokusebenza, indawo yokushisela imbozwe ngesendlalelo se-granular flux. I-arc ye-spiral tube arc enobubanzi obukhulu iyasha ngaphansi kwesendlalelo se-flux, incibilikisa ukuphela kwentambo yokushisela kanye nengxenye yesisekelo sensimbi. Ngaphansi kwesenzo sokushisa kwe-arc ukwenza i-weld, i-flux ephezulu incibilikisa i-slag futhi isabela nge-metallurgical nensimbi ewuketshezi. I-slag encibilikisiwe intanta phezu kwechibi lensimbi elincibilikisiwe. Ngakolunye uhlangothi, ingavikela insimbi yokushisela, ivimbele ukungcoliswa komoya, futhi ikhiqize ukusabela komzimba namakhemikhali ngensimbi encibilikisiwe, ithuthukise ukwakheka nokusebenza kwensimbi yokushisela. Ngakolunye uhlangothi, ingenza futhi insimbi yokushisela Iphole kancane. I-arc welding engaphansi kwamanzi ingasebenzisa i-welding yamanje enkulu, futhi izinzuzo zayo ziyikhwalithi enhle ye-weld kanye nesivinini esiphezulu sokushisela. Ngakho-ke, ifaneleka ngokukhethekile ukushisela amapayipi ensimbi anobubanzi obungububanzi obukhulu. Iningi lazo lisebenzisa i-automated welding, esetshenziswe kakhulu ekushiseleleni i-carbon steel, i-low alloy structural steel, nensimbi engagqwali.

I-high-frequency welding iyindlela yokushisela yesigaba esiqinile. I-high-frequency welding ingahlukaniswa ibe yi-welding high-frequency welding kanye ne-induction high-frequency welding ngokusekelwe endleleni yamanje ye-high-frequency eyenza ukushisa ku-workpiece. Lapho uthintana ne-high-frequency welding, i-high-frequency current idluliselwa kucezu lokusebenza ngokuthintana ngomshini ne-workpiece. Ngesikhathi se-induction high-frequency welding, i-high-frequency current ikhiqiza i-current induced endaweni yokusebenza ngomphumela wokuhlanganisa ikhoyili yokungeniswa ngaphandle kwendawo yokusebenza. I-high-frequency welding iyindlela ekhethekile kakhulu yokushisela, futhi imishini ekhethekile kufanele ifakwe ngokomkhiqizo. Ukukhiqiza okuphezulu, isivinini sokushisela singafinyelela ku-30m/min. Kusetshenziswa ukushisa okuqinile kokumelana njengomthombo wamandla, ukushisa kokumelana okukhiqizwe yi-high-frequency current ku-workpiece kusetshenziswa ngesikhathi sokushisela ukushisa indawo yokushisela ye-workpiece ibe yincibilikisiwe noma eduze ne-plastic state, bese kuba namandla aphazamisayo. isetshenziswa (noma ayisetshenziswa) ukuze kuzuzwe ukuhlangana kwezinsimbi.
