(1) ho tjheseletsa arc ka metsing
Ho tjheseletsa arc ka tlasa metsi ho sebedisa terata ya phepelo e sa kgaotseng e le eleketrode le tshepe e tlatsitsweng.Welding, karolong e ka holimo holim'a sebaka tjheseletsa, koahetsoeng ka mposo ea granular flux, tukang arc ka flux mposo ya karolo e qetellang ea terata le karolo e itseng botlaaseng lintho tse bonahalang melted le thehoa weld.Tlas'a ketso ea mocheso ka har'a arc ea motlakase, karolo e ka holimo ea solder melting slag le karabelo ea metallurgical e etsahala ka tšepe ea metsi.Slag e phaphametseng holim'a bate ea tšepe e qhibilihisitsoeng, ka lehlakoreng le leng, e ka boela ea etsa letsoho le leng ho sireletsa tšepe ea weld, ho thibela tšilafalo ea moea, le ho hlahisa karabelo ea 'mele le ea lik'hemik'hale ka tšepe e qhibilihisitsoeng, ho ntlafatsa ho feteletseng le thepa ea thepa. tšepe ea weld;weld tšepe empa butle-butle Ling.The arc welding e ka tlas'a metsi e ka sebelisoa motlakase o moholoanyane.Ha ho bapisoa le welding ea arc manual, molemo o moholo ke boleng bo botle ba weld, lebelo le phahameng la welding.Ka hona, ho ke ke haholo-holo a loketse bakeng sa ho otlolohile seam tjheseletsa khōlō workpiece girth.Le ho tjheseletsa ka metjhini ka ho fetisisa.Ho tjheseletsa ka tlas'a metsi ho 'nile ha sebelisoa haholo ho tjheseletsa ha carbon steel, low-alloy structural iron and stainless steel.Li-slag tsa manonyeletso li ka fokotsa sekhahla sa ho pholisa, tse ling tsa tšepe ea sebopeho se matla haholo, litšepe tse phahameng tsa k'habone tse kentsoeng ka metsing li ka sebelisoa.

(2) ho cheseletsa ka maqhubu a phahameng
E tšoanang maqhubu tjheseletsa ke tiileng ho hanyetsa mocheso matla.Resistor mogote tjheseletsa, ho sebelisa phahameng-maqhubu a hona joale e hlahisoang ka workpiece e le hore holim'a workpiece weld zone e halefile ho ea ho qhibiliha kapa haufi le naha ea polasetiki, ka nako eo sebelisoa (kapa e sa sebelisoa) soabisa matla a ho finyella tlamahano ea. tšepe.Kahoo ke mohato o tiileng oa ho hanyetsa mokhoa oa ho tjheseletsa.High frequency tjheseletsa ho ea ka phahameng-maqhubu a hona joale ho hlahisa mocheso ka workpiece ka aroloa ka ho kopana le high-frequency welding le induction ea high-frequency welding.Ho ikopanya le high-frequency welding, high frequency current ka ho kopana le workpiece mechanical e kenang workpiece.Ho kenngoa ha high-frequency welding, high frequency current ka workpiece phello ea coupling ea coil e ka ntle ea induction ka hare ho workpiece e hlahisa hona joale.High-frequency welding ke mokhoa o matla o khethehileng oa welding, ho ea ka sehlahisoa se na le lisebelisoa tse khethehileng.Lebelo le phahameng la tlhahiso ea ho tjheseletsa ho fihla ho 30m/min.Haholo-holo sebelisoa bakeng sa ho etsa liphaephe welded longitudinal seam kapa spiral seam.
