Melemo ea Phaephe ea Khase e Welded ea Arc e Sebeliselitsoeng ka Metsi a Mabeli

Tlhaloso e Khutšoanyane:

Rea u amohela ho Cangzhou Spiral Steel Pipe Group Co., Ltd., moetsi le mofani ea tsebahalang oa liphaephe tsa tšepe ea carbon tse phuthetsoeng ka spiral tse boleng bo holimo. Khamphani ea rona e motlotlo ho sebelisa theknoloji e ncha ea ho phuthela ka arc e phuthetsoeng ka spiral e netefatsang tlhahiso ea liphaephe tsa seam tsa spiral tse holimo bakeng sa lits'ebetso tse fapaneng.

Ho Welsha ka Arc e Kenelletsoeng ka Helical

Sa pele, ho tjheseletsa arc e kentsweng ka metsing habeli ke mokhoa o sebetsang hantle le o theko e tlase wa ho kopanya diphaephe. Tshebetso ena e kenyelletsa ho etsa weld ka ho qoelisa phaephe ka ho e kenya ka hara flux ya granular ho sebedisa arc tse pedi tsa weld. Sena se hlahisa weld e matla le e tshwarellang e ka mamellang kgatello e phahameng le kgatello, e leng se etsang hore e be e loketseng mehala ya kgase le metsi.

E 'ngoe ea melemo e meholo ea phaephe e phuthetsoeng ka arc e koahetsoeng habeli ke ho hanyetsa ha eona mafome. Mocheso oa granular o sebelisoang ts'ebetsong ena ea ho tjheseletsa o etsa lera le sireletsang holim'a tjheseletso, e thusang ho thibela mafome le ho lelefatsa bophelo ba phaephe. Sena se bohlokoa haholo bakeng saliphaephe tsa metsi, kaha e netefatsa hore metsi a tlisitsoeng a lula a hloekile ebile a se na litšila.

Ntle le ho hanyetsa mafome, liphaephe tse phuthetsoeng ka arc tse peli tse koahetsoeng ka metsing li fana ka thepa e ntle ea mechini. Mokhoa ona o hlahisa li-weld tse tšoanang le phaephe e matla le e tšepahalang. Sena se bohlokoa bakeng sa liphaephe tsa khase ea tlhaho kaha se netefatsa hore khase ea tlhaho e tsamaisoa ka mokhoa o sireletsehileng le o sebetsang hantle ntle le kotsi ea ho lutla kapa ho hloleha.

Ho phaella moo, diphaephe tse welded ka hara arc tse qoelitsoeng ka metsing tse pedi di kgona ho mamella mocheso o feteletseng le maemo a tikoloho. Sena se etsa hore di be ntle bakeng sa ditshebediso tsa lewatle le lewatle tse ka pepesetswang maemo a lehodimo a mabe le maemo a tshebetso. Bakeng sa diphaephe tsa metsi, ho tshwarella hona ho netefatsa hore diphaephe di ka tsamaisa metsi ka katleho ntle le ho beha tshebetso kotsing.

Molemo o mong oa ho sebelisa phaephe e phuthetsoeng ka arc e habeli e kenelletseng ka metsing ke hore bokaholimo ba eona bo boreleli ebile bo botle. Sena se etsa hore e be khetho e khahlehang bakeng sa ho kenya ka holimo le ka tlase ho mobu, kaha ho bonolo ho e hlahloba le ho e hlokomela. Ho feta moo, bokaholimo bo boreleli ba thaephe bo fokotsa khohlano le ho theoha ha khatello ka har'a phaephe, ho thusa ho ntlafatsa katleho e akaretsang ea litsamaiso tsa phepelo ea khase le metsi.

Qetellong, phaephe e welded ka arc e qoelitsoeng habeli ke khetho e ntle haholo bakeng saphaephe ea peterolele liphaephe tsa metsi.

Ebang ke ho tsamaisa khase ea tlhaho kapa metsi, liphaephe tsena li fana ka matla le ts'epo e hlokahalang ho sebetsa ka mokhoa o sireletsehileng le o atlehang. Ho hlakile hore phaephe e koahetsoeng ka arc e nang le mekhahlelo e 'meli ke letlotlo la bohlokoa lefatšeng la kaho ea liphaephe.
