Argon kutengesa arc, zvinyorwa uye maitiro

Argon Welding is a kind of electric arc welding. Chinhu chaicho chinonyanya kuitika pakuti kushambadzira kunoitika munzvimbo inochengetedza gasi nzvimbo, iyo inodzivirira kusvibiswa kwesimbi.

Nzvimbo iyo inobatwa nehini inodzivirira inosanganisira zvinhu zvinotevera: electrode tip and filler material, imwe nzvimbo weld uye weld zone. Argon haina ganda rinopindira remhepo inenge risingapindirani nesimbi panguva yekudonha uye inodyiswa kuburikidza nebhokisi inokosha yemoto inopisa magetsi. Maererano nezita remhepo inoshandiswa muhutano hwehutaneti, rudzi urwu rwekubatanidzwa kwezvikamu rwakatumidzwa.

Zvigadzirwa zvekushongedza argon-arc zvinosanganisira electrode isingashandisi, iyo inowanzoitwa ne tungsten. Iyi simbi inopesana ine unhu hwose hunoda uye hunhu, naizvozvo inowanzoshandiswa mumhando iyi yekudonha.

Muchiitiko ichi, chizadziro chakagadzirwa nenzira yefambo kana tsvimbo, iyo inongororwa nguva nenguva mubhati rinoshambadza panguva ino. Panguva yekushanda, iyo electrode inoitwa nenzira yebasa rakakosha, iro rinowanikwa mukati memharasi, rakagadzirirwa kupa argon gas kune nzvimbo iyo argon kushambadza arc inoitwa. Zvishandiso, zvakatarisana, zvinofanira kumirira zvose magetsi emagetsi achipfuura nepakati pemagetsi nemhepo inopisa kubva kushandiswa kweArgon.

Zvisinei, kwete chete tungsten electrode inobudiswa. Zvinogonawo kugadzirwa nesimbi isina tsvina uye aluminium. Munyaya iyi, argon yekushongedza arc yakakamurwa kuva 2 marudzi:

1. Ne electrode inopedza.
2. Ne electrode isingashandisi.

Argon kushambadza arc ishandiso uye inogadzirisa. Mukutsvaga kutengesa, chete kushandiswa kwe electrode kunoshandiswa, uye kushandiswa kwebhuku rinogona kuitwa ne electrode isingashandisi.

Iyo nzira yekugadzirwa kwehutengi ye argon-arc kushambadza.

Sezvo inert gases haiti kusangana nemasimbi, uye nokuti inowanzosvika 38% inorema kudarika oxygen inoshandiswa mukukanda, argon inokurumidza kuendesa mhepo nezvinhu zvisina kudikanwa zvisingadiwi kubva munzvimbo yeweld. Izvi zvinodzivisa kusakanganiswa kweiyo yehuidhi ye weld inoguma, iyo inonyanya kukosha unhu hwekugadzira uye unhu hwekuita.

Ikozvino magetsi inopfuurira kuburikidza nemagetsi kusvika kumativi kuti ave welded. Panguva imwe chete nekutangira kwechikamu chechikamu chezvino, kupa kweArgon kuburikidza nemushanga unopisa unotanga. Iyo nzira yekupinda munzvimbo yekudonhera yezadza zvinhu, iyo inonyunguduka pasi pechiito chekupisa kwakabudiswa kubva panguva ino inoyerera, inotangwa.

Sezvo argon midzimu isingabvumi kuitika kweArc, zvakakosha kushandisa chigadzirwa chakakosha chinonzi oscillator. Izvi zvinogadzirisa kuvimbika kweArc ne-high-frequency pulses, uye kunowedzera kugadziriswa kwekubudiswa kweArc panguva yekudengenyeka kwepfungwa.

Kubatsira kwekushongedza argon arc nde:

1. Kubudirira.
2. Uwandu hudiki hwomukati welded.
3. Mukana wekutengesa zvikamu pasina kubatanidzwa kwekuzadza zvinhu.
