Yintoni i-Summerged Arc Welding (SAW)?

I-arc welding ephantsi kwamanzi (i-SAW), njengoko igama libonisa, liqhutywa phantsi komgangatho okhuselayo okanye ingubo ye-flux.Njengoko i-arc isoloko igutyungelwe bubunzima be-flux, iphelisa nayiphi na i-radiation evela kwii-arches eziveziweyo kunye nemfuneko yezikrini ze-welding.Ngeenguqu ezimbini zenkqubo, ngokuzenzekelayo kunye ne-semi-automatic, yenye yenkqubo ye-welding esetyenziswa ngokubanzi kwishishini lenkqubo.I-Wenzhou Tianyu Electronic Co., Ltd., omnye wabanikezeli bengcingo bokuwelda be-arc abadumileyo e-China, ibonisa umgaqo kunye nokusetyenziswa kwe-sub-arc welding.Masibabone ukuba bayintoni na:

Inkqubo:

I-Akin kwi-MIG welding, i-SAW isebenzisa ubuchule bokwenza i-arc phakathi kwe-weld joint kunye ne-electrode engapheliyo yocingo.Uluhlu oluncinci lwe-flux kunye ne-slag zisetyenziselwa ukuvelisa imixube yegesi ekhuselekileyo kunye nokongeza i-alloys efunekayo kwi-weld pool, ngokulandelanayo.Njengoko i-weld iqhubeka, ucingo lwe-electrode lukhutshwa ngesantya esifanayo sokusetyenziswa kwaye i-flux engaphezulu ikhutshwe nge-vacuum system yokuphinda isetyenziswe.Ngaphandle kokukhusela i-radiation, i-flux layers iluncedo kakhulu ekuthinteleni ukulahleka kobushushu.Ukusebenza kakuhle kwe-thermal yale nkqubo, malunga ne-60%, kubalelwa kolu luhlu lwe-flux.Kwakhona inkqubo ye-SAW ayinakutshiza ngokupheleleyo kwaye ayifuni nayiphi na inkqubo yokutsalwa komphunga.

Inkqubo yokusebenza:

Njengayo nayiphi na enye inkqubo ye-welding, umgangatho we-weld joints malunga nobunzulu bokungena, imilo kunye nokwakheka kweekhemikhali zentsimbi ye-weld edipozithiweyo idla ngokulawulwa ziiparamitha zokuwelda ezifana nezangoku, i-arc voltage, ireyithi ye-weld wire feed, kunye nesantya sokuhamba se-weld.Enye yeengxaki (ngokuqinisekileyo iindlela zikhoyo zokulwa nazo) kukuba i-welder ayikwazi ukujonga i-weld pool kwaye ngoko umgangatho wequla uxhomekeke ngokupheleleyo kwiiparameters zokusebenza.

Iiparamitha zenkqubo:

Njengoko kukhankanyiwe ngaphambili, kuphela ngeeparamitha zenkqubo, kwaye i-welder ifezekisa i-weld joint.Ngokomzekelo, kwinkqubo ezenzekelayo, ubungakanani bocingo kunye ne-flux esetyenzisiweyo efanelekileyo kuhlobo oluqhelekileyo, ubukhulu bezinto eziphathekayo, kunye nobukhulu bomsebenzi udlala indima ebalulekileyo ekugqibeni izinga lokubekwa kunye neemilo ze-bead.

ucingo:

Ngokuxhomekeke kwimfuno yomlinganiselo wokubekwa kunye nezantya zokuhamba emva kweengcingo zinokukhethwa

·Twin-wire

·Iingcingo ezininzi

·Ucingo lweTubula

·Ukongeza umgubo wesinyithi

·Ngocingo olunye olongeziweyo olushushu

·Ngocingo olunye olongezelelo olubandayo

Flux:

Umxube we-granular we-oxides yezinto ezininzi ezifana ne-manganese, i-titanium, i-calcium, i-magnesium, i-silicon, i-aluminium, kunye ne-calcium fluoride isetyenziswa ngokubanzi njenge-flux kwi-SAW.Ngokuqhelekileyo, ukudibanisa kukhethwe ngendlela yokuba ibonelele ngeempawu ezijoliswe kuyo xa idibanisa kunye nocingo lwe-welding.Kufuneka kwakhona kuqatshelwe ukuba ukubunjwa kwezi mpukane kudlala indima ebalulekileyo kwi-voltage ye-arc yokusebenza kunye neeparitha zangoku.Ngokusekwe kwimfuno ye-welding, ngokuyintloko iintlobo ezimbini ze-fluxes, ezidibeneyo kunye ne-fused ziqeshwe kwinkqubo.

Usebenzisa:

Yonke indlela ye-welding inesethi yayo yezicelo, ezidla ngokugqithwa ngenxa yobungakanani boqoqosho kunye nemfuno yomgangatho.

Nangona i-SAW inokuqashwa kakuhle kakhulu kuzo zombini iindawo zempundu (i-longitudinal kunye ne-circumferential) kunye ne-fillet joints, inezithintelo ezincinci ezimbalwa.Ngenxa yobuninzi bechibi le-weld pool, i-slag kwindawo etyhidiweyo kunye nomaleko okhululekileyo we-flux, i-butt joints zihlala ziqhutyelwa kwindawo ethe tyaba, kwaye kwelinye icala, i-fillet joints yenziwa kuzo zonke izikhundla - flat, horizontal, kwaye nkqo.

Kufuneka kuqatshelwe ukuba ngokude nje iinkqubo ezifanelekileyo kunye nokukhethwa kweeparameters zamalungiselelo adibeneyo, i-SAW inokuqhutyelwa ngempumelelo kwizinto eziphathekayo naluphi na ubukhulu.

Inokuthi ibekwe kakuhle kwiintsimbi zekhabhoni, iintsimbi ezingenasici kunye neentsimbi ezisezantsi zealloy kunye neealloyi ezimbalwa ezingenayo i-ferrous kunye nemathiriyeli, ngaphandle kokuba ikhowudi ye-ASME ecetyisiweyo indibaniselwano yocingo kunye ne-flux iyasetyenziswa.

I-SAW ifumana indawo esisigxina kumashishini omatshini onzima kunye namashishini okwakha iinqanawa kumacandelo amakhulu e-welding, imibhobho emikhulu yobukhulu, kunye neenqanawa zenkqubo.

Ngokusetyenziswa okuphezulu kakhulu kocingo lwe-electrode kunye nokufikeleleka kwe-automation mathuba, i-SAW ihlala yenye yezona nkqubo zifunwa kakhulu emva kwe-welding kushishino lokuvelisa.
