Umbhobho weSpiral welding (umbhobho we-SSAW)luhlobo lombhobho wentsimbi yomthungo ojikelezayo owenziwe nge-coil yentsimbi njengento ekrwada, edityaniswe yinkqubo yokuwelda i-arc ezenzekelayo enamacala amabini kwaye ikhutshwe kwiqondo lobushushu legumbi. Ubunjineli bokubonelela ngamanzi, ishishini lepetrochemical, ishishini lemichiza, ishishini lamandla ombane, ukunkcenkceshela kwezolimo kunye nolwakhiwo lwasezidolophini ngamasimi apho i-spiralimibhobho edityanisiweyozisetyenziswa ikakhulu.

Iimpawu eziphambili zenkqubo yombhobho we-spiral welded:

1. Ngethuba lenkqubo yokubumba, uxinzelelo olushiyekileyo luncinci kwaye akukho mkrwelo phezu komhlaba. Umbhobho we-spiral welding owenziweyo uneenzuzo ezingenakuthelekiswa nanto kubungakanani kunye noluhlu oluchaziweyo lwedayamitha kunye nobukhulu bodonga, kwaye unokuhlangabezana neemfuno ezininzi zabasebenzisi kwiinkcukacha zemibhobho yentsimbi ejikelezayo.
2. Yamkela itekhnoloji yokuwelda ye-arc ekwicala eliphindwe kabini ukujongana neziphene ezithile, kwaye kulula ukulawula umgangatho we-welding.
3. Ukuhlola umgangatho we-100% kwipayipi yensimbi, ukwenzela ukuba uqinisekise umgangatho wemveliso.

4. Zonke izixhobo kuwo wonke umgca wokuvelisa unomsebenzi wokunxibelelana kunye nenkqubo yokufumana idatha yekhompyutheni ukuqonda ukuhanjiswa kwedatha yexesha langempela, kwaye iiparitha zobugcisa kwinkqubo yokuvelisa zilawulwa yigumbi lokulawula.

Ukulungiselela inkqubo yokufudumeza, izixhobo zokufudumeza unyango lokushisa kunye ne-heater medium kufuneka zikhethwe. Kwenzeka ntoni okanye kulula ukwenzeka apha kukuba umphezulu wenxalenye uya kuchaphazeleka yi-oxidizing medium heat, kwaye ubushushu bokufudumala budlula iimfuno zenkqubo. Ukuba iinkozo ze-austenite zinzima kakhulu, kunye nemida yengqolowa iya kunyibilika, eya kuchaphazela kakhulu ukubonakala kunye nomgangatho wangaphakathi wamacandelo. Ngoko ke, kwinkqubo eyiyo, amanyathelo anokwenzeka kufuneka athathwe ukuhlalutya ezo ziphene.

Amalungu anesiphene avelisiweyo ngexesha lokufudumala acinywa ukufumana isakhiwo se-martensite esicinyiweyo esinobunzima obuphezulu okanye isakhiwo esisezantsi se-bainite enobunzima obuncinci, kodwa isakhiwo asizinzile kwaye sinobunzima. Xa isetyenziswe kwimveliso, iyancipha ukufumana isakhiwo esifunwayo kunye neempawu. Ke ngoko, iiparamitha zenkqubo yobushushu ziya kuba nefuthe elibalulekileyo kumgangatho wonyango lobushushu lwamalungu, njengokuqina, ukuqina, ukuqhekeka kweentanda kunye nezinye iziphene, kwaye amanyathelo kufuneka athathwe ukuphepha ezi ziphene ngexesha lobushushu.

Inkqubo echanekileyo yonyango lobushushu yisiseko kunye nesiseko sokuqinisekisa umgangatho wonyango olufanelekileyo lwamalungu. Emva kokuba iingxaki zomgangatho ongentla zifunyenwe, zinokusombululwa kwiinkalo zabantu, oomatshini, izixhobo, iindlela, amakhonkco, ukuhlolwa, njl. Ngokuhlalutya kunye nesigwebo, ingcambu yengxaki inokufumaneka.

Izakhono zokugcina umbhobho we-spiral welded:

1. Indawo yokugcina okanye indawo yokugcina iimveliso zemibhobho yensimbi ejikelezayo kufuneka ibekwe kwindawo ecocekileyo neyomileyo. Ukhula kunye nazo zonke iindidi kufuneka zicocwe. Imivalo yentsimbi kufuneka igcinwe icocekile kwaye ikude nemizi-mveliso kunye nemigodi evelisa iigesi eziyingozi okanye uthuli.
2. Izinto ezonakalisa intsimbi ezifana ne-asidi, i-alkali, ityuwa, nesamente aziyi kubekwa kwindawo yokugcina impahla, kwaye intsimbi yeentlobo ezahlukeneyo iya kupakishwa ngokwahlukeneyo. Thintela ukubhideka kunye nomhlwa.
3. Intsimbi yecandelo elincinci kunye neliphakathi, intonga yocingo, intsimbi yentsimbi, umbhobho wensimbi ophakathi kobubanzi, intambo yensimbi kunye nentambo yocingo, njl. Emva kokubeka kunye ne-cushioning, inokugcinwa kwi-shed epholileyo.

4. Intsimbi encinci, ipleyiti yentsimbi ebhityileyo, umcu wentsimbi, ishidi lentsimbi yesilicon okanye umbhobho wentsimbi obhityileyo obhityileyo unokugcinwa. Iintlobo ngeentlobo zexabiso eliphezulu, ezonakalisayo ezibandayo eziqengqelekayo kunye neemveliso zentsimbi ezitsalwa ngokubanda kunye neentsimbi zinokugcinwa.
