I-Adiabatic Welding iyindlela edumile esetshenziswa ezinhlobonhlobo zezimboni lapho kudingeka khona ukujoyina izinsimbi okunembile. Kodwa-ke, enye yezinselelo eziphambili kule nqubo isizukulwane sokushisa ngokweqile, okungathinta ubuqotho bokuhlanganiswa kwe-welded. Ukuxazulula le nkinga, ukupholisa i-adiabatic weverwetic ye-adiabatic kuqhamuke njengesixazululo esithembekile. Kulesi sihloko, sixoxa ngezici nezinzuzo zale ndlela yokupholisa futhi sihlole imikhiqizo esebenza ukusebenza kwayo.
Ukupholisa okusheshayo futhi okulula kwe-adiabatic weld kunciphisa kakhulu isikhathi esipholile esidingekayo endaweni ebekiwe. Ukushisa okwedlulele okwenziwe ngesikhathi senqubo ye-welding kudilizwa ngokushesha ngokusebenzisa ubuchwepheshe obukhethekile bokupholisa, ukuqinisekisa ubuqotho namandla e-welded Joint. Le ndlela yokupholisa inikeza izinzuzo eziningana ezifana nokukhiqiza okwengeziwe, incishiswe ukukhiqizwa kwe-post-weld, kuthuthukiswe ngekhwalithi ephelele yenqubo ye-welding, kanye nokuphepha kwe-welder okwengeziwe.
Umkhiqizo owodwa osiza ukupholisa okusheshayo futhi okulula kwe-adiabatic welding yi-welding insud gar cylinder. Isilinda sisebenzisa umklamo wesakhiwo ongezandelayo ophindwe kabili, ohlanganiswa ithangi elingaphakathi nethangi elingaphandle, futhi unongqimba lokufakelwa kokushisa. Kusetshenziswa izinto zokuvimbela ukushisa ezinobuningi ukuze kugcinwe i-vacuum ephezulu, kusetshenziselwa ukuthutha kanye nokugcinwa komoya-mpilo, i-nitrogen ewuketshezi, i-argon ye-liquid kanye nezinye iziphuzo.
Ama-cylinder we-welding efaka ama-cylinder atholakala kumamodeli ahlukene ukuze ahlangabezane nezidingo ezihlukile zohlelo lokusebenza. Ngokusho kwengcindezi esethiwe ye-valve yezokuphepha, ihlukaniswe ngengcindezi ephakathi (MP) kanye nengcindezi ephezulu (p). Ngaphezu kwalokho, kunengcindezi ephezulu kakhulu (i-Vep) ehlukile, evame ukusetshenziselwa izinhlelo zokusebenza ezibandakanya izingcindezi eziphakathi neziphezulu. Le assortment iqinisekisa ukuthi ama-cylinders angahambisa kahle womabili amagesi awuketshezi kanye nama-gaseous wezidingo ezihlukile ze-welding.
Kunezinzuzo eziningi zokusebenzisa amasilinda egesi afakwe e-Welded efaka. Ukwakhiwa kwalo okunezinhlamvu ezimbili nokufakwa kwe-thermal kusiza ukugcina izinga lokushisa likagesi ogciniwe, ukuvimbela noma yiziphi izinguquko ezingathandeki ezingathinta inqubo ye-welding. I-vacuum ephezulu egcinwe ngaphakathi kwesilinda iqhubeka nokuqinisekisa ubumsulwa nokuqina koketshezi olugciniwe, okuholela ekusebenzeni okuthembekile nokungaguquki.
Ngaphezu kwalokho, ukupholisa okusheshayo futhi okulula okutholakale ngalo mkhiqizo kunciphisa kakhulu phakathi kwemisebenzi ye-welding. Ngokushisa ngokweqile okuhlanjululwe ngokushesha, ama-welders angadlulela ngokushesha endaweni elandelayo, akhuphuke umkhiqizo ophelele. Isikhathi sokupholisa esincishisiwe siphinde sinciphise ukuhlanekezela kwe-post-weld ngemiphumela eqondile yokufafaza. Ngokwengeziwe, le ndlela yokupholisa inciphisa ukuvezwa kweWelder ekushiseni okwedlulele, okwandayo kwe-Welder Safety.
Ekuphetheni, ukupholisa okusheshayo futhi okulula kwama-adiabatic welds kubalulekile ukufeza ama-welds asezingeni eliphakeme ngaphandle kokuyekethisa ubuqotho namandla ahlanganyelwe. Ama-cylinder we-welded afakwe igesi yimikhiqizo efinyelela le ndlela yokupholisa ngokwakha okuphezulu, ukufakwa kokushisa, kanye nokulungiswa kwe-vacuum ephezulu. Amandla alo okugcina nokuhambisa zombili iziphuzo eziwuketshezi kanye namagesi ashukumisayo kwenza kufanelekile ukuthola izinhlelo ezahlukahlukene zokufaka. Ukusebenzisa amasu wokupholisa asheshayo, alula akugcini nje ngokukhulisa umkhiqizo, kepha futhi kuthuthukisa imiphumela yokushiswa futhi uqinisekise ukuphepha kwe-Welder.
