I-Adiabatic welding iyindlela edumile esetshenziswa ezimbonini eziningi lapho kudingeka khona ukuhlanganisa okunembe, okuphumelelayo kwezinsimbi. Kodwa-ke, enye yezinselele eziyinhloko kule nqubo isizukulwane sokushisa ngokweqile, okungathinta ubuqotho bokuhlanganiswa okuhlanganisiwe. Ukuxazulula le nkinga, ukupholisa kwe-adiabatic weld okusheshayo nokulula kuye kwavela njengesixazululo esithembekile. Kulesi sihloko, sixoxa ngezici nezinzuzo zale ndlela yokupholisa futhi sihlole imikhiqizo eyenza ukuqaliswa kwayo kube lula.
Ukupholisa okusheshayo nokulula kwe-adiabatic weld kunciphisa kakhulu isikhathi sokupholisa esidingekayo endaweni eshiselwe. Ukushisa okweqile okukhiqizwa phakathi nenqubo yokushisela kushabalaliswa ngokushesha ngokusebenzisa ubuchwepheshe bokupholisa obukhethekile, okuqinisekisa ubuqotho namandla okuhlangana okushiselwe. Le ndlela yokupholisa inikeza izinzuzo eziningana ezifana nokwanda kokukhiqiza, ukunciphisa ukuhlanekezela ngemuva kokushisela, ikhwalithi ethuthukisiwe yenqubo yokushisela, kanye nokwenyuka kokuphepha kokushisela.
Omunye umkhiqizo osiza ukupholisa okusheshayo nokulula kokushisela i-adiabatic i-Welding Insulated Gas Cylinders. Isilinda sithatha idizayini yesakhiwo esinezendlalelo ezimbili, esakhiwe ithangi langaphakathi nethangi langaphandle, futhi linongqimba oluvala ukushisa. Ukusebenzisa izinto zokufaka ukushisa okunezingqimba eziningi ukuze kugcinwe i-vacuum ephezulu, isetshenziselwa ukuthutha nokugcina umoya-mpilo, i-nitrogen eyi-liquid, i-argon ye-liquid kanye nolunye uketshezi.
Amasilinda e-welding insulating gas ayatholakala kumamodeli ahlukene ukuze ahlangabezane nezidingo ezahlukene zohlelo. Ngokwengcindezi ebekiwe ye-valve yokuphepha, ihlukaniswe ngokucindezela okuphakathi (MP) nokucindezela okuphezulu (P). Ukwengeza, kunokwehluka kwengcindezi ephezulu kakhulu (VEP), evame ukusetshenziselwa izinhlelo zokusebenza ezibandakanya izingcindezi eziphakathi nendawo neziphezulu. Le assortment iqinisekisa ukuthi amasilinda angakwazi ukuhlinzeka ngokuyikho kokubili amagesi awuketshezi negesi ngezidingo ezahlukene zokushisela.
Kunezinzuzo eziningi zokusebenzisa amasilinda egesi afaka insulating ashiselwe. Ukwakhiwa kwayo kwe-double-layer nge-thermal insulation kusiza ukugcina izinga lokushisa kwegesi egciniwe, ukuvimbela noma yiziphi izinguquko ezingathandeki ezingase zithinte inqubo yokushisela. I-vacuum ephezulu egcinwe ngaphakathi kwesilinda iqinisekisa ngokwengeziwe ukuhlanzeka nokuzinza koketshezi olugciniwe, okuholela ekusebenzeni okuthembekile nokungaguquguquki kokushisela.
Ngaphezu kwalokho, ukupholisa okusheshayo nokulula okutholwe yilo mkhiqizo kunciphisa kakhulu isikhathi sokuphumula phakathi kokusebenza kwe-welding. Ngokushisa okweqile kuqedwe ngokushesha, ama-welders angadlulela ngokushesha endaweni elandelayo, okwandisa umkhiqizo jikelele. Isikhathi sokupholisa esincishisiwe siphinde sinciphise ukuhlanekezela kwangemuva kokushisela ukuze kube nemiphumela enembile yokushisela. Ukwengeza, le ndlela yokupholisa inciphisa ukuchayeka komshiseli ekushiseni okukhulu, okwandisa ukuphepha kwe-welder.
Ekuphetheni, ukupholisa okusheshayo nokulula kwe-adiabatic welds kubalulekile ukuze kuzuzwe izinga eliphezulu lekhwalithi ngaphandle kokuyekethisa ubuqotho obuhlangene namandla. Amasilinda egesi afakwe i-insulated ayimikhiqizo efinyelela le ndlela yokupholisa ngokwakhiwa kwezingqimba ezimbili, ukufakwa kokushisa, nokugcinwa kwe-vacuum ephezulu. Ikhono layo lokugcina nokuthutha kokubili amagesi awuketshezi kanye negesi ayenza ifaneleke ezinhlobonhlobo zezicelo zokushisela. Ukusebenzisa amasu okupholisa asheshayo, alula akukhulisi nje kuphela ukukhiqiza, kodwa futhi kuthuthukisa imiphumela yokushisela yonke futhi kuqinisekisa ukuphepha kwe-welder.
