Ukuwelda nge-Adiabatic yindlela ethandwayo esetyenziswa kumashishini amaninzi apho kufuneka ukuhlanganiswa kweentsimbi ngokuchanekileyo nangokufanelekileyo. Nangona kunjalo, omnye wemingeni ephambili kule nkqubo kukuveliswa kobushushu obugqithisileyo, obunokuchaphazela ukuthembeka kwejoyinti ewelding. Ukusombulula le ngxaki, ukuphola nge-adiabatic weld okukhawulezayo nokulula kuye kwavela njengesisombululo esithembekileyo. Kweli nqaku, sixoxa ngeempawu kunye neenzuzo zale ndlela yokuphola kwaye sihlolisise iimveliso ezenza kube lula ukuyisebenzisa.
Ukupholisa ngokukhawuleza nangokulula kwe-weld ye-adiabatic kunciphisa kakhulu ixesha lokupholisa elifunekayo kwindawo edibeneyo. Ubushushu obugqithisileyo obuveliswa ngexesha lenkqubo yokudibanisa buphela ngokukhawuleza ngokusebenzisa itekhnoloji yokupholisa ekhethekileyo, ukuqinisekisa ukuthembeka kunye namandla ejoyinti edibeneyo. Le ndlela yokupholisa inika iingenelo ezininzi ezifana nokwanda kwemveliso, ukunciphisa ukugqwetheka emva kokudibanisa, ukuphucula umgangatho wenkqubo yokudibanisa, kunye nokhuseleko oluphezulu lwe-welder.
Enye imveliso eyenza kube lula ukupholisa ngokukhawuleza nangokulula kwi-adiabatic welding yiWelding Insulated Gas Cylinders. Isilinda isebenzisa uyilo lwesakhiwo esineengqimba ezimbini, esenziwe ngetanki yangaphakathi kunye netanki yangaphandle, kwaye inomaleko wokukhusela ubushushu. Isebenzisa izixhobo zokukhusela ubushushu ezineengqimba ezininzi ukugcina i-vacuum ephezulu, isetyenziselwa ukuthutha nokugcina ioksijini, i-nitrogen engamanzi, i-argon engamanzi kunye nezinye izinto ezingamanzi.
Iisilinda zegesi ezikhusela ukuwelda ziyafumaneka kwiimodeli ezahlukeneyo ukuhlangabezana neemfuno ezahlukeneyo zokusetyenziswa. Ngokwengcinezelo esetiweyo yevalvu yokhuseleko, yahlulwe yaba luxinzelelo oluphakathi (MP) kunye noxinzelelo oluphezulu (P). Ukongeza, kukho uhlobo loxinzelelo oluphezulu kakhulu (VEP), oluhlala lusetyenziswa kwizicelo ezibandakanya uxinzelelo oluphakathi noluphezulu. Olu luhlu luqinisekisa ukuba iisilinda zinokubonelela ngokufanelekileyo ngeegesi zolwelo kunye nezegesi kwiimfuno ezahlukeneyo zokwelda.
Kukho iingenelo ezininzi zokusebenzisa ii-welded insulating gas cylinders. Ukwakhiwa kwayo okuphindwe kabini okune-thermal insulation kunceda ukugcina ubushushu begesi egciniweyo, kuthintela naluphi na utshintsho olungafunekiyo olunokuchaphazela inkqubo yokudibanisa. I-vacuum ephezulu egcinwe ngaphakathi kwi-cylinder iqinisekisa ngakumbi ubunyulu kunye nokuzinza kolwelo olugciniweyo, okubangela imisebenzi yokudibanisa ethembekileyo neqhubekayo.
Ukongeza, ukupholisa okukhawulezayo nokulula okufezekiswa yile mveliso kunciphisa kakhulu ixesha lokungasebenzi phakathi kwemisebenzi yokuwelda. Xa ubushushu obugqithisileyo buphela ngokukhawuleza, abawelda banokuhamba ngokukhawuleza baye kwindawo elandelayo, benyusa imveliso iyonke. Ixesha lokupholisa elinciphileyo likwanciphisa ukugqwetheka emva kokuwelda ukuze kufunyanwe iziphumo ezichanekileyo zokuwelda. Ukongeza, le ndlela yokupholisa inciphisa ukuvezwa komwelda kubushushu obugqithisileyo, nto leyo eyandisa ukhuseleko lomwelda.
Ukuqukumbela, ukupholisa ngokukhawuleza nangokulula kwee-welds ze-adiabatic kubalulekile ukuze kufunyanwe ii-welds ezikumgangatho ophezulu ngaphandle kokuphazamisa ukuthembeka kunye namandla adibeneyo. Ii-cylinders zegesi ezifakwe i-insulation ezihlanganisiweyo ziimveliso ezifezekisa le ndlela yokupholisa ngokwakhiwa kwee-double layers, i-heat insulation, kunye nokugcinwa kwe-vacuum ephezulu. Amandla ayo okugcina nokuthutha iigesi zolwelo kunye neegesi kuyenza ifaneleke kwiintlobo ngeentlobo zezicelo ze-welding. Ukusebenzisa iindlela zokupholisa ezikhawulezayo nezilula akunyusi nje kuphela imveliso, kodwa kuphucula iziphumo ze-welding iyonke kwaye kuqinisekisa ukhuseleko lwabafake i-welding.
