Kumatshini wokuwelda indawo yokugcina amandla, ukuqinisekisa umgangatho kunye nokuthembeka kwamalungu e-weld kubaluleke kakhulu. Ukufezekisa oku, iindlela ezahlukeneyo zokuhlola zisetyenziselwa ukuvavanya amalungu e-weld kwiziphene, njengokungadibanisi ngokwaneleyo, ukuqhekeka, okanye i-porosity. Eli nqaku liphonononga iindlela ezahlukeneyo zokuhlola i-weld joints kwindawo yokugcina amandla koomatshini be-welding, ukubonelela abaqhubi ngezixhobo ezixabisekileyo zokugcina ii-welds eziphezulu.
- Ukuhlolwa okubonakalayo: Ukuhlola okubonwayo yeyona ndlela isisiseko kwaye isetyenziswa ngokuqhelekileyo yokuvavanya i-weld joints. Abaqhubi bajonga ngokubonakalayo indawo ye-weld kuzo naziphi na iziphene ezibonakalayo, ezinje ngokudityaniswa okungaphelelanga, izitenxo zomphezulu, okanye ukungaqhubeki. Le ndlela idinga iliso eliqeqeshiweyo kunye neemeko ezifanelekileyo zokukhanyisa ukuchonga ngokuchanekileyo imiba enokubakho.
- IiNdlela zokuSebenza zoVavanyo olungonakalisi (NDT): a. Uvavanyo lwe-Ultrasonic: Uvavanyo lwe-Ultrasonic lusebenzisa amaza omsindo aphezulu-ukukhangela iimpazamo zangaphakathi okanye iziphene kumalungu e-weld. Amaza e-Ultrasonic ahanjiswa nge-weld joint, kwaye amaza abonakalisiweyo ahlalutywa ukuchonga nakuphi na ukungaqhelekanga. Obu buchule busebenza ngokukodwa ekubhaqeni iintanda ezingaphantsi komhlaba okanye iporosity.
b. Uvavanyo lweRadiographic: Uvavanyo lweRadiographic lubandakanya ukugqithisa i-X-reyi okanye imitha ye-gamma kwijoyinti ye-weld kunye nokuthatha umfanekiso kwifilimu okanye kwisixhobo sedijithali. Le ndlela inokutyhila iziphene zangaphakathi, ezifana nokungena okungaphelelanga okanye i-voids. Uvavanyo lweRadiographic luluncedo ngakumbi kumalungu ashinyeneyo okanye antsonkothileyo.
c. Uvavanyo lweMagnetic Particle: Uvavanyo lwemagnethi lusetyenziselwa ukuhlola imathiriyeli yeferromagnetic. Intsimi yamagnetic isetyenziswe kwi-weld joint, kwaye iinqununu zamagnetic zisetyenziselwa phezulu. Naziphi na iziphene eziqhekeza phezulu ziya kubangela ukuba iinqununu zemagneti zidibanise, zibonise ubukho besiphako.
d. Uvavanyo lwe-Dye Penetrant: Uvavanyo lokungena kwedayi lusetyenziselwa ukufumanisa iziphene zomhlaba kumalungu e-weld. Idayi enemibala isetyenziswe kumphezulu, kwaye emva kwexesha elithile, idayi engaphezulu iyasuswa. Umphuhlisi uyasetyenziswa, nto leyo itsala idayi ebanjiweyo kuzo naziphi na iziphene, izenze zibonakale.
- Uvavanyo olutshabalalisayo: Kwiimeko ezithile, uvavanyo olutshabalalisayo luyimfuneko ukuvavanya umgangatho we-weld joint. Oku kubandakanya ukususa icandelo lesampulu ye-weld joint kwaye ifakwe kwiimvavanyo ezahlukeneyo, ezifana novavanyo lwe-tensile, ukugoba, okanye uvavanyo lokuqina. Uvavanyo olutshabalalisayo lubonelela ngolwazi oluthe kratya malunga neempawu zemishini ye-weld joint kwaye inokutyhila iziphene ezifihlakeleyo.
Ukuhlola ii-weld joints kwindawo yokugcina amandla koomatshini bokuwelda kubalulekile ekuqinisekiseni umgangatho we-weld kunye nokuthembeka kwesakhiwo. Ngokusebenzisa uhlolo olubonakalayo, iindlela zovavanyo ezingonakalisi (ezifana novavanyo lwe-ultrasonic, uvavanyo lwe-radiographic, uvavanyo lwemagnethi yamagnetic, kunye novavanyo lokungena kwedayi), kwaye, xa kuyimfuneko, uvavanyo olonakalisayo, abaqhubi banokuvavanya ngokufanelekileyo amalunga e-weld kwiziphene. Ukuphumeza inkqubo yokuhlola ebanzi inceda ukugcina imigangatho ephezulu yomgangatho kunye nokuthembeka kwizicelo ze-welding indawo yokugcina amandla. Ukuhlolwa rhoqo kwenza ukuba kuchongwe ngokukhawuleza kwaye kusonjululwe nayiphi na imiba, ekhokelela kumgangatho ophuculweyo we-weld kunye nokusebenza ngokubanzi kwe-welding.
