Kwindawo yokuvelisa kunye nokwenziwa, ukuthembeka koomatshini be-welding welding eyona nto ibalulekileyo. Aba matshini badlala indima ebaluleke kakhulu ekudibaniseni isinyithi kunye, beqinisekisa intembeko yolwakhiwo lweemveliso ezininzi esidibana nazo kubomi bethu bemihla ngemihla. Ukuqinisekisa umgangatho weewelds zeendawo kunye nokugcina ukusebenza kakuhle kwaba matshini, iindlela zokuhlola ezingonakalisi ziyimfuneko.
Intshayelelo
I-Resistance spot welding, ubuchule obusetyenziswa ngokubanzi kwimizi-mveliso yeemoto, i-aerospace, kunye nolwakhiwo, ibandakanya ukudityaniswa kweentsimbi ezimbini ngokusetyenziswa kobushushu kunye noxinzelelo. Umgangatho wezi welds ubalulekile, njengoko zimisela ukuqina kunye nokhuseleko lwemveliso yokugqibela. Iindlela zokuhlola ezingonakalisi (NDI) ziye zavela njengesixhobo esibalulekileyo ekuhloleni ingqibelelo ye-welds spot ngaphandle kokubangela umonakalo kwizinto ezidibeneyo.
Uvavanyo lweUltrasonic (UT)
Enye yeendlela ezixhaphakileyo ze-NDI zokumelana noomatshini bokuwelda kuvavanyo lwe-ultrasonic (UT). I-UT isebenzisa amaza omsindo aphezulu athunyelwa nge-weld joint. La maza abuyela umva xa edibana nezitenxo ezinje ngee-voids okanye iintanda ngaphakathi kweweld. Ngokuhlalutya ixesha elithathayo ukuze ezi echoes zibuye kunye nobukhulu bazo, abahloli banokuchonga iziphene ezinokuthi zibe kho.
Uvavanyo lweRadiographic (RT)
Uvavanyo lweRadiographic bobunye ubuchule be-NDI obunamandla. Kule ndlela, i-X-rays okanye i-gamma ray iqondiswe kwi-weld. Umfanekiso weradiographic uye uveliswa kwifilimu yeefoto okanye kwisixhobo sedijithali. I-Discontinuities kwi-weld, njenge-inclusions okanye i-voids, ibonakala njengezithunzi kwi-radiograph. Amagcisa anezakhono eziphezulu anokutolika le mifanekiso ukuvavanya umgangatho we-weld.
Uvavanyo lwangoku lukaEddy (ECT)
Uvavanyo lwangoku lwe-Eddy luluncedo ngakumbi ekufumaneni iziphene ezikumphezulu kunye nezikufuphi kumphezulu kwiindawo zokuwelda. Isebenza ngokubangela imisinga eddy kwizinto eziqhubayo kunye nokulinganisa utshintsho kwi-conductivity yombane obangelwa ziziphene. I-ECT yindlela ekhawulezayo neguquguqukayo enokuchonga imiba efana nokuqhekeka, i-porosity, kunye nokwahluka kobuninzi bezinto.
Iingenelo zokuHlola okungonakalisi
Iingenelo zokusebenzisa iindlela zokuhlola ezingonakalisiyo kumatshini wokuwelda kwindawo yokumelana ziyabonakala. Ezi ndlela zivumela ukubonwa kwangaphambili kweziphene, ukuthintela ukuveliswa kweemveliso ezingaphantsi okanye ezinokungakhuselekanga. Bakwanciphisa inkunkuma yezinto kwaye bagcine ixesha xa kuthelekiswa novavanyo olutshabalalisayo, apho i-weld ivavanywa ngokwasemzimbeni ukuba ingaphumeleli.
Kwihlabathi lokuvelisa, ukuchaneka kunye nokuthembeka kubaluleke kakhulu. Ukusetyenziswa kweendlela zokuhlola ezingonakalisiyo zokumelana noomatshini bokuwelda baqinisekisa ukuba iimveliso esithembele kuzo zokhuseleko kunye nokusebenza zihlangabezana nemigangatho ephezulu. Ngokusebenzisa ubuchule obunjengovavanyo lwe-ultrasonic, uvavanyo lwe-radiographic, kunye novavanyo lwangoku lwe-eddy, abavelisi banokugcina ingqibelelo yee-welds zabo, baphucule umgangatho wemveliso, kwaye ekugqibeleni, bafumane ukuthenjwa ngabathengi babo.
