Kwixesha lobuchwepheshe obuphambili, iinkqubo zoshishino ziye zasebenza kakuhle kwaye zichanekile. Enye yezo nkqubela phambili kukusetyenziswa kweerobhothi zokuwelda nge-laser kwimisebenzi yokuvelisa. Ezi robhothi zibonelela ngee-welds ezikumgangatho ophezulu nezichanekileyo, ziqinisekisa ukuqina kunye nokuthembeka kwemveliso yokugqibela. Nangona kunjalo, ukuqinisekisa umgangatho wokuwelda ohambelanayo nothembekileyo, kufuneka kusetyenziswe iindlela ezininzi ukujonga umgangatho wokuwelda kweerobhothi zokuwelda nge-laser. Kweli nqaku, siza kuhlola iindlela ezahlukeneyo zokujonga umgangatho wee-welds zerobhothi zokuwelda nge-laser.
Ngaphambi kokuba uqale ukwazisa ezi ndlela, kubalulekile ukuqonda ukuba iiparameter ze-welding zeirobhothi yokuwelda nge-laserkufuneka ilungiswe ngokomgangatho wokuwelda. Olu hlengahlengiso luqinisekisa ukuba irobhothi inika iziphumo ezilungileyo ngexesha lokuveliswa kokuwelda ngobuninzi. Kufuneka kugxininiswe ekulinganiseni nasekulungiseni umatshini ukuze kufezekiswe umgangatho wokuwelda ofunekayo rhoqo.
Enye yeendlela ezisetyenziswa kakhulu ukujonga umgangatho wokuwelda kweerobhothi zokuwelda nge-laser kukufumanisa iziphene nge-radiographic. Le ndlela ibandakanya ukusetyenziswa kwe-X- kunye ne-Y-reyi ukuthumela imitha nge-weld. Iziphene ezikhoyo kwi-weld emva koko ziboniswa kwifilimu ye-radiographic, okuvumela umqhubi ukuba abone naziphi na iziphene. Ngokusebenzisa le ndlela, umgangatho we-weld unokuvavanywa ngokupheleleyo ukuqinisekisa ukuba akukho ziphene ezifihlakeleyo ezinokubeka emngciphekweni ukuthembeka kwe-weld.
Ukongeza ekufumaneni iziphene ze-radiographic, enye indlela yokujonga umgangatho wokuweldaiirobhothi zokuwelda nge-laserkukufumanisa iziphene ze-ultrasonic. Le ndlela isebenzisa ukungcangcazela okushukumayo okuveliswa kukuvuseleleka kombane ngoko nangoko. I-arhente yokudibanisa isetyenziswa kumphezulu we-weld ukwenza amaza e-ultrasonic akheke kwisinyithi. Xa la maza edibana neziphene, akhupha imiqondiso ebonakalisiweyo enokuhlaziywa ukuze kuchongwe naziphi na iziphene ezikhoyo kwi-weld. Le ndlela ilandela imigaqo efanayo novavanyo lwe-ultrasound kumaziko ezonyango, ukuqinisekisa iziphumo ezithembekileyo nezichanekileyo.
Ukuchonga iziphene zemagnethi kukwayindlela ebalulekileyo yokujonga umgangatho wokuweldaiirobhothi zokuwelda nge-laserLe ndlela ibandakanya ukufaka umgubo wemagnethi kumphezulu we-weld. Xa kukho iziphene, izinto zemagnethi ziyasabela, nto leyo ebangela ukuba kuvele amasimi okuvuza. Ngokuhlalutya i-magnetic field, umqhubi unokufumanisa ukuba kukho isiphene se-weld. Le ndlela iluncedo ngokukodwa ekuchongeni iziphene zomphezulu nokuqinisekisa ukuba umgangatho we-weld uhlangabezana nemigangatho efunekayo.
Ukongeza kwezi ndlela zintathu zisetyenziswa rhoqo, kukho ezinye iindlela ezinokusetyenziswa ukujonga umgangatho wokuweldaiirobhothi zokuwelda nge-laserOku kuquka ukuhlolwa ngokubona, uvavanyo lokungena kolwelo kunye novavanyo lwamandla e-eddy. Ukuhlolwa ngokubona kubandakanya ukuvavanywa ngokucokisekileyo kwe-weld ngeliso lenyama okanye ngoncedo lwesixhobo sokukhulisa. Uvavanyo lokungena kolwelo, kwelinye icala, lusebenzisa i-liquid penetrant ukungena kwiziphene zomphezulu, ukuze zibonakale phantsi kokukhanya kwe-ultraviolet. Uvavanyo lwamandla e-Eddy lusebenzisa i-electromagnetic induction ukuchonga iziphene zomphezulu kunye nezomphezulu ngokulinganisa utshintsho kwi-electrical conductivity.
Zonke ezi ndlela zidlala indima ebalulekileyo ekuqinisekiseni umgangatho wokuwelda kweerobhothi zokuwelda nge-laser. Ngokusebenzisa ezi teknoloji, abavelisi banokuchonga ngokukhawuleza naziphi na iziphene okanye iziphene zokuwelda baze bathathe amanyathelo afunekayo ukuzilungisa. Oku kukhokelela kumgangatho ophezulu wemveliso kunye nolwaneliseko lwabathengi.
Ngamafutshane, ukujonga umgangatho wokuwelda weirobhothi yokuwelda nge-laserKubalulekile ukuqinisekisa ukuthembeka nokuqina kwemveliso yokugqibela. Iindlela ezahlukeneyo ezifana novavanyo lwe-radiographic, i-ultrasonic kunye ne-magnetic zinokubonelela ngengqiqo ebalulekileyo ngomgangatho we-weld. Abavelisi kufuneka badibanise ezi ndlela kwiinkqubo zabo zokulawula umgangatho ukuze bagcine imigangatho ephezulu yomgangatho we-weld. Ngokwenza njalo, banokuzisa iimveliso ezihlangabezana okanye ezidlula ulindelo lwabathengi kwaye bakhe udumo lokugqwesa kushishino.
