Incazelo ye-Splash Defect: I-Splash ekushiseni ibhekisela kumaconsi ensimbi ancibilikisiwe akhishwa echibini elincibilikisiwe ngesikhathi senqubo yokushiseni. La maconsi angawela endaweni yokusebenza ezungezile, okubangela ukugoba nokungalingani ebusweni, futhi angabangela nokulahlekelwa yikhwalithi yechibi elincibilikisiwe, okuholela ekuqhekekeni, amaphuzu okuqhuma, kanye nezinye izinkinga ebusweni bokushiseni ezithinta izakhiwo zemishini ze-weld.
I-Splash in welding ibhekisela kumaconsi ensimbi ancibilikisiwe akhishwa echibini elincibilikisiwe ngesikhathi senqubo yokushisela. La maconsi angawela endaweni yokusebenza ezungezile, okubangela ukugoba nokungalingani ebusweni, futhi angabangela nokulahlekelwa yikhwalithi yechibi elincibilikisiwe, okuholela ekuqhekekeni, amaphuzu okuqhuma, kanye nezinye izinkinga ebusweni bokushisela ezithinta izakhiwo zemishini ze-weld.
Ukuhlukaniswa kwe-Splash:
Ukuchaphaza okuncane: Amaconsi okuqina akhona emaphethelweni omthungo wokushisela kanye naphezu kwezinto zokwakha, ikakhulukazi athinta ukubukeka futhi angabi nomthelela ekusebenzeni; Ngokuvamile, umkhawulo wokuhlukanisa ukuthi ithonsi lingaphansi kuka-20% wobubanzi bokuhlanganiswa komthungo wokushisela;
Ukuchitheka okukhulu: Kukhona ukulahleka kwekhwalithi, okubonakaliswa njengokuqhekeka, amaphuzu okuqhuma, ukunqunywa okungaphansi, njll. ebusweni bomthungo wokushisela, okungaholela ekucindezelekeni okungalingani kanye nokucindezeleka, okuthinta ukusebenza komthungo wokushisela. Ukugxila okuyinhloko kulezo zinhlobo zamaphutha.
Inqubo yokwenzeka kwe-Splash:
I-Splash ibonakala njengokujova kwensimbi encibilikisiwe echibini elincibilikisiwe ngendlela ecishe iqonde ngqo ebusweni boketshezi lokushisela ngenxa yokusheshisa okuphezulu. Lokhu kungabonakala ngokucacile esithombeni esingezansi, lapho ikholomu yoketshezi iphakama khona kusukela ekuncibilikeni kwe-welding bese ibola ibe amaconsi, yakha ama-splashes.
Isigcawu sesehlakalo se-Splash
Ukushisela nge-laser kuhlukaniswe ngokushisa kanye nokushisela kokungena okujulile.
Ukushisela ugesi osebenzisa ukushisa cishe akukho okwenzekayo kokushisela: Ukushisela ugesi osebenzisa ukushisa ikakhulukazi kuhilela ukudluliselwa kokushisa kusuka ebusweni bezinto kuya ngaphakathi, cishe kungekho kushisela okukhiqizwayo phakathi nenqubo. Le nqubo ayihileli ukuhwamuka okukhulu kwensimbi noma ukusabela komzimba kwensimbi.
Ukushisela okujulile kuyisimo esiyinhloko lapho kwenzeka khona ukuchaphaza: Ukushisela okujulile kuhilela ukufinyelela ngqo ezintweni nge-laser, ukudlulisela ukushisa ezintweni ngezimbobo zokhiye, futhi ukusabela kwenqubo kuba kukhulu, okwenza kube yisimo esiyinhloko lapho kwenzeka khona ukuchaphaza.
Njengoba kuboniswe esithombeni esingenhla, ezinye izazi zisebenzisa izithombe zesivinini esikhulu ezihlanganiswe nengilazi ekhanyayo eshisa kakhulu ukuze zibone isimo sokunyakaza kwembobo yokhiye ngesikhathi sokushisela nge-laser. Kungatholakala ukuthi i-laser ishaya odongeni lwangaphambili lwembobo yokhiye, isunduza uketshezi ukuthi lugeleze phansi, idlule imbobo yokhiye bese ifinyelela umsila wechibi elincibilikisiwe. Indawo lapho i-laser itholwa khona ngaphakathi kwembobo yokhiye ayizinzile, futhi i-laser isesimweni sokumuncwa kwe-Fresnel ngaphakathi kwembobo yokhiye. Eqinisweni, iyisimo sokumuncwa okuningi nokumuncwa, okugcina ukuba khona koketshezi lwechibi elincibilikisiwe. Indawo yokumuncwa kwe-laser ngesikhathi senqubo ngayinye iyashintsha nge-engeli yodonga lwembobo yokhiye, okwenza imbobo yokhiye ibe sesimweni sokunyakaza okusontekile. Indawo yokushiswa kwe-laser iyancibilika, iphele, iphoqeleke, futhi iguquke, ngakho-ke ukudlidliza kwe-peristaltic kuya phambili.
Ukuqhathanisa okukhulunywe ngakho ngenhla kusebenzisa ingilazi ekhanyayo eshisa kakhulu, empeleni elingana nombono oqondile wechibi elincibilikisiwe. Phela, isimo sokugeleza kwechibi elincibilikisiwe sihlukile esimweni sangempela. Ngakho-ke, ezinye izazi zisebenzise ubuchwepheshe bokuqandisa okusheshayo. Ngesikhathi senqubo yokushisela, ichibi elincibilikisiwe liyaqandiswa ngokushesha ukuze kutholakale isimo esisheshayo ngaphakathi kwembobo yokhiye. Kungabonakala ngokucacile ukuthi i-laser ishaya odongeni lwangaphambili lwembobo yokhiye, yakha isinyathelo. I-laser isebenza kulo msele wesinyathelo, isunduza ichibi elincibilikisiwe ukuthi ligeleze liye phansi, igcwalisa igebe lembobo yokhiye ngesikhathi sokuhamba phambili kwe-laser, futhi ngaleyo ndlela ithole umdwebo wokuqondisa ukugeleza okulinganiselwe kokugeleza ngaphakathi kwembobo yokhiye yechibi langempela elincibilikisiwe. Njengoba kuboniswe esithombeni esifanele, ingcindezi yokubuyela emuva kwensimbi ekhiqizwa yi-laser ablation yensimbi ewuketshezi iqhuba ichibi elincibilikisiwe eliwuketshezi ukuthi lidlule odongeni lwangaphambili. Imbobo yokhiye iya ngasemsileni wechibi elincibilikisiwe, ikhuphuka phezulu njengomthombo ovela ngemuva futhi ithinta ubuso bechibi elincibilikisiwe eliwumsila. Ngesikhathi esifanayo, ngenxa yokucindezeleka kobuso (uma izinga lokushisa lokucindezeleka kobuso liphansi, kulapho umthelela uba mkhulu khona), insimbi ewuketshezi echibini elincibilikisiwe elinomsila idonswa ukucindezeleka kobuso ukuze iye emaphethelweni echibi elincibilikisiwe, iqina njalo. Insimbi ewuketshezi engaqina esikhathini esizayo ijikeleza emuva iye emsileni wembobo yokhiye, njalo njalo.
Umdwebo weskimu wokushisela okujulile kwe-laser keyhole: A: Isiqondiso sokushisela; B: Ugongolo lwe-laser; C: Imbobo Eyinhloko; D: Umhwamuko wensimbi, i-plasma; E: Igesi evikelayo; F: Udonga lwangaphambili lwe-Keyhole (ukugaya ngaphambi kokuncibilika); G: Ukugeleza okuvundlile kwezinto ezincibilikisiwe ngendlela ye-keyhole; H: Isixhumi esibonakalayo sokuqina kwechibi elincibilikisiwe; I: Indlela yokugeleza eyehlayo yechibi elincibilikisiwe.
Inqubo yokusebenzisana phakathi kwe-laser nezinto: I-laser isebenza ebusweni bezinto, ikhiqize ukufudumeza okukhulu. Izinto ziqala zishiswe, zincibilike, futhi ziphele. Ngesikhathi senqubo yokuhwamuka okukhulu, umusi wensimbi uya phezulu ukuze unikeze ichibi elincibilikisiwe ingcindezi yokubuyela emuva ehlayo, okuholela embobeni yokhiye. I-laser ingena embobeni yokhiye futhi idlula izinqubo eziningi zokukhipha nokungenisa, okuholela ekuhlinzekweni okuqhubekayo komphunga wensimbi ogcina imbobo yokhiye; I-laser isebenza kakhulu odongeni lwangaphambili lwembobo yokhiye, futhi ukuhwamuka kwenzeka kakhulu odongeni lwangaphambili lwembobo yokhiye. Ingcindezi yokubuyela emuva isunduza insimbi ewuketshezi odongeni lwangaphambili lwembobo yokhiye ukuze izungeze imbobo yokhiye iye emsileni wechibi elincibilikisiwe. Uketshezi oluhamba ngesivinini esikhulu oluzungeze imbobo yokhiye luzothinta ichibi elincibilikisiwe liye phezulu, lwakha amagagasi aphakanyisiwe. Bese, luqhutshwa ukucindezeleka kobuso, luya emaphethelweni futhi luqine kulowo mjikelezo. Ukuqhekeka kwenzeka kakhulu emaphethelweni okuvulwa kwembobo yokhiye, kanti insimbi ewuketshezi odongeni lwangaphambili izodlula imbobo yokhiye ngesivinini esikhulu futhi ithinte isikhundla sechibi elincibilikisiwe odongeni lwangemuva.
