Inkcazo yeSplash Defect: Splash kwi-welding ibhekisa kumathontsi esinyithi anyibilikisiweyo akhutshwa kwidama elinyibilikisiweyo ngexesha lenkqubo yokuwelda. La mathontsi anokuwa kumphezulu ojikelezileyo wokusebenza, abangele uburhabaxa kunye nokungalingani kumphezulu, kwaye anokubangela ukulahleka komgangatho wedama elinyibilikisiweyo, okubangela ukuqhekeka, iindawo zokuqhuma, kunye nezinye iziphene kumphezulu we-weld ezichaphazela iimpawu zoomatshini ze-weld.
I-Splash in welding ibhekisa kumathontsi esinyithi anyibilikisiweyo akhutshwa kwidama elinyibilikisiweyo ngexesha lenkqubo yokuhlanganisa. La mathontsi anokuwa kumphezulu ojikelezileyo wokusebenza, abangele uburhabaxa kunye nokungalingani kumphezulu, kwaye anokubangela ukulahleka komgangatho wedama elinyibilikisiweyo, okubangela ukuqhekeka, iindawo zokuqhuma, kunye nezinye iziphene kumphezulu wokuhlanganisa ezichaphazela iimpawu zoomatshini zedama.
Uhlu lweSplash:
Ukutshiza okuncinci: Amathontsi okuqina akhoyo kumphetho womthungo we-weld kunye nomphezulu wezinto, ikakhulu echaphazela inkangeleko kwaye ayinampembelelo ekusebenzeni; Ngokubanzi, umda wokwahlula kukuba ithontsi lingaphantsi kwe-20% yobubanzi bokuhlanganiswa komthungo we-weld;
Ukutshiza okukhulu: Kukho ukulahleka komgangatho, okubonakala njengeembobo, iindawo zokuqhuma, ukunqunyulwa, njl.njl. kumphezulu womthungo we-weld, okunokukhokelela kuxinzelelo olungalinganiyo kunye noxinzelelo, okuchaphazela ukusebenza komthungo we-weld. Eyona nto iphambili ijoliswe kolu hlobo lweziphene.
Inkqubo yokwenzeka kweSplash:
I-Splash ibonakaliswa njengokujova kwesinyithi esinyibilikisiweyo echibini elinyibilikisiweyo kwicala elithe nkqo kumphezulu wolwelo lwe-welding ngenxa yokukhawuleziswa okuphezulu. Oku kunokubonwa ngokucacileyo kumfanekiso ongezantsi, apho ikholamu yolwelo iphakama ukusuka kwi-welding melt ize ibole ibe ngamaconsi, yenze i-splashes.
Indawo yesiganeko seSplash
Ukuwelda nge-laser kwahlulwe ngokwe-thermal conductivity kunye nokuwelda okunzulu.
Ukuwelda kokuqhuba ubushushu phantse akukho nto inokwenzeka yokutshiza: Ukuwelda kokuqhuba ubushushu kubandakanya kakhulu ukudluliselwa kobushushu ukusuka kumphezulu wezinto ukuya ngaphakathi, kungekho ntshiza iphumayo ngexesha lenkqubo. Le nkqubo ayibandakanyi ukufuma okukhulu kwesinyithi okanye iimpembelelo zomzimba zesinyithi.
Ukuwelda ngokungena nzulu yeyona meko iphambili apho kwenzeka ukutshiza: Ukuwelda ngokungena nzulu kubandakanya ukufikelela ngqo kwizinto nge-laser, ukudlulisela ubushushu kwizinto ngeemingxuma zesitshixo, kwaye impendulo yenkqubo inamandla, nto leyo eyenza kube yeyona meko iphambili apho kwenzeka ukutshiza.
Njengoko kubonisiwe kumfanekiso ongentla, ezinye iingcali zisebenzisa iifoto ezikhawulezayo kunye neglasi ecacileyo yobushushu obuphezulu ukuze zibone imeko yokuhamba komngxuma wesitshixo ngexesha lokuwelda nge-laser. Kunokufunyaniswa ukuba i-laser ibetha eludongeni lwangaphambili lomngxuma wesitshixo, ityhala ulwelo ukuba luhambe luye ezantsi, idlule umngxuma wesitshixo ize ifikelele emsileni wedama elinyibilikisiweyo. Indawo apho i-laser ifunyanwa khona ngaphakathi komngxuma wesitshixo ayilungiswanga, kwaye i-laser ikwimeko yokufunxwa kweFresnel ngaphakathi komngxuma wesitshixo. Enyanisweni, yimeko yokufunxwa okuninzi kunye nokufunxwa, okugcina ubukho bolwelo lwedama elinyibilikisiweyo. Indawo yokufunxwa kwe-laser ngexesha lenkqubo nganye iyatshintsha nge-engile yodonga lomngxuma wesitshixo, nto leyo ebangela ukuba umngxuma wesitshixo ube kwimeko yokujikajika. Indawo yokukhanyiselwa kwe-laser iyanyibilika, iphele, inyanzeliswa, kwaye iguquke, ngoko ke ukungcangcazela kwe-peristaltic kuya phambili.
Olu thelekiso lukhankanyiweyo apha ngasentla lusebenzisa iglasi ecacileyo enobushushu obuphezulu, nto leyo elingana nombono onqamlezileyo wedama elinyibilikisiweyo. Kaloku, imeko yokuhamba kwedama elinyibilikisiweyo yahlukile kwimeko yokwenyani. Ngenxa yoko, abanye abaphengululi basebenzise iteknoloji yokuqandisa ngokukhawuleza. Ngexesha lenkqubo yokuwelda, idama elinyibilikisiweyo liyaqandiswa ngokukhawuleza ukuze kufunyanwe imeko ekhawulezileyo ngaphakathi kwesitshixo. Kuyabonakala ngokucacileyo ukuba ilaser ibetha udonga lwangaphambili lwesitshixo, yenza inyathelo. Ilaser isebenza kule groove yenyathelo, ityhala idama elinyibilikisiweyo ukuba lihambe liye ezantsi, igcwalisa umsantsa wesitshixo ngexesha lokuhamba phambili kwelaser, kwaye ngaloo ndlela ifumana umzobo wendlela yokuhamba eqikelelweyo yokuhamba ngaphakathi kwesitshixo sedama elinyibilikisiweyo lokwenyani. Njengoko kubonisiwe kumfanekiso ochanekileyo, uxinzelelo lwesinyithi olubuyela umva oluveliswa kukususwa kwesinyithi esinyibilikisiweyo nge-laser luqhuba idama elinyibilikisiweyo ukuba lidlule udonga lwangaphambili. Isitshixo siya ngasemsileni wedama elinyibilikisiweyo, sinyuka phezulu njengomthombo ovela ngasemva kwaye sichaphazele umphezulu wedama elinyibilikisiweyo lomsila. Kwangaxeshanye, ngenxa yoxinzelelo lomphezulu (okukhona ubushushu boxinzelelo lomphezulu buphantsi, kokukhona impembelelo inkulu), isinyithi esilulwelo kwidama elinyibilikisiweyo elinomsila sitsalwa luxinzelelo lomphezulu ukuze siye kumphetho wedama elinyibilikisiweyo, siqhubeka siqina. Isinyithi esilulwelo esinokuqina kwixesha elizayo sijikeleza sibuyela ezantsi emsileni wesitshixo, njalo njalo.
Umzobo wesicwangciso se-laser keyhole welding deep penetration welding: A: Icala lokuwelda; B: Umqadi welaser; C: Umngxuma wesitshixo; D: Umphunga wesinyithi, iplasma; E: Igesi ekhuselayo; F: Udonga lwangaphambili lwekeyhole (ukugaywa ngaphambi kokunyibilika); G: Ukuhamba ngokuthe tye kwezinto ezinyibilikisiweyo ngendlela yekeyhole; H: Ujongano lokuqina kwedama lokunyibilika; I: Indlela yokuhamba ezantsi yedama elinyibilikisiweyo.
Inkqubo yokusebenzisana phakathi kwelaser nezinto: Ilaser isebenza phezu komphezulu wezinto, ivelise ukufudunyezwa okukhulu. Izinto ziyafudunyezwa kuqala, zinyibilike, kwaye ziphele. Ngexesha lenkqubo yokufuma okukhulu, umphunga wesinyithi uya phezulu ukuze unike ichibi elinyibilikisiweyo uxinzelelo lokubuya olusezantsi, okubangela umngxuma wesitshixo. Ilaser ingena kumngxuma wesitshixo kwaye idlule kwiinkqubo ezininzi zokukhupha kunye nokufunxa, okubangela ukuba umphunga wesinyithi uqhubeke ugcina umngxuma wesitshixo; Ilaser isebenza kakhulu eludongeni lwangaphambili lomngxuma wesitshixo, kwaye ukufuma kwenzeka kakhulu eludongeni lwangaphambili lomngxuma wesitshixo. Uxinzelelo lokubuya lutyhala isinyithi esilulwelo eludongeni lwangaphambili lomngxuma wesitshixo ukuze sijikeleze umngxuma wesitshixo siye emsileni wechibi elinyibilikisiweyo. Ulwelo oluhamba ngesantya esiphezulu lujikeleze umngxuma wesitshixo luya kuchaphazela ichibi elinyibilikisiweyo ukuya phezulu, lenze amaza aphakanyisiweyo. Emva koko, luqhutywa kukuxinana komphezulu, luya ngasemphethoni kwaye luqine kumjikelo onjalo. Ukuqhekeka kwenzeka ikakhulu kumphetho wokuvula umngxuma wesitshixo, kwaye isinyithi esilulwelo eludongeni lwangaphambili siya kukhawuleza sidlule umngxuma wesitshixo kwaye sichaphazele indawo yechibi elinyibilikisiweyo eludongeni lwangasemva.
