Yiziphi izinqubo ze-laser welding?

I-laser weldingwuhlobo olusha lwendlela yokushisela.I-laser weldingihloselwe kakhulu ukushisela izinto ezinodonga oluncane kanye nezingxenye ezinembayo. Iyakwazi ukubona ukushisela izinqe, i-butt welding, i-stack welding, i-seal welding, njll. Izici zayo yilezi: i-aspect ratio ephezulu, Ububanzi be-seam buncane, indawo ethintekile ukushisa incane, ukuwohloka kuncane, futhi isivinini sokushisela siyashesha. I-weld seam ibushelelezi futhi inhle, futhi akukho ukwelashwa okudingekayo noma izinqubo zokwelashwa ezilula kuphela ezidingekayo ngemva kokushisela. Izinga lokushisela liphezulu futhi awekho ama-pores. Ukungcola kwesisekelo sensimbi kungancishiswa futhi kwenziwe kahle. Isakhiwo singalungiswa ngemuva kokushisela. Amandla nokuqina kwe-weld okungenani kuyalingana noma kudlule ngisho naleyo yensimbi eyisisekelo. Ingalawulwa ngokunembile, indawo yokukhanya okugxilwe kuyo incane, ingabekwa ngokunemba okuphezulu, futhi kulula ukuyibona i-automation. Ingakwazi ukufeza i-welding phakathi kwezinto ezithile ezingafani.

1. I-laser self-fusion welding

I-laser weldingisebenzisa ukuqondisa okuhle kakhulu kanye nokuminyana kwamandla aphezulu we-laser beam ukuze isebenze. I-laser beam igxile endaweni encane ngokusebenzisa uhlelo lwe-optical, yakha umthombo wokushisa ogxile kakhulu endaweni eshiselwe ngesikhathi esifushane kakhulu. indawo, ukuze into ezoshiselwa incibilike futhi yakhe iphuzu eliqinile le-welding kanye ne-welding seam. I-laser welding: i-aspect ratio enkulu; isivinini esikhulu nokunemba okuphezulu; okokufaka okuncane kokushisa kanye ne-deformation encane; i-welding engathinteki; ayithinteki yizinkambu kazibuthe futhi asikho isidingo sokuhlanza.

2. I-laser filler wire welding

I-laser filler wire weldingibhekisela endleleni yokugcwalisa ngaphambili izinto ezithize zokushisela ku-weld bese uzincibilikisa nge-laser irradiation noma ukugcwalisa izinto zokushisela ngenkathi i-laser irradiation ukwenza ijoyinti elishiselwe. Uma kuqhathaniswa ne-non-filler wire welding, i-laser filler wire welding ixazulula inkinga yezidingo eziqinile zokucubungula nokuhlanganisa umsebenzi; ingashisela izingxenye ezinkulu nezikhudlwana ngamandla aphansi; ngokulungisa ukwakheka kwe-filler wire, izakhiwo zesakhiwo sendawo ye-weld zingalawulwa.

3. Ukushisela indiza ye-laser

I-laser welding ekudeibhekisela endleleni yokushisela nge-laser esebenzisa i-galvanometer yokuskena enesivinini esiphezulu ukuze kucutshungulwe ibanga elide lokusebenza. Inokunemba okuphezulu kokuma, isikhathi esifushane, isivinini sokushisela okusheshayo nokusebenza kahle okuphezulu; ngeke iphazamise i-welding fixture futhi inokungcoliswa okuncane kwama-lens optical; amashisela anoma yimuphi umumo angenziwa ngendlela oyifisayo ukuze kwandiswe amandla esakhiwo, njll. Ngokuvamile, i-weld seam ayinaso isivikelo segesi futhi isipatshi sikhulu. Isetshenziswa kakhulu kumapuleti ensimbi anamandla amakhulu, amapuleti ensimbi athathiwe neminye imikhiqizo efana namaphaneli omzimba.

4. I-Laser brazing

I-laser beam ekhishwe yi-laser generator igxile ebusweni bentambo yokushisela futhi ifudumale, ibangele ukuthi ucingo lokushisela luncibilike (insimbi eyisisekelo ayincibiliki), manzisa isisekelo sensimbi, ugcwalise igebe elihlangene, futhi uhlanganise nesisekelo. insimbi ukwenza i-weld ukuze kuzuzwe ukuxhumana okuhle.

5. I-laser swing welding

Ngokunyakazisa ilensi ekhanyayo yangaphakathi yekhanda lokushisela, ukushwibeka kwe-laser kulawulwa ukuze kushukumise ichibi lokushisela, kukhuthaze ukuchichima kwegesi echibini, futhi kucwengisise okusanhlamvu. Ngesikhathi esifanayo, kungase futhi kunciphise ukuzwela laser welding kuya igebe impahla engenayo. Ikakhulukazi kufanelekile ukushisela i-aluminium alloy, ithusi nezinto ezingafani.

6. I-laser arc hybrid welding

I-laser-arc hybrid weldingihlanganisa imithombo yokushisa ye-laser ne-arc enezinto ezibonakalayo ezihluke ngokuphelele kanye nezindlela zokudlulisa amandla ukuze kwakhe umthombo wokushisa omusha futhi ophumelelayo. Izici zokushisela okuxubile: 1. Uma kuqhathaniswa ne-laser welding, ikhono lokuhlanganisa ibhuloho liyathuthukiswa futhi nesakhiwo siyathuthukiswa. 2. Uma kuqhathaniswa ne-arc welding, i-deformation incane, isivinini se-welding siphezulu, futhi ukujula kokungena kukhulu. 3. Sebenzisa amandla omthombo ngamunye wokushisa futhi ulungise ukushoda kwawo, 1+1>2.
