Inkqubo ye-laser welding
Ixabiseke kakhulu kwaye isetyenziswa ngokubanzi kushishino lweemoto, apho iiphaneli zeemoto zingomnye weendidi ezintlanu eziphambili ze-laser welding.
Isetyenziswa ezimotweni, inokunciphisa ubunzima bomzimba wemoto, iphucule ukuchaneka kwendibano yomzimba wemoto, inyuse ukuqina komzimba wemoto, kwaye inciphise iindleko zesitampu kunye nendibano kwinkqubo yokwenziwa komzimba wemoto.
Izixhobo zokuwelda iXinfa zineempawu zomgangatho ophezulu kunye nexabiso eliphantsi. Ngeenkcukacha, nceda undwendwele:Abavelisi beWelding & Cutting-China Welding & Cutting Factory & Suppliers (xinfatools.com)
Inkqubo ye-laser self-fusion stack welding yeendawo zepaneli yemoto
Xa i-laser beam kunye noxinzelelo lwamandla olufikelela kuluhlu oluthile (106 ~ 107 W / cm2) lukhupha umphezulu wezinto eziphathekayo, izinto eziphathekayo zithatha amandla okukhanya kwaye ziguqule amandla okushisa. Izinto eziphathekayo ziyafudumala, zinyibilike, kwaye zifakwe ngumphunga, zivelise ubuninzi bentsimbi yomphunga, ophuma phezu komhlaba. Phantsi kwamandla okusabela okwenziwa yilaser, ulwelo lwesinyithi olunyibilikisiweyo lutyhalwa lujikeleze ukwenza imingxuma. Njengoko i-laser iqhubeka i-irradiated, imigodi ingena nzulu. Xa i-laser iyeka ukuntywizisa, ulwelo olutyhidiweyo olujikeleze imingxuma lubuyela umva luze luphole luqine. Weld izixhobo zokusebenza ezimbini kunye.
Izinto ezichaphazela i-laser welding
1. Amandla eLaser
Kukho i-laser energy density threshold kwi-laser welding. Ngezantsi kweli xabiso, kuphela ukunyibilika komphezulu we-workpiece kwenzeka, kwaye ubunzulu bokungena bunzulu kakhulu, oko kukuthi, i-welding yenziwa ngohlobo oluzinzileyo lokuqhuba ukushisa; emva kokuba eli xabiso lifikeleleke okanye ligqithisiwe, i-plasma iya kuveliswa, nto leyo ibonakaliso kunye nenkqubela phambili ye-stable ye-welding yokungena, ubunzulu bokungena buya kwandiswa kakhulu. Ukuba amandla e-laser angaphantsi kulo mqobo kwaye uxinano lwamandla e-laser luncinci, ukungena okungonelanga kuya kwenzeka kwaye inkqubo ye-welding ayiyi kuzinza.
2. Isantya se-welding
Isantya se-welding sinempembelelo enkulu kubunzulu bokungena. Ukwandisa isantya kuya kwenza ukuba ukungena kungabi nzulu, kodwa ukuba isantya siphantsi kakhulu, kuya kubangela ukunyibilika okugqithisileyo kwezinto kunye ne-welding ye-workpiece. Ngoko ke, kukho uluhlu olufanelekileyo lwesantya se-welding kwizinto ezithile ezinegunya elithile le-laser kunye nobukhulu obuthile, kunye nokungena okuphezulu kunokufumaneka kwixabiso elihambelana nesantya.
3. Defocus isixa
Ukugcina uxinaniso lwamandla olwaneleyo, indawo ekugxilwe kuyo ibalulekile. Kwinqwelomoya nganye kude nogxininiso lwelaser, ukuhanjiswa koxinano lwamandla kuyafana. Kukho iindlela ezimbini ze-defocus: i-positive defocus kunye ne-negative defocus. Xa inqwelomoya ekugxilwe kuyo ingaphezulu kwesixhobo sokusebenza, i-positive defocus, kwaye xa ingaphezulu kwesixhobo sokusebenza, i-negative defocus. Utshintsho kwi-defocus luchaphazela ngokuthe ngqo ububanzi kunye nobunzulu be-weld.
4. Igesi ekhuselayo
Ngexesha lenkqubo ye-laser welding, iigesi ezinert zihlala zisetyenziselwa ukukhusela ichibi elityhidiweyo, kodwa kwizicelo ezininzi, iigesi ezinje ngeargon, initrogen, kunye nehelium zihlala zisetyenziselwa ukukhusela i-workpiece kwi-oxidation ngexesha lenkqubo ye-welding kunye nokuvuthela kude. iplasma.
