Indlela yokusebenzisa igesi ngendlela efanele ku-Laser Welding

Ku-laser welding, igesi evikelayo izothinta ukwakheka kwe-weld, ikhwalithi ye-weld, ukujula kwe-weld nobubanzi be-weld.Ezimweni eziningi, ukuvuthela igesi evikelayo kuzoba nomthelela omuhle ekushiseleni, kodwa kungase futhi kulethe imiphumela emibi.

1. Ukuvuthela okulungile kugesi evikelayo kuzovikela ngokuphumelelayo i-weld pool ukunciphisa noma ukugwema ngisho ne-oxidation;

2. Ukuvuthela okulungile kugesi elivikelayo kunganciphisa ngempumelelo ukuchaphaza okukhiqizwa ohlelweni lokushisela;

3. Ukuvunguza okulungile kugesi evikelayo kungenza ukuqina kwe-weld pool kusakazeke ngokulinganayo, kwenze iyunifomu yokwenza i-weld ibe yinhle;

4. Ukuphephetha ngendlela efanele kwegesi evikelayo kunganciphisa ngempumelelo umphumela wokuvikela umbhobho wensimbi noma ifu le-plasma ku-laser, futhi kukhuphule izinga elisebenzayo lokusebenzisa i-laser;

5. Ukushaywa kahle kwegesi yokuzivikela kunganciphisa ngempumelelo i-porosity ye-weld.

Uma nje uhlobo lwegesi, ukugeleza kwegesi kanye nemodi yokuphefumula kukhethwe ngendlela efanele, umphumela omuhle ungatholakala.

Kodwa-ke, ukusetshenziswa okungalungile kwegesi yokuzivikela nakho kungathinta kabi ukushisela.

Imiphumela emibi

1. Ukuphephetha okungalungile kwegesi evikelayo kungase kuholele ekushiseleleni okubi:

2. Ukukhetha uhlobo olungalungile lwegesi kungase kuholele ekuqhekekeni kwe-weld futhi kunciphise izakhiwo zemishini ze-weld;

3. Ukukhetha izinga lokugeleza kokuphephuka kwegesi okungalungile kungase kuholele ku-oxidation ye-weld eyingozi kakhulu (ukuthi izinga lokugeleza likhulu kakhulu noma lincane kakhulu), futhi kungase kubangele ukuthi insimbi ye-weld pool iphazamiseke kakhulu ngamandla angaphandle, okuholela ekuweni kwe-weld noma. ukubumba okungalingani;

4. Ukukhetha indlela engalungile yokuphephetha kwegesi kuzoholela ekuhlulekeni komphumela wokuvikela we-weld noma ngisho kungabikho umphumela wokuvikela noma kube nomthelela omubi ekubunjweni kwe-weld;

5. Ukuphefumula ngegesi elivikelayo kuzoba nomthelela othile ekujuleni kwe-weld, ikakhulukazi uma ipuleti elincane lishiselwe, kuzonciphisa ukujula kwe-weld.

Uhlobo lwegesi yokuvikela

Amagesi okuvikela ama-laser welding asetshenziswa kakhulu ikakhulukazi yi-N2, Ar, He, izakhiwo zayo ezingokomzimba namakhemikhali zihlukile, ngakho-ke umphumela we-weld nawo uhlukile.

1. N2

Amandla e-ionization we-N2 aphakathi, aphakeme kunalawo e-Ar futhi aphansi kunalawo ka-He.I-ionization degree ye-N2 ivamile ngaphansi kwesenzo se-laser, enganciphisa kangcono ukwakheka kwefu le-plasma futhi ngaleyo ndlela ikhulise izinga lokusebenzisa elisebenzayo le-laser.Nitrogen ingasabela nge-aluminium alloy ne-carbon steel ekushiseni okuthile, ikhiqize i-nitride, ekhiqiza i-nitride. izothuthukisa i-brittleness ye-weld, futhi inciphise ukuqina, okuzoba nomthelela omkhulu omubi ezintweni zemishini ye-weld joint, ngakho-ke akunconywa ukusebenzisa i-nitrogen ukuvikela i-aluminium alloy kanye ne-carbon steel welds.

I-nitrogen ekhiqizwa ukusabela kwamakhemikhali e-nitrogen nensimbi engagqwali ingathuthukisa amandla e-weld joint, okuzoba usizo ekuthuthukisweni kwezakhiwo zemishini ye-weld, ngakho-ke i-nitrogen ingasetshenziswa njengegesi evikelayo lapho kushiselwa insimbi engagqwali.

2. Ar

I-Ar ionization energy isihlobo esincane, ngaphansi komphumela we-laser ionization degree iphakeme, ayisizi ukulawula ukwakheka kwefu le-plasma, ingakwazi ukusetshenziswa okusebenzayo kwe-laser ukukhiqiza umphumela othile, kodwa umsebenzi we-Ar uphansi kakhulu, kunzima ukuwenza. isabela ngezinsimbi ezivamile, futhi izindleko ze-Ar aziphezulu, ngaphezu kwalokho, ukuminyana kwe-Ar kukhudlwana, kunenzuzo kusinki echibini elincibilikisiwe le-weld ngenhla, Ingakwazi ukuvikela kangcono ichibi lokushisela, ukuze lisetshenziswe njengendawo evamile. igesi yokuzivikela.

3. Yena

Unamandla aphezulu kakhulu e-ionization, ngaphansi komphumela we-laser ionization degree iphansi, ingakwazi ukulawula kahle ukwakheka kwefu le-plasma, i-laser ingaba isebenze kahle ensimbi, inombolo yomphakathi ye-WeChat: i-welder encane, umsebenzi futhi Uphansi kakhulu, isisekelo asisabelani nezinsimbi, iyigesi evikelayo yokushisela, kodwa Ibiza kakhulu,Igesi ayisetshenziselwa ukukhiqiza izinto eziningi, futhi Isetshenziselwa ucwaningo lwesayensi noma imikhiqizo ephezulu kakhulu ye-value-added.
