I-Handheld Laser Welding
Umphumela omuhle wegesi efanelekile
E-laser welding, ukukhetha igesi okuvikela kungaba nomthelela omkhulu ekwakhekeni, ikhwalithi, ukujula nobubanzi bomthungo we-weld. Esikhathini esiningi samacala, ukwethulwa kwegesi evikelayo kunomthelela omuhle ku-Weld Seam. Kodwa-ke, ingaba nemiphumela emibi. Imiphumela emihle yokusebenzisa igesi efanelekile yokuvikela yiminyaka elandelayo:
1. Ukuvikelwa okusebenzayo kwechibi leWeld
Ukwethulwa okufanele kwegesi evikelayo kungavikela ngempumelelo ichibi le-weld kwi-oxidation noma kuvikele ne-oxidation ngokuphelele.
2. Ukuncishiswa kokudla okudlalayo
Ukwethula kahle igesi evikelayo kunganciphisa ngokuphumelelayo kokupakisha ngesikhathi senqubo ye-welding.
3. Ukwakheka okufanayo komthungo we-weld
Ukwethulwa okufanele kwegesi evikelayo kukhuthaza ukusakazeka kwechibi leWeld ngesikhathi sokuqina, okuholela ekulweni komfaniswano kanye ne-aest.
4. Ukwanda kokusetshenziswa kwe-laser
Ukwethula kahle igesi evikela kunganciphisa ngempumelelo umphumela wokuvikela we-per vapor yensimbi noma amafu we-plasma e-laser, ngaleyo ndlela akhuphule ukusebenza kahle kwe-laser.
5. Ukwehliswa kwe-welld popoju
Ukwethula kahle igesi yokuvikela kunganciphisa ngempumelelo ukwakheka kwama-pores wegesi ku-Weld Seam. Ngokukhetha uhlobo lwegesi olufanele, isilinganiso se-Flow, kanye nendlela yesingeniso, imiphumela emihle ingatholakala.
Noma kunjalo,
Ukusetshenziswa okungafanele kwegesi evikelayo kungaba nemiphumela eyingozi ekushiseni. Imiphumela emibi ifaka:
1. Ukuwohloka komthungo we-weld
Ukwethulwa okungalungile kwegesi evikelayo kungahle kube nomphumela wekhwalithi yomthungo empofu.
2. Ukuqhekeka futhi kuncishiswe izakhiwo zemishini
Ukukhetha uhlobo lwegesi olungalungile kungaholela ekuqhekekeni komthungo we-weld futhi kwehlise ukusebenza kwemishini.
I-3. Ukwanda i-oxidation noma ukuphazamiseka
Ukukhetha isilinganiso segesi esingalungile, kungaba phezulu kakhulu noma kuphansi kakhulu, kungaholela ekuqhubekeni kwe-opidation yocingo lwe-weld seam. Kungadala futhi ukuphazamiseka okukhulu kwensimbi ebilisiwe, okuholela ekuweni noma ukwakheka okungalingani kwesithumbi seWeld.
4. Ukuvikelwa okunganele noma umthelela omubi
Ukukhetha indlela ye-Geation Wennotion engalungile kungaholela ekuvikelweni okunganele komthungo we-weld noma ngisho nomthelela omubi ekwakhekeni komthungo we-weld.
5. Ithonya ekujuleni kwamandla
Ukwethulwa kwegesi evikelayo kungaba nomthelela othile ekujuleni kwe-weld, ikakhulukazi e-welding yepuleti elincane, lapho kuthambisa khona ukunciphisa ukujula kwe-wald.

Izinhlobo zamagesi wokuvikela
Amagesi asetshenziswa ngokuvamile eLaser Welding angama-nitrogen (N2), i-Argon (AR), ne-Helium (He). Lawa magesi anezakhiwo ezihlukile zomzimba nezamakhemikhali, eziphumela emiphumeleni ehlukile ku-Weld Seam.
1. I-Nitrogen (N2)
I-N2 inamandla alinganiselayo ama-Ionization amandla, aphakeme kune-AR futhi aphansi kunaye. Ngaphansi kwesenzo se-laser, ihlangana nge-degree elinganiselayo, yehlisa ngempumelelo ukwakheka kwamafu we-plasma nokwandisa ukusetshenziswa kwe-laser. Kodwa-ke, i-nitrogen ingaphendula ngamakhemikhali nge-aluminium alloys nensimbi yekhabhoni emazingeni okushisa athile, akha ama-nitrides. Lokhu kungakhuphula ubucwebe futhi kunciphise ubulukhuni bamathumbu wezempi, kuthinta kabi izakhiwo zalo zemishini. Ngakho-ke, ukusetshenziswa kwe-nitrogen njengegesi evikelayo ye-aluminium alloys kanye nama-welds wensimbi ye-carbon akunconywa. Ngakolunye uhlangothi, i-nitrogen ingasabela ngensimbi engenacala, yakha ama-nitrides athuthukisa amandla okuhlanganiswa kwe-weld. Ngakho-ke, i-nitrogen ingasetshenziswa njengegesi evikelayo yensimbi engenacala.
2. I-Arron Gas (AR)
I-Argon gesi inamandla aphansi kakhulu ama-ionization amandla, okuholela ngezinga eliphakeme le-ionization ngaphansi kwesenzo se-laser. Lokhu akufanele ukulawula ukwakheka kwamafu we-plasma futhi kungaba nomthelela othile ekusetshenzisweni okusebenzayo kwama-lasers. Kodwa-ke, i-argon inokuvuselelwa okuphansi kakhulu futhi akunakwenzeka ukuthi iphendukezeke ngamakhemikhali ngezinsimbi ezijwayelekile. Ngaphezu kwalokho, i-Argon iyabiza kakhulu. Ngaphezu kwalokho, ngenxa yobukhulu bayo obuphakeme, i-argen icwila ngaphezulu kwechibi leWeld, ihlinzeka ngokuvikelwa okungcono echibini leWeld. Ngakho-ke, ingasetshenziswa njengegesi evamile yokuvikela.
3. I-Helium Gas (He)
I-Helium gesi inamandla aphezulu kakhulu ama-ionization, okuholela ezingeni eliphansi kakhulu le-ionization ngaphansi kwesenzo se-laser. Ivumela ukulawulwa okungcono ukwakheka kwamafu we-plasma, futhi ama-lasers angaxhumana ngempumelelo nezinsimbi. Ngaphezu kwalokho, i-helium inokuvuselela okuphansi kakhulu futhi ayisebenzi kalula amakhemikhali ngezinsimbi, okwenza kube yigesi enhle kakhulu yokuvikelwa kwe-weld. Kodwa-ke, izindleko ze-helium ziphezulu, ngakho-ke akunakusetshenziswa ekukhiqizeni inqwaba yemikhiqizo. Kuvame ukusetshenziswa ocwaningweni lwesayensi noma ngemikhiqizo engezwe kakhulu.

Izindlela zokwethula igesi evikelekile
Njengamanje, kunezindlela ezimbili eziphambili zokwethula igesi Evikelekile: I-Off-Assage Side Blowing and Coaxial Shielding Gas, njengoba kukhonjisiwe kuMfanekiso 1 noMfanekiso 2, ngokulandelana.
Umdwebo 1: Uhlangothi lwe-Assud-assung lushaya igesi evikelekile
Umdwebo 2: Igesi Evikelekile Yokuvikela
Ukukhetha phakathi kwezindlela ezimbili zokushaya kuncike ekucabangeni okuhlukahlukene. Ngokuvamile, kunconywa ukusebenzisa indlela ye-Off-Assage Side Blowing indlela yokuvikela igesi.

Izimiso zokukhetha indlela yokwethula igesi evikelayo
Okokuqala, kubalulekile ukucacisa ukuthi igama elithi "oxidation" lama-welds liyinkulumo ekhanyayo. Ngomqondo othile, kubhekiswa ekuwohlokeni kwekhwalithi ye-welld ngenxa yokusabela kwamakhemikhali phakathi kwezinsimbi zensimbi nezengozi emoyeni, njenge-oksijini, i-nitrogen, ne-hydrogen.
Ukuvimbela i-axidation yeWelld kuhilela ukunciphisa noma ukugwema ukuxhumana phakathi kwalezi zinto eziyingozi kanye nensimbi yokushisa eshisa kakhulu. Lesi simo sokushisa esiphakeme sifaka hhayi kuphela i-molten welven pool yensimbi kodwa futhi sonke isikhathi kusuka lapho insimbi ye-weld incibilika kuze kube yilapho ichibi liqina futhi izinga lokushisa laso lincipha ngaphansi komkhawulo othile.
Isibonelo, ekushiseni kwama-alloys titanium, lapho izinga lokushisa lingaphezulu kwama-300 ° C, ukumunca ngokushesha kwe-hydrogen kwenzeka; Ngaphezulu kwama-450 ° C, ukumunca i-oksijini okusheshayo kwenzeka; Futhi ngenhla kwama-600 ° C, ukumunca okusheshayo kwe-nitrogen kwenzeka. Ngakho-ke, ukuvikelwa okusebenzayo kuyadingeka ku-Titanium Alloy Weld ngesikhathi sesigaba lapho kuqinisa futhi izinga lokushisa kwalo kuncipha ngaphansi kuka-300 ° C ukuvikela i-oxidation. Ngokusekelwe encazelweni engenhla, kuyacaca ukuthi ukushaywa yigesi okuvikelayo kudinga ukuhlinzeka ngokuvikela hhayi kuphela echibini le-weld ngesikhathi esifanele kodwa futhi nasesifundeni esiqinile seWeld. Ngakho-ke, indlela eseceleni kwe-Assud-assung ekhonjiswe kuMfanekiso 1 ngokuvamile incanyelwa ukuthi inikezela ukuvikelwa okubanzi uma kuqhathaniswa nendlela yokuvikelwa ye-coaxial ekhonjiswe kuMfanekiso 2. Kodwa-ke, ngemikhiqizo ethile ethile, ukukhetha kwendlela kudinga ukwenziwa ngokuya ngesakhiwo somkhiqizo nokucushwa okuhlanganyelwe.

Ukukhetha okuthile kwendlela yokwethula igesi evikelayo
1. I-Strong-Line Weld
Uma ukwakheka kwe-weld yomkhiqizo kuqondile, njengoba kukhonjisiwe kuMdwebo 3, futhi ukucushwa okuhlanganyelwe kufaka phakathi amalunga we-butt, amajoyina ama-Fillit, ama-welds we-fillet, noma i-tillet ama-welds, noma i-baltat ama-welds, le ndlela ekhethwayo ye-axis eseceleni okuboniswe kuyo Umdwebo 1.
Umdwebo 3: I-Straight-Line Weld
2. I-Planethi elivaliwe le-geometry weld
Njengoba kukhonjisiwe kuMdwebo 4, i-Weld kulolu hlobo lomkhiqizo inesimo seplanethi esivaliwe, njenge-polygonal, noma ukwakheka komugqa ohlukahlukene. Ukucushwa okuhlangene kungafaka amalunga we-butt, amalunga we-LAP, noma ama-welds. Ngalolu hlobo lomkhiqizo, indlela ekhethwayo ukusebenzisa igesi evikela ama-coaxial eboniswe kuMfanekiso 2.
Umdwebo 4: Planethi elivalekile le-geometry weld
Ukukhethwa kwegesi evikelekile yePlanethi elivalekile le-geometry ama-welds kuthinta ngqo ikhwalithi, ukusebenza kahle, kanye nezindleko zokukhiqizwa kwe-welding. Kodwa-ke, ngenxa yokwehlukahluka kwezinto zokwehlukanisa, ukukhethwa kwegesi ye-welding kuyinkimbinkimbi ngezinqubo zangempela zokufaka izinsimbi. Kudinga ukucatshangelwa okuphelele kwezinto zokwehlukanisa, izindlela ze-welding, izikhundla ze-welding, kanye nomphumela ofiselekayo we-welding. Ukukhethwa kwegesi elungele kakhulu i-welding kunganqunywa ngokuhlolwa kwe-welding ukufeza imiphumela ephelele yokufaka.
