I-Laser Welding ijolise ikakhulu ekuphuculeni ukusebenza kwe-welding kunye nomgangatho wezinto ezinqabileyo zodonga kunye nenxalenye yokuchaneka. Namhlanje asizukuthetha ngeengenelo ze-serling welding kodwa gxila kwindlela yokusebenzisa iigesi ezikhuselayo kwi-laser yelding yakho.
Kutheni usebenzisa igesi yerhasi ye-ser welling?
Kwi-Laser Welling, igesi ye-Shield iya kuchaphazela i-WOLDS yokwakha i-WOLL, uMgangatho we-WELD, ubunzulu be-Weld, kunye nobubanzi be-Weld. Kwiimeko ezininzi, ukuvuthela igesi encedisiweyo kuya kuba nefuthe elihle kwi-WODT, kodwa inokuzisa iziphumo ezibi.
Xa uvuthuza igesi ye-rield ngokuchanekileyo, iya kukunceda:
✦Khusela ngokufanelekileyo iphuli ye-weld ukunciphisa okanye ukuphepha i-oxidation
✦Ngempumelelo ukunciphisa i-splash eveliswe kwinkqubo ye-welding
✦Ngempumelelo ukunciphisa iipores ze-weld
✦Ncedisa iphuli ye-weld ngokulinganayo ngokulinganayo, ukuze i-Wood Seam iza nomda ococekileyo nogudileyo
✦Iziphumo ezikhuselayo ze-vator yentsimbi yentsimbi okanye ilifu lasePlasma kwiLaser lincitshisiwe ngokufanelekileyo, kwaye iqondo lokusebenza elisebenzayo le-laseres liyanda.
Ngalo lonke ixeshaUhlobo lwegesi ye-Shuel, iRhafu yokuhamba kweRhafu, kunye nokukhethwa kwemodi yokuvuthuzazichanekile, unokufumana ifuthe elifanelekileyo le-welding. Nangona kunjalo, ukusetyenziswa okungachanekanga kwegesi yokukhusela kunokukuchaphazela kakubi i-welding. Usebenzisa uhlobo olungalunganga lwerhasi irhasi inokukhokelela kwi-quids okanye inciphise iipropathi zoomatshini be-welding. Too high or too low a gas flowing rate may lead to more serious weld oxidation and serious external interference of the metal material inside the weld pool, resulting in weld collapse or uneven forming.
Iindidi zerhasi yekhuselo
Iigesi ezikhuselweyo ezisetyenziswayo ze-laser ye-laser ikakhulu ziyi-N2, Ar, kwaye yena. Iipropathi zabo zomzimba kunye neekhemikhali zahlukile, ke iziphumo zabo kwi-welds zahlukile.
I-Nitrogen (N2)
Amandla e-ionsy ye-N2 ilinganiselana, aphezulu kune-AR, kwaye asezantsi kunelo. Ngaphantsi kwe-radiation ye-laser, isidanga sokuphulukana ne-N2 sihlala kwi-keel, enokunciphisa ukunciphisa imeko yelifu yeplasma kwaye inyuse inqanaba lokusetyenziswa kwe-laser. I-Nitrogen inokuphendula nge-Aluminium Alloty kunye ne-carbon yehlaseli kwiqondo lokushisa elithile ukuvelisa i-nitrides, eya kuphucula ubuchule be-WOPROTE kwaye ube nefuthe elibi kwiimpawu zobuchwephesha. Ke ngoko, akucetyiswa ukuba usebenzise i-nitrogen xa i-welding aluminium alloy kunye nentsimbi yekhabhoni.
Nangona kunjalo, impendulo yekhemikhali phakathi kwe-nitrogen kunye nentsimbi engenasitali eveliswe yi-nitrogen inokuphucula amandla omdibaniso we-weld, ngoko ke i-welding yensimbi inokusebenzisa igesi.
Argon (i-AR)
Amandla e-ionsy orgon aphantsi kakhulu, kwaye inqanaba labo le-ion liya kuba phezulu phantsi kwesenzo se-laser. Emva koko, iArgon, njengegesi ekhuselekileyo, ayinakho ukulawula ngokuqulunqa amafu ePlasma, eya kunciphisa iqondo lokusetyenziswa kwe-laser ye-laser. Umbuzo uphakama: Ngaba i-argon umgqatswa ombi wokusetyenziswa kwe-welding njengegesi yokukhusela? Impendulo yile. Ukuba yirhasi ye-inter, iArgon kunzima ukusabela kuninzi lwezinyithi, kwaye i-AR iphantsi ukuze isetyenziswe. Ukongeza, ukuxinana kwe-Ar kuphakame, kuya kuba lula ukuntywila kumphezulu wephuli ye-Wold Molten kwaye kungangcono ukukhusela iphuli ye-WODD, i-argon ingasetyenziswa njengegesi yokukhusela eqhelekileyo.
Helium (yena)
Ngokungafaniyo ne-Argon, i-Helheum inamandla aphezulu e-ionization enokulawula ukwenziwa kwamafu ePlasma amafu ngokulula. Kwangelo xesha, i-helium ayiphenduli naziphi na izinyithi. Kukhetho olululo ngokwenene kwi-ser welling. Ingxaki kuphela kukuba i-helium ibiza kakhulu. Ngeenqaba ezibonelela ngeemveliso zensimbi ezinobunzima, uHelsium uya kongeza isixa esikhulu kwixabiso lemveliso. Yiyo ke i-helium isetyenziswa ngokubanzi kuphando lwesayensi okanye iimveliso ezinexabiso eliphezulu kakhulu.
Ungayibetha njani igesi yenkululeko?
Okokuqala, kufanele ukuba kucace ukuba "i-oxidation" ye-weld ligama eliqhelekileyo, elibhekiswa ngokwesimo se-scocical kuphela, ekhokelela ekuwohlokeni kwe-weld . Ngokuqhelekileyo, intsimbi ye-weld iphendula ngeoksijini, i-nitrogen, kunye ne-hydrogen emoyeni kwiqondo lobushushu elithile.
Ukuthintela i-weld ukusuka ekubeni "oxidd" ifuna ukunciphisa okanye ukuphepha unxibelelwano phakathi kwezinto ezinobungozi kunye nentsimbi ye-WOLD ePool ngaphandle kwentsimbi ye-WOLD inyibilike kude kube nini Isinyithi se-Pollin esinyinyileyo siyaqina kwaye iqondo lobushushu laso lipholile kubushushu obuthile.

Kungcono ukwamkela indlela yegesi yokukhusela i-ceaxial njengoko kubonisiwe kumzobo 2 kolu hlobo lwemveliso.
Ukukhethwa kwerhasi yokukhusela kuchaphazela ngokuthe ngqo umgangatho we-welding, ukusebenza kakuhle, kunye nexabiso lemveliso, kwinkqubo ye-welding, kwinkqubo ye-welding, ekuqwalaseleni igesi ye-welding inzima kwaye ifuna ukuqwalaselwa kwezinto ze-welding, i-welding Indlela, indawo ye-welding, kunye neemfuno zesiphumo seWoldsing. Ngovavanyo lwe-welding, unokukhetha igesi ye-welfling efanelekileyo yokufezekisa iziphumo ezingcono.
Unomdla kwi-laser ye-welling kwaye uzimisele ukufunda indlela yokukhetha igesi enkulu
