Kwi-laser welding, igesi ekhuselayo iya kuchaphazela ukubunjwa kwe-weld, umgangatho we-weld, ubunzulu be-weld kunye nobubanzi be-weld.Kwiimeko ezininzi, ukuvuthela igesi ekhuselayo kuya kuba nefuthe elihle kwi-weld, kodwa kunokuzisa iziphumo ezibi.
1. Ukuvuthela ngokuchanekileyo kwigesi ekhuselayo kuya kukhusela ngokufanelekileyo i-weld pool ukunciphisa okanye ukuphepha i-oxidation;
2. Ukuvuthela ngokuchanekileyo kwigesi ekhuselayo kunokunciphisa ngokufanelekileyo i-splash eyenziwe kwinkqubo ye-welding;
3. Ukuvuthela okuchanekileyo kwigesi ekhuselayo kunokwenza i-weld pool solidification isasazeke ngokulinganayo, yenza i-weld forming uniform kwaye ihle;
4. Ukuvuthelwa ngokufanelekileyo kwegesi ekhuselayo kunokunciphisa ngempumelelo impembelelo yokukhusela iplamu yomphunga wesinyithi okanye ifu leplasma kwi-laser, kunye nokunyusa izinga lokusetyenziswa kwelaser;
5. Ukuvuthela ngokufanelekileyo kwegesi yokukhusela kunokunciphisa ngokufanelekileyo i-porosity ye-weld.
Ngethuba nje uhlobo lwegesi, ukuhamba kwegesi kunye nemodi yokuvuthela kukhethwe ngokuchanekileyo, umphumo ofanelekileyo unokufumaneka.
Nangona kunjalo, ukusetyenziswa kakubi kwegesi yokukhusela kunokuchaphazela kakubi i-welding.
Imiphumo emibi
1. Ukuvuthelwa ngokungafanelekanga kwerhasi ekhuselayo kunokukhokelela kwi-weld engalunganga:
2. Ukukhetha uhlobo olungalunganga lwerhasi kunokukhokelela kwiintanda kwi-weld kunye nokunciphisa iimpawu zemishini ye-weld;
3. Ukukhetha isantya sokuvuthela kwerhasi engalunganga kunokukhokelela kwi-weld oxidation enzulu (nokuba isantya sokuhamba sikhulu kakhulu okanye sincinci kakhulu), kwaye kunokubangela ukuba isinyithi se-weld pool siphazamiseke kakhulu ngamandla angaphandle, okukhokelela ekuweni kwe-weld okanye ukubumba okungalinganiyo;
4. Ukukhetha indlela engafanelekanga yokuvuthela igesi kuya kukhokelela ekungaphumeleli kwempembelelo yokukhusela i-weld okanye ngokusisiseko akukho siphumo sokukhusela okanye sibe nefuthe elibi kwi-weld forming;
5. Ukuvuthela kwi-gas ekhuselayo kuya kuba nefuthe elithile kwi-weld deep, ngakumbi xa i-plate encinci idibeneyo, iya kunciphisa ubunzulu be-weld.
Uhlobo lwegesi yokukhusela
Iigesi ze-laser ezisetyenziswa ngokuqhelekileyo zokukhusela i-welding ziyi-N2, i-Ar, Yena, iipropati zakhe zomzimba kunye neekhemikhali zihluke, ngoko umphumo we-weld uhluke.
1. N2
Amandla e-ionization ye-N2 iphakathi, iphezulu kune-Ar kwaye iphantsi kunaleyo ye-He.Iqondo le-ionization ye-N2 liqhelekileyo phantsi kwesenzo se-laser, enokunciphisa ngcono ukubunjwa kwefu le-plasma kwaye ngaloo ndlela yandise izinga lokusetyenziswa kwe-laser.Nitrogen inokusabela nge-aluminium alloy kunye ne-carbon steel kwiqondo lokushisa elithile, elivelisa i-nitride. iya kuphucula i-brittleness ye-weld, kunye nokunciphisa ukuqina, okuya kuba nefuthe elibi kakhulu kwiipropati ze-mechanical ze-weld joint, ngoko ke akukhuthazwa ukusebenzisa i-nitrogen ukukhusela i-aluminium alloy kunye ne-carbon steel welds.
I-nitrogen eveliswa yi-chemical reaction ye-nitrogen kunye nensimbi engenasici inokuphucula amandla e-weld joint, eya kuba luncedo ekuphuculweni kweepropati ze-mechanical weld, ngoko ke i-nitrogen ingasetyenziselwa igesi yokukhusela xa i-welding steel stainless steel.
2. Ar
Amandla e-ar ionization xa kuthelekiswa nobuncinci, phantsi kwefuthe le-laser ionization degree iphezulu, ayilungele ukulawula ukubunjwa kwelifu leplasma, inokusetyenziswa ngokufanelekileyo kwe-laser ukuvelisa isiphumo esithile, kodwa umsebenzi we-Ar uphantsi kakhulu, kunzima ukuwenza. isabela ngeentsimbi eziqhelekileyo, kwaye ixabiso le-Ar aliphezulu, ukongeza, ukuxinana kwe-Ar likhulu, kunenzuzo kwi-sink kwi-weld pool etyhidiweyo ngasentla, inokukhusela ngcono i-weld pool, ngoko inokusetyenziswa njengesiqhelo. igesi ekhuselayo.
3. Yena
Unamandla aphezulu e-ionization, phantsi kwempembelelo ye-laser ionization degree iphantsi, inokulawula kakuhle ukusekwa kwelifu le-plasma, i-laser inokusebenza kakuhle kwintsimbi, inombolo kawonkewonke ye-WeChat: i-welder encinci, umsebenzi kwaye Uphantsi kakhulu, isiseko asisebenzi ngesinyithi, yigesi elungileyo ekhuselayo, kodwa Ubiza kakhulu, Irhasi ayisetyenziselwa iimveliso zokuvelisa ngobuninzi, kwaye isetyenziselwa uphando lwezenzululwazi okanye iimveliso zokongeza ixabiso eliphezulu kakhulu.
