Ukuwelda kweLaser
Kwinkalo yoqhagamshelo lwezinto eziphathekayo, i-laser welding yamandla aphezulu iphuhliswe ngokukhawuleza, ngakumbi kukwenziwa kweemoto zemveli kunye nokuveliswa kwemoto yamandla amatsha. Kwixesha elizayo, imfuno kwishishini le-aerospace, ishishini lokwakha iinqanawa, ishishini lepetrochemical kunye neminye imimandla iya kunyuka ngokuthe ngcembe, ikhuthaza uphuculo lwetekhnoloji yamashishini anxulumeneyo.
01 Ishishini lemveli lokwenziwa kweemoto
Okwangoku, elona candelo likhulu leshishini le-laser welding likushishino lokuvelisa iimoto, kwaye le meko ayizukutshintsha kule minyaka imbalwa izayo, kwaye intengiso iya kuqhubeka nokugcina imfuno enkulu. Itekhnoloji ye-laser welding ibandakanya i-laser self fusion welding, i-laser filler wire fusion welding, i-laser filler wire brazing, i-remote scanning welding, i-laser swing welding, njl. , ukuze kuqatshelwe ubunzima bokukhanya, ukonga amandla, ukhuseleko lokusingqongileyo kunye nokhuseleko lwesithuthi [1]. Ukuveliswa kweemoto zanamhlanje ngokuqhelekileyo kuthatha indlela yomgca wemveliso ozenzekelayo. Kungakhathaliseki ukuba yiyiphi ikhonkco enengozi yokuvala, iya kubangela ilahleko enzima, ekwabeka phambili iimfuno eziphezulu zokuzinza kunye nokuthembeka kwezixhobo kwikhonkco nganye yokuvelisa.
Njengeyunithi engundoqo yezixhobo zokuwelda i-laser, i-laser idinga ukuba nozinzo oluphezulu lwamandla emveliso, itshaneli ezininzi, i-anti ephezulu ye-anti ephezulu ye-anti ephezulu yokusabela, njl njl. URuike Laser wenze umsebenzi omninzi kule ndawo. kwaye ivelise izixhobo zokuwelda ezizinzileyo nezithembekileyo.
02 Ushishino lokwenziwa kweemoto zamandla amatsha
Ishishini elitsha lezithuthi zamandla likhula ngokukhawuleza, ngokukhula okuthe gqolo kwiintengiso zehlabathi kunye nasekhaya. Imfuno yamacandelo ayo angundoqo, afana neebhetri zamandla kunye neenjini zokuqhuba, nayo iyakhula;
Nokuba kukwenziwa kwebhetri yamandla okanye iimoto zokuqhuba, kukho imfuno enkulu yelaser welding. Izinto eziphambili zezi bhetri zamandla, ezifana nebhetri yesikwere, ibhetri ye-cylindrical, ibhetri yephakheji ethambileyo kunye nebhetri ye-blade, i-aluminium alloy kunye nobhedu obomvu. I-Hair Pin motor yindlela yokuphuhlisa ikamva lemoto yokuqhuba. I-windings kunye neebhulorho zale moto zizinto zonke ezibomvu zobhedu. Ukuwelda kwezi zimbini "izixhobo eziphezulu zokubonisa i-anti" bekusoloko kuyingxaki. Nangona i-laser welding isetyenzisiweyo, kusekho iindawo zentlungu - ukubunjwa kwe-weld, ukusebenza kakuhle kwe-welding kunye ne-welding spatter.
Ukuze kulungiswe ezi ngxaki, abantu baye baqhuba uphando oluninzi, kubandakanywa ukuphononongwa kwenkqubo ye-welding, uyilo lwe-welding joints [2], njl. ukuphuculwa, kunye nokusebenza kakuhle kwe-welding kunokuphuculwa kwinqanaba elithile; Ngoyilo lweendawo ezahlukeneyo zokuwelda ezikhethekileyo, ezinje ngeendawo zokuwelda, i-welding ye-welding edibeneyo ye-laser, njl., ukubunjwa kwe-weld, i-welding spatter kunye nokusebenza kakuhle kwe-welding kunokuphuculwa kakhulu. Kodwa ngokukhula okukhawulezayo kwemfuno, ukusebenza kakuhle kwe-welding akukwazi ukuhlangabezana neemfuno. Iinkampani ezinkulu zomthombo wokukhanya kwelaser ziye zazisa iilaser ezihlengahlengiswayo ngokuphuculwa kobugcisa beelases. Le laser ineziphumo ezimbini ze-laser coaxial beam, kwaye umlinganiselo wamandla kwezi zimbini unokuhlengahlengiswa ngokuthanda. Xa udibanisa i-aluminium alloy kunye nobhedu obomvu, inokufikelela ngokufanelekileyo kunye nokutshiza isiphumo se-welding samahhala, ukuhlangabezana ngokupheleleyo neemfuno zangoku zeshishini lemoto yamandla entsha, eya kuba yi-laser eqhelekileyo kwishishini kwiminyaka embalwa ezayo.
03 Intsimi yokuwelda yeepleyiti eziphakathi nezityebileyo
Ukuwelda kweepleyiti eziphakathi kunye nezingqindilili yeyona ndlela iphambili yokuwela i-laser kwixa elizayo. Kwi-aerospace, i-petrochemical, ulwakhiwo lweenqanawa, izixhobo zamandla enyukliya, ezothutho zikaloliwe kunye namanye amashishini, imfuno yokuwelda iipleyiti eziphakathi nezingqindilili inkulu. Kwiminyaka embalwa edlulileyo, umda ngamandla, ixabiso kunye neteknoloji ye-welding ye-laser, ukusetyenziswa kunye nokukhuthazwa kwe-laser welding kula mashishini kucotha kakhulu. Kwiminyaka emibini yakutshanje, imfuno yophuculo lwemizi-mveliso kunye nokuphuculwa kwemveliso yeshishini laseTshayina iye yangxamiseka ngakumbi. Ukuphucula umgangatho kunye nokusebenza kakuhle yimfuno eqhelekileyo yazo zonke iinkalo zobomi. I-laser arc hybrid welding ithathwa njengenye yezona teknoloji zithembisayo zokuwelda ipleyiti ephakathi kunye nengqindilili.
