Umshini wokushisela we-laser usebenzisa i-high energy laser pulse ukwenza ukushisa ezindaweni ezicashile zezinto ezicutshunguliwe. Amandla azobe esedlulisela ngaphakathi kwezinto ngokudluliswa kokushisa, bese izinto ezisetshenziswayo zizoncibilika zenze ichibi elithile elincibilikisiwe ukuze kuzuzwe injongo yokuncibilika.
Umshini we-laser welding umshini ojwayelekile wokucubungula emkhakheni wemboni. Ngephethini yokusebenza, umshini wokushisela we-laser ungahlukaniswa ngomshini wokushisela we-laser othomathikhi, umshini wokushisela indawo we-laser, umshini wokushisela we-fiber laser nokunye.
Kunezinhlobo eziningi zezinto umshini wokushisela we-laser ongasebenza kuzo. Ukubala okumbalwa:
1.Die steel
Umshini wokushisela we-Lase ungasebenza ngensimbi yokufa yezinhlobo ezilandelayo: S136, SKD-11, NAK80, 8407, 718, 738, H13, P20, W302,2344 njalonjalo. Umphumela wokushisela kulezi zinsimbi zokufa muhle kakhulu.
2.Insimbi yekhabhoni
Njengoba isivinini sokushisisa kanye nesivinini sokupholisa somshini wokushisela i-laser kushesha kakhulu uma usebenza, ukuqhekeka kokushisela kanye nokuzwela kwegebe kuzokhula njengoba amaphesenti ekhabhoni akhula. I-high-medium carbon steel kanye nensimbi evamile ye-alloy kokubili izinsimbi zekhabhoni ezifanele ukusebenza kuzo, kodwa zidinga ukushisisa kwangaphambili nokwelashwa kwangemuva kokushisela ukuze kugwenywe ukuqhekeka kwe-weld.
3.Insimbi engagqwali
Uma iqhathaniswa nensimbi ye-carbon, insimbi engagqwali inesici esiphansi sokushisa kanye nezinga eliphezulu lokumunca amandla. Ukusebenzisa umshini wokushisela we-laser wamandla amancane ukushisela ipuleti elincane lensimbi engagqwali kungafinyelela umbono omuhle wokushisela kanye nokuhlangana okubushelelezi kokushisela ngaphandle kwebhamuza negebe.
4.Ingxube yethusi neyethusi
Kunconywa ukusebenzisa umshini wokushisela we-laser we-high-medium ukuze usebenze nge-alloy yethusi neyethusi njengoba kunzima ukufeza ukujoyina okuphelele nokushisela. I-Hot crack, i-bubble kanye ne-welding stress inkinga evamile ngemva kokushisela.
5.Ipulasitiki
Ipulasitiki evamile umshini wokushisela we-laser ongasebenza kuwo ihlanganisa i-PP, i-PS, i-PC, i-ABS, i-PA, i-PMMA, i-POM, i-PET ne-PBT. Kodwa-ke, umshini wokushisela we-laser awukwenzi’t ngqo kupulasitiki futhi abasebenzisi badinga ukwengeza i-carbon black ku-base material ukuze amandla anele amuncwe njengoba ipulasitiki inezinga eliphansi lokungena kwe-laser.
Ngenkathi umshini wokushisela we-laser usebenza, umthombo we-laser ngaphakathi uvame ukukhiqiza ukushisa okukhulu. Uma lolu hlobo lokushisa lungakwazi ukususwa ngesikhathi, ikhwalithi yokushisela izothinteka, noma okubi nakakhulu, okuholela ekuvaleni kwawo wonke umshini wokushisela we-laser. Kodwa don’ngikhathazeke. S&A I-Teyu iyakwazi ukuhlinzeka ngezixazululo zokupholisa nge-laser zezinhlobo ezahlukene zemishini yokushisela nge-laser±0.1℃,±0.2℃,±0.3℃,±0.5℃ futhi±1℃ ukuzinza kwezinga lokushisa lokukhetha.
