Izinto Ezibalulekile Okufanele Uzazi Ngaphambi KokuDibela
Ukushisela nge-laser kuyindlela yokushisela enembayo ephezulu esebenzisa ugongolo lwe-laser ukuncibilikisa i-material ye-workpiece bese yakhe i-weld ngemva kokupholisa. Ku-laser welding, igesi idlala indima ebalulekile. Igesi evikelayo ayithinti nje kuphela ukwakheka kwe-welding seam, ikhwalithi ye-welding seam, ukungena kwe-welding seam, nobubanzi bokungena kodwa futhi ithinta ngokuqondile ikhwalithi nokusebenza kahle kwe-laser welding.Imaphi amagesi adingekayo ukuze kushiswe i-laser?Lesi sihloko sizobheka kabanziukubaluleka kwamagesi we-laser welding, amagesi asetshenziswayo, nalokho akwenzayo.Sizophinde sincomethe best laser welding umshiningokwezidingo zakho.
Phakathi nenqubo ye-laser welding, i-laser-high-density laser beam igxile endaweni yokushisela ye-workpiece, okubangela ukuncibilika ngokushesha kwezinto ezingaphezulu kwendawo yokusebenza. Igesi iyadingeka ngesikhathi sokushisela i-laser ukuvikela indawo yokushisela, ukulawula izinga lokushisa, ukuthuthukisa ikhwalithi ye-weld, nokuvikela uhlelo lwe-optical. Ukukhetha uhlobo olufanele lwegesi kanye nemingcele yokuhlinzeka kuyizici ezibalulekile ekuqinisekiseni inqubo ye-laser welding ephumelelayo futhi ezinzile kanye nokuthola imiphumela yekhwalithi ephezulu yokushisela.
1. Ukuvikelwa Kwezindawo Zokushisela
Phakathi nenqubo yokushisela i-laser, indawo yokushisela ibonakala endaweni yangaphandle futhi ithinteka kalula umoya-mpilo namanye amagesi emoyeni.
I-oksijeni ibangela ukusabela kwe-oxidation okungase kuholele ekunciphiseni ikhwalithi ye-weld, nokudala ama-pores kanye ne-inclusions. I-weld ingavikelwa ngokuphumelelayo ekungcoleni komoya-mpilo ngokunikeza igesi efanelekile, ngokuvamile igesi engasebenzi njenge-argon, endaweni yokushisela.
