5 Laser Welding Quality Problems & Solutions

Izinkinga ezi-5 zekhwalithi yokushisela nezixazululo

Hlangana nezimo ezahlukahlukene ze-laser welder

Ngokusebenza kahle okuphezulu, ukunemba okuphezulu, umphumela omuhle wokushisela, ukuhlanganiswa okulula okuzenzakalelayo, nezinye izinzuzo, i-laser welding isetshenziswa kabanzi ezimbonini ezahlukahlukene futhi idlala indima ebalulekile ekukhiqizeni izimboni zokushisela insimbi, okubandakanya ezempi, ezokwelapha, i-aerospace, 3C. izingxenye zezimoto, i-mechanical sheet metal, amandla amasha, i-sanitary hardware, nezinye izimboni.

Kodwa-ke, noma iyiphi indlela yokushisela uma ingenalwazi ngesimiso nobuchwepheshe bayo, izokhiqiza amaphutha athile noma imikhiqizo enesici, i-laser welding nayo ihlukile. Ukuqonda okuhle kuphela kwalezi ziphambeko, nokufunda ukugwema lezi ziphambeko, ukudlala kangcono inani le-laser welding, ukucubungula ukubukeka okuhle, kanye nemikhiqizo yekhwalithi enhle. Onjiniyela ngokuqongelela isipiliyoni sesikhathi eside, bafingqa amaphutha athile ajwayelekile we-welding wesixazululo, ukuze kubhekwe ozakwabo bemboni!

1.Imifantu

Imifantu ekhiqizwe ku-laser welding eqhubekayo ikakhulukazi imifantu eshisayo, njengokuqhekeka kwe-crystallization, imifantu ene-liquefied, njll. Isizathu esiyinhloko siwukuthi i-weld ikhiqiza amandla amakhulu okunciphisa ngaphambi kokuqiniswa okuphelele. Ukusebenzisa okokuphakela ngocingo ukugcwalisa izintambo noma ukushisa kuqala ucezu lwensimbi kunganciphisa noma kuqede imifantu eboniswa ngesikhathi sokushisela nge-laser.

2.Izimbotshana ku-weld

I-Porosity iyisici esilula ku-laser welding. Ngokuvamile i-laser welding pool ijulile futhi incane, futhi izinsimbi ngokuvamile zihambisa ukushisa kahle kakhulu futhi zishesha kakhulu. Igesi ekhiqizwe ku-liquid pool encibilikisiwe ayinaso isikhathi esanele sokuphuma ngaphambi kokuba insimbi yokushisela iphole. Icala elinjalo kulula ukuholela ekwakhekeni kwama-pores. Kodwa futhi ngenxa yokuthi indawo yokushisa yokushisela i-laser incane, insimbi ingaphola ngokushesha okukhulu, i-porosity ewumphumela eboniswa ekushiseleni nge-laser ngokuvamile incane kune-fusion yendabuko yokushisela. Ukuhlanza indawo yokusebenza ngaphambi kokushisela kunganciphisa ukuthambekela kwama-pores, futhi isiqondiso sokushaywa kuzophinde kuthinte ukwakheka kwama-pores.

3.Ukuchaphaza

Uma ushisela i-workpiece yensimbi ngokushesha okukhulu, insimbi ewuketshezi ngemuva kwembobo ekhomba phakathi nendawo yokushisela ayinaso isikhathi sokusabalalisa kabusha. Ukuqinisa ezinhlangothini zombili ze-weld kuzokwakha ukuluma. Lapho igebe phakathi kwezingcezu ezimbili zomsebenzi likhulu kakhulu, ngeke kube khona insimbi encibilikisiwe eyanele etholakalayo yokwenza i-caulking, lapho i-welding edge biting nayo izokwenzeka. Esigabeni sokugcina se-laser welding, uma amandla ehla ngokushesha, imbobo kulula ukudilika futhi kubangele ukukhubazeka okufanayo kwe-welding. Amandla ebhalansi angcono kanye nesivinini esinyakazayo sezilungiselelo zokushisela nge-laser kungaxazulula ukukhiqizwa kokuluma onqenqemeni.

4.Undercut

I-splash ekhiqizwa yi-laser welding ithinta kakhulu ikhwalithi ye-weld surface futhi ingangcolisa futhi ilimaze ilensi. I-spatter ihlobene ngokuqondile nokuqina kwamandla, futhi ingancishiswa ngokunciphisa kahle amandla okushisela. Uma ukungena kunganele, isivinini sokushisela singancishiswa.

5.Ukubhidlika kwechibi elincibilikisiwe

Uma ijubane lokushisela lihamba kancane, ichibi elincibilikisiwe likhulu futhi libanzi, inani lensimbi encibilikisiwe liyakhula, futhi ukungezwani okungaphezulu kunzima ukugcina insimbi enzima, isikhungo se-weld sizocwila, senze ukuwa kanye nemigodi. Ngalesi sikhathi, kuyadingeka ukunciphisa ukuminyana kwamandla ngendlela efanele ukuze kugwenywe ukuwa kwechibi elincibilikisiwe.
