E-laser welding, hlobo luni lwendlela yokushaya esingayikhetha khona, kanjani ukukhetha umgomo wokuvikela igesi?
1) indlela yokushaya
Njengamanje zikhona izindlela ezimbili eziphambili zokushaya igesi evikelayo: enye igesi ehlanzekile eshaywayo, njengoba kukhonjisiwe kuMfanekiso 1; Enye igesi evikela ama-coaxial, njengoba kukhonjisiwe kuMfanekiso 2.
Ungazikhetha kanjani izindlela ezimbili zokushaya ukucubungula okuphelele kwezici eziningi. Ngokuvamile, kunconywa ukusebenzisa indlela eseceleni evikela igesi evikelayo.
2) Umgomo wokukhetha wendlela yokushaya
Okokuqala, kudinga ukucacisa ukuthi lokho okubizwa ngokuthi yi-Weld okuthiwa yi-Weld igama elijwayelekile kuphela. Ngomqondo, kusho ukuthi ukusabela kwamakhemikhali phakathi kwe-weld kanye nezinto eziyingozi emoyeni kuholela ekuwohlokeni kwekhwalithi ye-weld. Iphendula ngamakhemikhali nge-oxygen, i-nitrogen ne-hydrogen emoyeni.
Ukuvimbela i-weld kusuka ekubeni yi- 'oxidized ' ukunciphisa noma ukugwema ukuxhumana kwezinto eziyingozi ezinjalo ngensimbi ye-weld ekushiseni okuphezulu. I-Pool Metal iqinisa futhi izinga lokushisa layo liyehla ngaphansi kokushisa okuthile ngesikhathi.
Ukuhlaziywa kwamacala
Isibonelo, i-titanium alloy welding ingadonsa ngokushesha i-hydrogen lapho amazinga okushisa engaphezulu kwama-300 ° C, ngokushesha anciphise i-oxygen lapho kungaphezulu kwama-300 ° C, ngakho-ke ama-titanium alloy e-C, azokwehla ku-300 ° C konke okulandelayo adinga ukuvikelwa ngempumelelo, uma kungenjalo kuzoba 'oxidized '.
Akunzima ukuyiqonda kusuka encazelweni engenhla yokuthi igesi evikelekile eshaywayo ayidingi kuphela ukuvikela ichibi le-weld ngesikhathi esifanele, ngoba ububanzi be-paraxial buhlotshezwe kakhulu, ngakho-ke uhla lwe-paraxial luboniswe kakhulu, ngakho-ke uhla lwe-paraxial luboniswe kulokho okwenziwa khona indawo lapho i-weld isanda kuqinisekiswa khona.
Okwezinhlelo zokusebenza zobunjiniyela, akuwona wonke imikhiqizo engasebenzisa igesi evikelekile esosimini eseceleni. Kweminye imikhiqizo ethile, kuphela igesi yokuvikela evikelayo engasetshenziswa. Ngokukhethekile, kudinga ukunqunywa kusuka kusakhiwo somkhiqizo nefomu elihlanganyelwe. Ukukhetha okuhlosiwe.
1. Ukukhetha izindlela ezithile zokuvikela igesi ezivikelayo
1) umugqa oqondile weld
Uma ukwakheka komhlaba weWeld komkhiqizo kuqondile, ifomu elihlanganyelwe lingaba yi-butt ehlanganiswe, i-lap ehlanganisiwe, i-angle ye-angle ehlanganisiwe noma i-lap ehlanganisiwe. Ngalolu hlobo lomkhiqizo, kungcono ukusebenzisa indlela yokuvikela igesi ye-Side-Axis Meet Blowing.
2) Plane evaliwe imidwebo
Uma ukwakheka komucu we-weld womkhiqizo kuyindlela evaliwe efana nokujikeleza kwendiza, i-polygon enezindiza, njll. indlela ingcono.
2. Isiphetho
Ukukhethwa kwegesi evikelekile kuthinta ngqo ikhwalithi, ukusebenza kahle kanye nezindleko zokukhiqizwa kwe-welding. Kodwa-ke, ngenxa yokwehlukahluka kwezinto zokwehlukanisa izindwangu, ukukhethwa kwamagesi we-welding nakho kuyinkimbinkimbi kakhulu kwinqubo yangempela ye-welding. Kuyadingeka ukuthi ubheke ngokugcwele izinto zokwehlukaniswa, izindlela ze-welding, izikhundla ze-welding kanye nomphumela odingekayo we-welding, igesi efanelekayo ye-welding edingekayo ngokuhlolwa kwe-welding ukuze uzuze imiphumela engcono yokufudumeza. Uma unemibuzo mayelana ne I-Laser Welding Industrial Tube Rolling nokwakha umshini , sicela uxhumane Hangao (seko) neqembu lokuxhumana ngokushintshana nokubonisana.
