Embonini yesimanje, ukusetshenziswa kwe2000W fibre laser welding imishiningoba ukushisela i-aluminium izinsimbi kuya ngokuya kwanda. Nokho, ukuze kuqinisekiswe izinga lokushisela nokuphepha, lezi zindaba ezibalulekile ezilandelayo zidinga ukuqashelwa.
1. Ukwelashwa kwendawo ngaphambi kokushisela
Ifilimu ye-oxide ebusweni bensimbi ye-aluminium ingaba nomthelela omubi kwikhwalithi yokushisela. Ukwelashwa okuphelele kwendawo kufanele kwenziwe ukuze kukhishwe ifilimu ye-oxide, amabala kawoyela nokunye ukungcola. Lapho inkampani ethile yezingxenye zezimoto ishisela uhlaka lwe-aluminium, ngenxa yokunganakwa kokwelashwa kwendawo, kwavela inani elikhulu lezimbotshana nemifantu endaweni yokushisela, futhi izinga lokufaneleka lehla kakhulu. Ngemva kokuthuthukisa inqubo yokwelapha, izinga lokufaneleka lenyuke laya ngaphezu kwama-95%.
2. Ukukhethwa Kwemingcele Efanelekile Ye-Welding
Imingcele yokushisela njengamandla e-laser, isivinini sokushisela kanye nesimo sokugxila kubaluleke kakhulu. Kumapuleti e-aluminium anobukhulu obungu-2 - 3mm, amandla angu-1500 - 1800W afaneleka kakhulu; kulabo abanobukhulu obungu-3 - 5mm, i-1800 - 2000W ifanelekile. Ijubane lokushisela kufanele lihambisane namandla. Isibonelo, uma amandla angu-1800W, isivinini se-5 - 7mm / s sifanelekile. Isikhundla sokugxila siphinde sithinte umphumela we-welding. Ukugxila kwamapuleti amancane kungaphezulu, kuyilapho amapuleti aminyene, adinga ukujula ngaphakathi.
3. Ukulawula Okokufaka Ukushisa
I-aluminium metal ine-conductivity ephezulu yokushisa futhi ijwayele ukulahlekelwa ukushisa, okuthinta ukungena kwe-weld namandla. Ukulawulwa okunembile kokufaka ukushisa kuyadingeka. Isibonelo, lapho ibhizinisi le-aerospace lishisela izingxenye ze-aluminium, ukulawula okungalungile kokufaka kokushisa kwaholela ekuhlanganisweni okungaphelele kwe-weld. Inkinga yaxazululwa ngemva kokuthuthukisa inqubo.
4. Ukusetshenziswa kwe-Shielding Gas
Igesi yokuvikela efanelekile ingavimbela i-weld oxidation kanye ne-porosity. I-Argon, i-helium noma izingxube zabo zivame ukusetshenziswa, futhi izinga lokugeleza kanye nesiqondiso sokushaywa kufanele kulungiswe kahle. Ucwaningo lubonisa ukuthi izinga lokugeleza kwe-argon lika-15 - 20 L/min kanye nesiqondiso esifanele sokushaywa kunganciphisa i-porosity.
Ngokuzayo, kulindeleke ukuthi kuvele imishini yokushisela ye-laser enamandla amakhulu futhi ehlakaniphe kakhulu, futhi izinqubo ezintsha zokushisela nezinto zokwakha nazo zizothuthukisa ukusetshenziswa kwayo okubanzi. Sengiphetha, ngokulandela lezi zinyathelo zokuphepha kuphela, ukuqongelela ulwazi nokuthuthukisa inqubo lapho izinzuzo zokushisela nge-laser zingase zibe neqhaza ekuthuthukisweni kwemboni yokukhiqiza.
