Kana iwe wakamboedza 7075 aluminium bar welding, ungangoziva kuti haina kutwasuka sekushanda nemamwe maaluminium alloys. Inozivikanwa nekuda kwesimba rayo repamusoro uye yakanakisa kuneta kuramba, 7075 aruminiyamu isarudzo yakakurumbira mune aerospace, mota, uye yepamusoro-inoshanda engineering maapplication. Nekudaro, zvimiro zvayo zvakasarudzika zvinoita kuti zvizivikanwe zvakanyanya kunetsa weld. Saka nyanzvi dzinoita sei kuti dzive dzakachena, dzakasimba welds pane iyi alloy? Ngatiparadzei akakosha matipi uye matipi ekugona maitiro.
Nzwisisa Iyo Alloy Usati Warova Arc
Kiyi yekutanga yekubudirira mu7075 aluminium barwelding ndiko kunzwisisa kuumbwa kwealloy. 7075 isimbi inopisa-inopisa aluminium-zinc alloy iyo inowana simba rayo kubva mukuwedzerwa kwezingi, magnesium, uye mhangura. Nehurombo, izvi zvakare zvinoita kuti zviite zvakanyanya kutsemuka panguva uye mushure mekucheka. Kusiyana ne6061 kana mamwe maweld-friendly alloys, 7075 inowanzoita brittle intermetallic compounds izvo zvinogona kukanganisa weld kutendeseka.
Usati watombonhonga tochi, zvakakosha kuti utarise kuti welding ndiyo yakanakisa nzira yekujoinha here kana kuti dzimwe nzira dzakaita semechanicha yekusunga kana yekunamira bonding dzingaburitsa zvirinani.
Kugadzirira: Iyo Gamba Risingasungwe reKubudirira Welding
Mawelds makuru anotanga nguva refu isati yaitwa chaiyo welding process. Kugadzirira kwakakodzera kwakakosha kana uchishanda ne7075 aluminium. Tanga nekunyatsochenesa pasi kuti ubvise chero oxide layer, oiri, kana zvinosvibisa. Shandisa simbi isina Stainless waya bhurashi yakarongerwa aluminium chete uye tevera neacetone kudzikisa mafuta.
Joint design yakakosha zvakaenzana. Nekuti 7075 aluminium bar welding inotakura njodzi yakakura yekutsemuka, preheating simbi kusvika pakati pe300 ° F uye 400 ° F (149 ° C kusvika 204 ° C) inogona kubatsira kuderedza kupisa kwemagetsi uye kuderedza mukana wekushushikana-induced fractures.
Iyo Rudyi Filler Inoita Musiyano Wese
Imwe yesarudzo dzakanyanya kukosha muwelding 7075 aluminium kusarudza yakakodzera simbi yekuzadza. Nekuti 7075 pachayo haibatike nenzira yechinyakare, kushandisa yekuzadza iyo inonyanya kuenderana-inopindirana kunogona kuvhara gap. Sarudzo senge 5356 kana 4047 aluminium mafirita anowanzo kusarudzwa kuti avandudze ductility uye kuderedza kupaza munzvimbo yeweld.
Nekudaro, ramba uchifunga kuti kushandisa aya mafirita kunogona kuderedza zvishoma kusimba kwejoinhi kana ichienzaniswa neyakagadzika zvinhu. Ndiko tradeoff mainjiniya mazhinji anoda kuita kuti awedzere kusimba uye kuvimbika.
TIG kana MIG? Sarudza iyo Yakakodzera Welding Maitiro
Kune 7075 aluminium bar welding, TIG (Tungsten Inert Gasi) welding inowanzodiwa. Inobvumira kudzora zvirinani pamusoro pekuisa kupisa uye inogadzira yakachena, yakanyatsojeka welds-chaizvo izvo zvinodikanwa kana uchishanda nezvinhu zvinopisa zvakadaro.
Izvo zvakati, vagadziri vane ruzivo vachishandisa hunyanzvi hwepamberi uye michina inogona kubudirira MIG weld 7075 aluminium mune isinganyanyi kukosha maapplication. Zvisinei nemaitiro, kudzivirira kwakaringana ne100% argon gasi kwakakosha kuchengetedza dziva re weld kubva pakusvibiswa.
Post-Weld Heat Kurapa uye Kuongorora
Post-weld kupisa kurapwa kunogona kubatsira kuderedza kusara kunetseka uye kudzoreredza mamwe ma mechanic properties. Zvakadaro, kupisa-kupisa 7075 aruminiyamu kwakaoma uye kunofanirwa kuitwa nemazvo kudzivirira kukanganisa kana kuwedzera kutsemuka. Nzira dzisiri dzekuparadza dzekuyedza senge dhayi inopinda yekuongorora kana X-ray bvunzo inokurudzirwa kuve nechokwadi cheweld mhando.
Dzidzira, Kushivirira, uye Kururamisa
Welding 7075 aluminium bar muyedzo wehunyanzvi, moyo murefu, uye kugadzirira. Nepo maitiro acho asingarambiki achinyanya kudiwa kupfuura welding mamwe alloys, kutevera aya matipi enyanzvi kuchawedzera zvinoshamisa mikana yako yekuwana yakasimba, yakasimba majoini.
Kunyangwe iwe uri welder ane ruzivo kana kuti uchangotanga rwendo rwako neakakwirira-simba aruminiyamu alloys, kushandisa nzira dzakakodzera kunoita mutsauko wese.
Wagadzirira Kukwidziridza Mapurojekiti Ako Ekugadzira Metal?
Kuti uwane mamwe ruzivo rwehunyanzvi uye rutsigiro rwehunyanzvi pane aluminium kugadzirisa uye welding,Zvose Zvinofanira Chokwadiiri pano kuti ikubatsire iwe kuwana chaiyo uye kuita mupurojekiti yega yega. Bata nesu nhasi kuti udzidze zvakawanda!
