Aluminiyamu - welding kunye nomsebenzi kunye nezinto

Welding kwamalungu aluminiyam nobunzima yayo. Ngenxa conductivity ephakamileyo thermal kunye lobushushu yokunyibilika low size sinciphise amandla phezu ukufudumeza nga aluminiyam welding kufuneka iingxaki ezifana ukunyibilika iinxalenye nge welding, aqhumisele okanye ukuyilwa "nokuqhekeka eshushu."

aluminiyamu ezahlukeneyo aluminiyamu esekelwe, welding zinokuba nomahluko. I-aluminiyamu zithathwa non-weldable ukuba iinzame ezikhokelela nokuqhekeka eshushu. Kuba weldments ekhethiweyo compound deformable. Kwaye iSADC kakhulu ukuwelda kunye abanganyangekiyo aluminiyamu umhlwa azikho bubushushu-lukhuni, nangona amandla abo mechanical kuphantsi. Ubushushu-lukhuni, phezu koko, kuba amandla aphezulu kodwa welding phambili ngaphantsi ukumelana umhlwa.

Phambi kokuba kubekho iwelding, kucetyiswa ukuba ukufudumeza iwelding aluminiyam ngenxa yayo esezantsi-yokunyibilika kufuneka wenziwe ngokukhawuleza kakhulu.

Ukuze siphephe le iingxaki, kwiindawo macandelo aluminiyam kufuneka ngocoselelo icocwe phambi ukuwelda ukusuka ukufuma, neoli, ulwelo yokuqaba, njl, Xa ucoca kunye sijike. Kuyimfuneko ukuba ukucoca kumphezulu iinxalenye metal brush, zitshabalalisa oxide umboniso umaleko, nto leyo isale aluminiyam. Yi welding kufuneka wenziwe ngokukhawuleza emva nokucoca. Oku kuya kuqinisekisa umgangatho eliphezulu.

Ngenxa yezi mpawu kubalulekile ukukhumbula imithetho embalwa. Ekhaya - ekudaleni uyilo lwe-aluminiyam, kungcono ukuba asebenzise amalungu lempundu ze uzame ukufumana i welds kude ukusuka komnye ukuya Ukunqanda umngcipheko "neentanda ashushu."

Eyona kukhona iintlobo ukuwelda izakhiwo aluminiyam e Russia argon-arc indlela. Kodwa ke enasilela yokusebenza inverter welding.

Inverter - isizukulwana esitsha koomatshini. Kukho zombini iindlela zoshishino, ngokunjalo ukusetyenziswa ekhaya. Yena compact ngaphezu umatshini iwelding eqhelekileyo, ukusebenza phezulu-rhoqo ngoku, yaye akunyanzelekanga ukuba phezulu-power sombane. Ngenxa yeenzuzo inverter yayo welding ye-aluminiyam ngokubaluleka kuthandwa.

kubalulekile ukuba uthathe ingqalelo imali ekufuneka kwenziwe kwaye iinjongo zoshishino okanye indlu ngayo zithengwa kwi yokukhetha iwelding semi-oluzenzekelayo aluminium.

Ukuba inani elikhulu iimpawu ezongezelelweyo imodeli mveliso iya kuba nzima ukusebenzisa ukusetyenziswa ekhaya. Ukulungiselela le njongo, ilingane inverter elula uluhlu langoku amperes 140-180, ezi-okanye ontlantlu-ntathu, ngokuxhomekeke kwiimfuno.

Kuba yemveliso kuyimfuneko ukusebenzisa i ontlantlu-ntathu inverter 315 amperes. Banawo umthamo owaneleyo ukubonelela izakhiwo kokuxhuma phezu izixa ngomlinganiselo omkhulu.

Ukongeza, kuyimfuneko ukuba banikele ingqalelo nokupakishwa iimpawu ezongezelelweyo eziya kubonelela aluminium olomeleleyo. Welding akayi kuchaphazela iyahlala kwaye nokuthembeka. Ngoncedo izixhobo ezikumgangatho ophezulu, unako ukwakha izakhiwo ezahlukeneyo kunye nokuphumeza inkqubo elide yawo.
