High-ʻenehana argon kuʻihao

Ka 'ia paha o nā huahana ia i loko o ka hale, a ma ka hana, i na mea hiki ke hooheheeia, a me ko lakou oka. No kekahi mau nō a kiʻekiʻe-kbps paʻa pilina metala huahana maikaʻi ala - ke kuʻi nukeliu kuʻihao. I waena o nā kiʻina hana, kŘpa a nike, a leie aku e loaa ka maikai e like ai weld, argon kuʻihao hiki ke kapa. He Heʻano o ka piʻo kuʻihao. Hoʻokōʻia o ka piʻo e aa ana ma waena o ka ole-consumable (IeAUPIIe, IAa IO - tungsten)'ūholo uila, a me ka mea hiki ke hooheheeia workpiece. Ke'ūholo uila ua lele akula i loko o ka puhiʻino, a externally lako i ka mahele heheʻe i ka ciia o ka filler mea nei i kekahi hapa o ka pou huakai kaapuni. Nā kihi o ka waihona ipu metala, a me ka filler mea ua hoʻoheheʻeʻia ma ka wai koko piʻo a me ka hana i ka ulana. E weld punawai ma ke puhiʻino kīʻamo i loko o 'akomi ano ua lako i ka inert kinoea mea argon. Ua kokoke 'aʻole i komo i loko o Nine Inch AaOIeIOUIeXAOAaIN me ka metala i hoʻoheheʻeʻia, a me nā kinoea i hanaʻia i loko o ka piʻo ciia. Aie i ka mea i Ara i 38% kaumaha ia ma mua o ka ea ole, ka mea iho, pau ka lewapuni kinoea mai ka weld ciia, pela ka pale 'ia, a hikiʻole i ka hanana o mā ma ka welded ami. I ka ho'ēmi i weld porosity, hiki e hou i ka argon o 3-5% oxygen, alaila he mea hiki ke hooheheeia 'ohana ka palekana o kaila.

Argon kuʻihao hoʻolako i ka weld ho okumu ma ka inika mokulele hēkī a globular metala hoolilo. Globular hoolilo hualoaʻa i loko o ka lehulehu lakou hoopuehu, a hiki ole ia aliʻi e mea hānai kuʻihao kaʻina. ʻanoʻenehana ano i loaa mai ai ka wā keia ulana ka ino ma mua i loko o semiautomatic kuʻihao ma CO _2. Inkjet metala hoolilo hoʻolako argon kuʻihao i kuʻihao paialewa ma ke kamaʻilio au = 260A. Ma kēia kaʻina ke kuʻihao i ka pilina paʻa weld mea e like ai ua hou. Akā, i ke noi a ua kiʻekiʻe amperage pinepine hoʻopili like iʻanoʻenehana olelo o ke kaʻina hana (e laʻa me, unduly Kapikoowākea ka workpiece a me ka hoʻololi i nā waiwai o ka oka a ke hooheheeia). He nolaila, kupono e hoʻohana ka hoʻololiʻana mana na lako. Ua apono 'e OIeEOEIeAeEIIe, i ka mokulele hēkī o ka metala hoolilo mua paialewa kokoke loa kamaʻilio aʻu = 100A.

mea hō'ā kaʻa ka wā hoʻohana 'ana i' ole-consumable'ūholo uila lawe ia e kekahi kūikawā mea - he oscillator e pili ana ma ka laua me ka mana kumu. I ka wā o ka argon kuʻihao ua hana ma luna o alternatingʻikena, ma hope o mea hō'ā kaʻa o ka piʻo ua ua hō'ā i ka oscillator stabilizer pololei ia, e hanai ana oia i loko o ka piʻo ka lāʻau ikiʻai e hoʻololi i ka polarity. Kēia e hōʻoiaʻiʻo i ke kumupaʻa o ka piʻo.

Inā ka pili a eia i pono, ka cathode a me ka anode ia lŘlŘ haoʻa wela hoʻokuʻu (ma kahi o 70% - ma ka anode). Nolaila, steels, titanium oka a pau a me na mea hiki ke hooheheeia ma mua o Aluminum, hoʻohana pololei polarity e hoʻonui loa preform ua hehee. Al kuʻihao ua hana ma luna o ka alternating pono, e leie aku e luku mai i ka'okesaside ho film, me overheating ke huahana.

No ka kuʻihao māhele i ka kuhiliʻole steels, Aluminum a me kona oka a hiki no hoi ia e hoʻohana argon-piʻo kuʻihao me consumable'ūholo uila. Eia naʻe, kona laulā mea nunuiʻololī ma mua me ka tungsten nā uila aʻa lolo.

Ua Ua hoʻohana 'ia nā manuale a me ka' akomi argon kuʻihao. I waena o kona pono e loaʻa i ka hiki i ka paka i ka huina o nā huahana o ka poe liilii, mānoanoa me weld filler kumuhana, hana-ala komo ai i ka ili honua. Ka papa hana mea maikaʻi no ka kuʻihao luahi kulana o ka metalaʻohe. I hanaʻia ma ka weld mea maikaiʻanoʻenehana kiko'î. Argon piʻo kuʻihao - enehana, ka loa kupono i huiʻia no oka a steels, titanium oka a, Aluminum.

Aie i ka mea i pili pono io o ka hana, argon kuʻihao mau lima mea,ʻaʻole i loaʻa 'oihana welders wale no. Ma keia hihia, ma muli o ia ka mea uuku dala o ka hana, ole no laila, nui haʻahaʻa hana a ke kaʻina hana, a hoʻohaiki ana kona hoʻohana i ka nui-unahiʻole, i? Iecaianoaaiiuo.
