Titanium: titanium waldi (fasahar). Titanium waldi argon

A jirgin sama, Shipbuilding, kayan aiki, da kuma a wasu sauran masana'antu domin yi na hadaddun da m nodes amfani da tsada kayan kamar titanium. Yana da kyau ba kawai domin ta low nauyi, amma kuma da cewa da karfe ne ba batun lalata tafiyar matakai. Bari mu dauki wani kusa look at abin da daidai ne titanium. titanium waldi - yana da quite mai ban sha'awa topic magana game da wannan da za a tattauna.

A bit na janar bayanai

Just kai da kuma amfani da wani yanki na titanium samu rare. Sau da yawa shi ne pretreated. An fahimci cewa shi ne yawanci hõre waldi. Amma tun aiki karfe tana nufin baro, da masana da fuskantar matsalar lalata kayan a zazzabi na 400 digiri Celsius a ƙarƙashin rinjayar ruwa tururi, oxygen, da kuma nitrogen. By kanta, da tsari ne quite hadaddun, tun da shi wajibi ne don cika da manyan yawan fasaha da dokoki, da kuma wani irin waldi ya dace don aiki na karfe. A cikin wani hali, yau koya aiwatar titanium. titanium waldi ne da za'ayi ta hanyoyin da dama:

• electron masaƙa.
• Arc juyi.
• argon.

A halin yanzu rare ne duk hanyoyin, amma mafi tartsatsi argon waldi ga dalilai da dama, wanda za mu tattauna daga baya.

Titanium kuma ta gami

Active karfe rarraba a cikin yanayi isa. Mutane da yawa ce cewa shi ne bai isa ba, amma shi ke neman ya kwatanta. A cikin wani hali, da adadin titanium a cikin ɓawon burodi fi jan ko gubar. Wannan ne mai matukar m karfe. A m nau'i ya kai gare shi da ƙarfin 337 MPa, kuma a cikin gami da oda na 1 zuwa 250 MPa. Da narkewa batu na titanium - 1668 digiri Celsius.

A al'ada yanayin zafi, shi ne resistant zuwa lalata da kuma aiki a maƙiya yanayin. Duk da haka, a lokacin da zafin jiki da kai 400 digiri Celsius tuki halaye an plummeting. Yana reacts violently tare da nitrogen fara da za a oxidized ta oxygen da kuma ruwa tururi, wanda mai tsanani ya takaita ikon yinsa. Abin lura shi ne cewa abu ya yi ba yiwuwa ga zafi fatattaka a lokacin waldi, amma da hatsi zama ya fi girma, wanda impairs fasaha halaye na karfe da Weld quality. A ka'ida, mun fahimci wani abu kaɗan da cewa shi ne titanium. titanium waldi - a nan ne abin kuma shi ne mai ban sha'awa. Bari mu san kuma za mu yi magana.

Fasaha siffofin waldi

A yanzu lokaci ba za mu iya ce cewa titanium ne a rarity a cikin wannan, ko da samfurin. Yana yi aiki tare da shi mai yawa masana'antun daga daban-daban da masana'antu. Amma dole ne a fahimci cewa titanium - wani aiki sinadari. Wannan ya nuna cewa yin amfani da al'ada waldi unacceptable. Dalilin shi ne, a lokacin fall gurbatawa a cikin nau'i na carbides da nitrides wanda rage wasan kwaikwayon na kayan.

Saboda haka, asali sharadin waldi - cikakken kadaici daga kewaye yanayi. Wadannan su ne: oxygen, nitrogen, hydrogen da sauransu. Bugu da kari, da waldi aikin dole ne a da za'ayi a gwada high gudu. Tsawo dumama a cikin crystal raga yana faɗaɗa hatsi, wanda muhimmanci ƙara da brittleness. A cikin wani hali, waldi daga titanium, wanda za a tattauna a more daki-daki a kasa fasahar - hadaddun da kuma kalubale tsari. Kuma yanzu mu je kara.

Titanium waldi argon

Argon irin waldi wannan ƙarfe shi ne mafi shahara tsakanin kwararru a dukan duniya. Wannan shi ne saboda gaskiyar cewa akwai ba a amfani da fluxes da kuma wayoyin haka yi karin dabara da kuma hadadden waldi ayyukan. Bugu da ƙari, wata hanya domin samun argon welds da dangantaka da high quality-daban na waldi. Tare da fasaha na high quality-hatimi an samu.

Ba za mu iya ce game da universality na argon waldi. Shi ya ta'allaka ne da cewa akwai ikon rike duka biyu manyan Tsarin da kananan sassa. Kabu wannan bada wannan quality. Bugu da ƙari kuma, argon waldi na titanium ne mai kyau da cewa yana yiwuwa su yi aiki a kananan halin yanzu, da kuma shi damar zuwa Weld abu da ciwon kauri daga 0.5 mm. Argon iya mayar bayani rasa su na asali girma.

waldi na titanium kuma ta gami: Technology

Aikin dole ne a yi ta ƙwararren m tare da ya dace kayan aiki. Bugu da kari, wannan Multi-mataki tsari. All matakai dole ne ta jera dake da'awar kafa jerin kuma yi bisa ga matsayin.

A mataki na farko - fage. A wannan mataki shi wajibi ne don tsaftace karfe surface. Yana da muhimmanci a cire oxide fim. Gefuna yawanci bi oxyfuel Hanyar. Abu ko workpiece sarrafa shi da sunadarin flourine da wani acid (hydrochloric). Wannan ya kamata a samu wani m zafin jiki na 60 digiri Celsius. Ga shi yana da muhimmanci ga samar da kariya ga bi da karfe daga dauki tare da na yanayi iska biyu a waje da kuma daga raya gefe. Don wannan karshen, m jan karfe ko karfe gammaye cewa bukatar da za a amfani da kabu. Bugu da kari ga gammaye yarda da yin amfani da m visors da kuma musamman nozzles.

A lokacin da waldi tsari

A tsari faruwa a halin yanzu m. The kuka aka shigar na musamman tungsten lantarki. Lokacin da karfe zo a cikin lamba tare da lantarki baka kafa Weld pool. Zazzabi da shi sau da yawa ya kai 6 dubu digiri Celsius.

A karkashin matsin lamba na baka zubi titanium da ɗan tura. Sai dai itace cewa da kuka konewa a cikin lungu. Wannan za a iya dauke da wani amfani a matsayin muhimmanci inganta iya shiga iko. Bugu da ƙari kuma, kullum pumped argon, wanda ya samar da kariya da daukan hotuna zuwa oxygen, nitrogen da sauran gurɓatawa.

Wani abu kuma da

Game da bi da tare da titanium. Cold waldi shafi yin amfani da filler waya kawai a lokacin da karfe kauri ya wuce 1.5 mm. Idan kauri ne 10-15 mm, da waldi ne da za'ayi a wata kura idon baka nassi. Idan aikin da aka za'ayi tare da kiyaye fasahar, da kabu ba ya bukatar ya aiwatar daga slag. Yana zai zama mai santsi da kuma high quality. Irin wannan mahadi aka halin high airtightness da karko.

Arc waldi da electron katako waldi

Kura idon baka waldi ne mai gwada kwanan nan. The hanyar dogara ne a kan rufi abu daga waje yanayi na musamman fluxes. Juyi ne wani nau'i ne na manna. A mafi yawan amfani da Ant-A iri-iri na gyare-gyare. A peculiarity na hanyar kunshi a cikin cewa shi ne zai yiwu a cimma mafi crystal raga tsarin fiye da lokacin da waldi a wani inert yanayi. Saboda haka, an fi dacewa don haka bi da tare da titanium. Waldi titanium irin wannan hanya ba ya kaskantar da wasan kwaikwayon na ɓangare.

Electron katako waldi yana da yawa drawbacks. Amma akwai wani gagarumin amfani, wanda aka cikakken kariya daga waje yanayi na karfe. Wannan damar domin sosai high quality crystal raga. Lokacin da wannan tsari faruwa a high gudun, wajen rage yawan makamashi tsanani da aikin yi. Akwai kuma electro-slag waldi, wanda ya kwanan bai samu dace rarraba. Its fasalin kunshi a cewa wayoyin suna amfani da wannan abu a matsayin welded surface a cikin tsari.

ƙarshe

Yanzu kana da wani janar ra'ayin abin da waldi. Titanium inverter waldi ga wanda aka yadu amfani, yana da musamman halaye. Wannan shi ne dalilin da ya sa aka yi amfani da inda babu dace karfe ko wasu karafa. Amma babban kudin kayan aiki domin waldi, da makamashi tsanani da tsari, kazalika da yawa wasu korau dalilai ba su amfana wa ci gaban da yin amfani da wannan ƙarfe. Duk da haka, wasu kamfanoni suna kullum kokarin yi kamar yadda zai yiwu domin su sa shi sauki da kuma sauki don samun wani ingancin Weld. Alal misali, shugaban a tallace-tallace na Additives ne mai kauri "Elf Villingen" - "Titan". Cold waldi amfani da kamfanin zama wani hadadden da kuma dogon. Hakika, da rookie har yanzu ba zai iya jimre da irin wannan aiki, amma gwani zai zama sauƙin don su yi aiki. Amma, wannan shi ne duk da cewa za a iya gaya game da waldi wani karfe kamar titanium.
