Hē Weld: whakarōpū me rongoā

Fehokotaki'anga - tetahi o nga tukanga tino nui production. Ki reira, i hanga te hononga kei o mongamonga parahi i roto i te whakaaro tino momo. Ka rite ki i roto i te take o te tahi atu tukanga ahumahi, i ētahi wā i reira he he faaipoiporaa. e pā ana hē Weld raro reira, e taea matemate whakaiti i te kounga o te hua oti, ki te kore hanga reira mahi whakamate.

whakarōpū

E te ara, me pehea e taea e ratou te wehea? E wehea hē Weld katoa ki ngā rōpū matua e toru:

• Waho.
• Ā-.
• Koropiko ana.

hē waho Weld e maha te kāwai tino maha. Kei roto te reira i: rahi iti rawa, me te te displacement o te raina tahi, nodules rerekē, "motu", te na'ina'iraa anga me kore pūmau i roto i te tukanga o ngā piere o fehokotaki'anga, kapiti porosity ranei. pā ana hoki whanui Weld Nonuniform ki tenei momo. Kei te whakapono te reira e te hē waho o hononga paiherea ko te kāwai kino iti.

Nä, ngā te ā-kōputaputa, e kore e maha inclusions o para tino tunua wahi, me te kapiti i roto i te matotoru o te whakarewa Weld. Ki te whakaaro ki roto i mea kohakore, fistulas reira, whakawhānui i roto i te matotoru katoa o nga kapiti wahi, me te haki.

Ko te take matua o te kakano ia kohakore

• Tata tonu puta ratou ina ngana ana ki te whakamahi i ngā rauemi tino cheap me iti-kōeke.
• Ka taea e te taua te mea mo te kounga rawakore o te taputapu fehokotaki'anga. I tua atu, maha whakanuia ana te auau o te takanga o mea kohakore i muri i mea hanga rawakore whakamahia e te tohunga.
• O te akoranga, rawa maha puta tenei i roto i te hangarau disorders mahi.
• e kore e nohinohi hoki ngaio ngawari ki te tohu iti hē nui i roto i te tui Weld.

Ko reira ohie ki te matau e whiwhi i te hua tino-te kounga tiketike i roto i te take o te whakamahi o te taputapu tino aunoa. Kaua e wareware e pā ana ki te haratau o te mokowāmahi. Ko te kupu, Kei te tino maha kitea he tui patito nui, me te takahi o te whanui i roto i te wā i reira te welder (ara aravihi) mahi i roto i te tūranga fiemālie.

I roto i te meka, e kore kōpeka i roto i te whakaritenga mo te whakatinanatanga o te fehokotaki'anga i reira he tūemi e e ngā stipulate te oti whitiki te wāhi mahi, te whakarato ona hāneanea kounga.

tuhipoka nui

mohiotia pai Ahakoa he welders tauhou e ki te whakanui te kaha tui me whai i te iti taonga o te tikanga 1-2 mm o. I te wa ano maha whakaae te taua welders he hinga, ka hanga taonga 3-4 mm o. Fele, i roto i ngā take ohie, kahore he ki taua, engari e kore e ina tae mai te reira ki hua, kei tonu i roto i te āhua hihiri o te kawenga. arata'i tenei katoa ki kukū ahotea me te hua koi i roto i te tūponotanga o te naianei.

haira

Ka rite ki ta matou i kua mea, He tino kino hē i roto i mekameka me hononga. Ehara i te mea uaua ki te whakaaro he aha e tupu ki te e hei e ratou i roto i te kōrero, tikanga ki kia eke, hei tauira, i roto i te hanganga tautoko o te piriti rerewhenua. He tino kino i roto i te take o te kakano ia wahi i ratou he kowiri tira, ki te kia whakahaeretia i raro i ngā āhuatanga o huringa pāmahana taimau.

He haira nga tino mōrearea, rite he ratou he taiao "pūhiko" ngaohiko, ka e kia hāngai i roto i te Weld wahi paruparu. I tua atu, ratou tino whakaiti tona wāhanga mahi me te he pānga tino kino i runga i te kaha o te hononga.

Tikanga, e kore e enei hē waho i roto i mekameka i roto i te nuinga o te wā i te papaki. Ko e tika ana ki te meka e tonu e whai i te whakarewa (te tikanga) he faaipoiporaa iti-kōtaha, e taea arahi ki hopearaa rawa nui tenei.

Ka rite ki reira he undercuts?

Kei te whakaatu te take matua rawa nui o nāianei. I roto i ngā ki te pewa roa, whakarato tenei take tata kotahi rau ōrau tūponotanga o ratou tupu. I tua atu, i roto i ētahi wā, undercuts puta ka tere rawa pūtake whakawera displacement runga ake te mata whakarewa.

Ki te te hoahoa ahakoa te nui iti, he tino Kāore ara te kohakore iti rawa i roto i mekameka me pūhui o tenei momo. Papaki ratou te whakamahi i te tui fehokotaki'anga tau kikokore. Ki te reira he taua taipitopito pea ko reira pai ki te whakakapi tino (mōhio e pā parau whakamutunga ki hē katoa).

whakarewa rota undercooked

Ki te kei te teihana taua kei te tika i roto i te matotoru tui, ko reira tino mōrearea. Tuatahi, kitea he koha taua taea te whakamahi i anake te koha. Tuarua, kei te piki ano ratou i te taumahatanga tūturu i roto i te whakarewa. I roto i ngā ki te takahi o te hanganga ka paiherea, arata'i tenei katoa ki te mōrearea o kōrero kore taimi halá,. Rawa maha whakatika taua hē ā-i roto i mekameka i te take o te whakamahi i patu rino, me te taputapu fehokotaki'anga rawakore.

Porosity (ahakoa o tona wāhi) koi whakaiti āhuatanga kaha ki uara ore, arata'i ki "delamination" o te whakarewa, i.e. te kino o tona hanganga tūturu. Taipitopito ara ki porosity iti e rave rahi taime pea atu ki te wahi i raro i pikaunga noa i te timatanga o te mahi. He kōputaputa o hau tetahi he e kore e noa i te wā ki te haere atu i te apa maitai whakarewa.

Ka rite ki ki ngā momo katoa o hē Weld, e te tino maha whakatika ratou i roto i te take o electrodes raw iti-te kounga. Reira i tupu pinepine e whakatika ake te porosity no o te tahi mau poke i roto i te paruru hau. Ka rite ki i roto i te take o mua, kia hoki puta tenei momo o te koha i tere fehokotaki'anga rawa tiketike, ka takahia te tapatahi o te tiaki hau "pati" corny.

inclusions para

Inclusions o para nui pahuatia te taurite o te hanganga whakarewa. Ko te take matarohia o te hanganga - inadvertent mata tahi trimming i waikura, me te tauine toenga. Ko te tūponotanga o ratou tupu e whangai ana ki te kore ki te kahu Polovaisoa fehokotaki'anga o haurehu tiaki. tahuri Rare a tawhio noa āhua tohu kahore ati, hua i ratou kia haere OTC.

Kia mōhio e ki te whakamahia i roto i kakano ia i te kawehiko Tungsten, kia kitea ai te kōrero e matūriki whakarewa. Ratou tohu o te ati - rite i roto i te take o mua (arā, ko reira hē whakaaetia i roto i mekameka ..).

kapiti

He hake, me te roa whakawhānui e rua ki te tui, me te whakarewa me tata reira ranei. Ko ratou tino kino no te mea i roto i ētahi wā, te whakaiti i te kaha pūkaha o te hua, me te wiri ki tata te kore. Tei runga i te āhuatanga o te rauemi ki te kia paiherea, te kapiti e taea e rua pupuri i tona wāhi taketake, me te horapa ki te roa katoa o te workpiece i roto i te wa poto rawa.

Ehara i Koinei, ko te kohakore tino mōrearea i roto i mekameka tenei. Paerewa i roto i te nuinga o te wā e rapu makanga tonu o taua wāhanga, ahakoa o tona whakamahi tikanga (ki te haunga o ngā tūemi tino iti).

Non-taurite o te kaimono

Na ka karangatia e te reira rerekētanga kerekere o ngā tawhā āhuahanga o hononga e hiahiatia ana i roto i te āhuatanga ture. Mämä noa iho matou, ki te he fehokotakianga he "nakahi", obliquely me pera i runga i. N., tika te reira mai ki te momo rite o te koha.

Nuinga o ngā wā puta ratou i roto i te mahi o welders ngawari, me te ongo nui, taputapu hapa, me te hohoro banal. Dangerous tenei koha e te maha ngā ki undercooked, i te mea kua tawhiti atu kino. Ki te he iti te ine i te raina axial o te pūhui, me e kore e meinga whakaiti i roto i te kaha o te hua, ka taea te whakaaetia te wāhanga ki te whakahaere.

I roto i tenei take, mahara tonu kotahi mea ohie: te iti te koki o te whakawhitinga i te apa whakarewa turanga ki fusing, te kino te kaha pūkaha o te hua ka paiherea. O te akoranga, i roto i te hanga o te tahi mau waihanga whare (anga kōtuhi, hei tauira) i roto i ngā āhuatanga undervoltage ki te mahi i waho o te kaimono pāhiwihiwi mariko noa. Heoi, i roto i tenei take, ratou e kore e tohu tetahi mōrea ngā.

rongoā Basic, whakatikanga patu iro

Just mea te e whai ake nei: i roto i nuinga o te wā, e kore e te tukanga o te whakakorenga o mea kohakore o mekameka kōrero kia tikanga, kia rite ki i roto i te OTC atu iti iho ranei tino hua katoa ki etahi kohakore faaipoiporaa noa. Otiia i te tahi taime te reira tino i te take e kore he nui rawa te koha, engari no te mea e taea te whakakorea te reira. Me pēhea te ki te mahi i te reira?

I roto i pahuatia te take o te mata tarai ki hanganga maitai (wē-pewa fehokotaki'anga), āta horoia te wahi o te hononga i taka, a ka ngana anō. Ki te mea i reira e iti hē waho i roto i mekameka (pūhui pāhiwihiwi pāpaku poka), noa e taea te u ratou. O te akoranga, e kore e whiwhi i te reira wāhi, me te tango i apa whakarewa rawa nui.

Notice nui

A, no te haere mai te reira ki ngā hua o kowiri tira, e riro nei ki raro ki te maimoatanga wera obligatory, me whakamana te ako o hē i roto i te mekameka anake (!) I muri i te hararei i roto i te whānuitanga pāmahana i 450 ki te 650 ° C.

Te ako o te tahi atu momo

Ko te huarahi māmā ki te whakatika i sagging me te tahi aunoa pāhiwihiwi. I roto i tenei take, i te hononga tika horoia (rite kua matou whakahuatia kē). Kua mea matou ki runga ake e pā ana ki te undercuts iro,, engari kotahi ano mōhio tatou - ki taua hē taipitopito atu e tika ana ki te hōiho tonu te mea e taea e tona whakamahi e kino!

Ki te whai koe i te wera-i roto i (e kore, ko te rite noa nei), te whakakorenga o hē Weld noho rawa ohie: tuatahi, ka rite ki te mata ki te kia whakapai, a ka kohua i reira ano. Āhua pera te mahi ki ngā piere.

tikanga Basic "whakapaipai"

I whakakorenga o kohakore i ki te ū ki te etahi tikanga hangarau. Tuatahi, e hiahia ana koe ki te whai i te tikanga ohie: me ōrite te roa wahi hapa tona whanui me kia 10-20 mm kia mahue "tika i roto i te take".

Nui! e kore e nui te whanui o te tui fehokotaki'anga i muri i re provarkoy rua ona rahi i mua i tīmata mahi. Kaua e mangere ki te whakatika kohakore pai mata rite. Tuatahi, ārai reira para i tomo i te mongamonga whakarewa. I tua atu, ka āwhina i tenei mehua kinokore tere ake te mahi, me te whakapiki ake i te kounga o ona hua.

He mea tino nui ki te whakarite i tētahi tauira mō te-pūmau anō te wahi. Ki te kei te whakamahi koe LBM ( "Bulgarian"), he reira pai ki te tango i te puku o te diameter iti. Me nga mata taha o te tauira ki te mahi i nui taea maeneene, free o burrs atu wahi kohuki ranei i roto i te tukanga fehokotaki'anga taea tahuri ki te para taua katoa.

A, no te haere mai te reira ki pūhui konumohe, Titanium, me alloys o enei konganuku, te mea, ko te ki te whakatata atu kawenga. Tuatahi, kia whakamahia ai i roto i te pā ana ki mea kohakore i tenei take anake (!) Tikanga Mechanical, e kore e whakaaetia te whakamahi o te fehokotaki'anga pewa. Nuinga pai ki te tapahia ki raro te wāhanga pakaru, horoia me te re-māhī he tui.

He tuhipoka i runga i whakatikanga patu iro

Places papaki - re-brewed Me mamae ano pūhui te tukanga OTC. Ki te koha i roto i tetahi ranei tetahi tohu o te haumaru, he reira taea ki te ngana ki te fakatonutonu anō. Nui! Ko te nui o te ako, tei runga i te māka rino me ngā āhuatanga o te hua, engari i raro i ngā āhuatanga noa e kore e taea e koe te mahi anō i te mahi mo te neke atu i rua, e toru nga wa, rite te kore i reira he he heke koi i roto i ngā āhuatanga kaha kōrero.

Heoi kōrero e matou nga momo taketake o hē Weld.
