Weld Tohu

He maha ngā tawhā e taea te āhuatanga e mekameka riro katoa:

• whanui - Ko te rahi o te tui i waenganui i nga rohe e kua unu aho Weld kitea;
• pakiaka Weld - te taha whakamuri tona i te mea i roto i te tawhiti mōrahi i te taha ki mua;
• whakaritea i roto i te wahi tino ohu nei o te tahi me te tohu i te tawhiti i te waka rererangi o te whakarewa turanga ki te rohe protrusion teitei - matakoma;
• piko - he hāngai tenei tohu, ki te te mea he wahi i roto i te Weld no, i roto i te meka, he he koha; takoto ana tēnei tawhā te i te wāhi i reira te tui kua te deflection rahi - e ia ki te rahi whenua whakarewa pereni whanganga kōpapatanga;
• cathetus tui - puta reira anake i roto i te kokonga, me te T-hononga; whanganga i roto i tenei ahua i te tawhiti iti i te mata taha o tetahi wahi mahi i te aroaro o te raina tui tauākī whakatīmata i runga i te mata tuarua.

Ngā momo o sutures i te tikanga o te mahi

• mekameka unilateral. E mahi ana ratou ki te kătahi whakarewa tonu me te roa katoa.
• hoahoa E rua-ara. E ai ki te hangarau i muri fehokotaki'anga unilateral, kua nekehia te pakiaka Weld, a muri anake whakamana i tenei fehokotaki'anga te ki atu te ringa.
• kaimono Takitahi-apa. whakamana fehokotaki'anga haere kotahi ki te heitiki Weld kotahi.
• kaimono Multilayer. Ratou whakamahi he mea pai, ka he matotoru nui o te whakarewa, i.e. ka ki te mahi i fehokotaki'anga i roto i te haere kotahi e kore e taea hoki te hangarau. Ka ngā Apa he tui o te maha awa (haere). Tenei ka whakawhāiti te horapa o te parae o pānga waiariki, me te whiwhi i te Weld mārō, me te-kounga teitei.

Momo o mekameka i runga i te tūranga mokowā me te roa

Te wehe taua tūranga fehokotaki'anga:

• raro tui ka paiherea kei roto i te manureva whakapae raro ie 0º koki whanaunga ki te whenua ..;
• te whakapae aronga fehokotaki'anga whakapae a taea te tapatoru hāngai i te tūemi i 0º ki 60º;

• Tuanui ka kawea te mahi i roto i i te koki 120-180º, e ko, e kei te mekameka i runga i te rangatira;
• "I roto i te poti", e pā ana e kai ki te kokonga T-hononga ranei anake, whakaturia te tūemi i te koki, ka kawea fehokotakianga te i roto i "i roto i te kokonga."

Ko te rärangi e roa:

• tonu, na rere reira tata katoa hononga, engari i reira he okotahi;
• tuinga taratahi, puta ratou anake i te hononga kokonga; Ka taea te kawea hononga më o tenei momo i roto i rua i roto i te whaikīngi me i te raupapa mekameka.

mata whakairo

E pā ana tēnei āhuatanga hoahoa i roto i te take i reira te matotoru o te whakarewa whakamahia mō te fehokotaki'anga, rahi neke atu i te 7 mm. Tapahi mata - he tango o whakarewa i te taha i roto i te tahi mau puka. whakamana ana tēnei tukanga te ka te fehokotaki'anga haere kotahi o hononga take. Ko te tika tenei i roto i te tikanga ki te tiki i te Weld tika. Ko rauemi matotoru, e hiahiatia ana whakairo te ki te tīmatanga rewa te haere pakiaka, me te ka heitiki muri mangai whakakī i te whewhe kōhao puta noa te matotoru o te whakarewa.

Ka taea te whakamana tapahi taha ki te he iti iho i te 3 mm te matotoru whakarewa. ka hua i roto i te wera-i roto i te mea o tona uara raro. āhuatanga whakairo e te tawhā whai hua: āputa - R; kokonga tapahi taha - α; pakeke, - ki. Ko te wāhi o enei tawhā whakaatu te tuhinga o te Weld.

faarahi Beveling te nui o Whakapau. Na reira, e tamata tenei uara ki te whakaiti. Kei te wehea te reira ki te maha ngā momo i te hoahoa:

• V-āhua;
• X-āhua;
• Y-āhua;
• U-āhua;
• kapiti.

Āhuatanga tapahi tapa

Kei te tikanga hoki thicknesses iti o te rauemi ki te kia paiherea i 3 ki te 25 mm whakamahia tapahi V-āhua-iu kotahi. kia whakamana te heretua i pito e rua ranei i tetahi o ratou. Metal 12-60 mm he mea tika ki te Weld ki rua bunching X-āhua taha. Ko te α koki i tapahi i te X, V āhua ko 60º, ki te whakamana i te heretua te i runga i tetahi anake mata, he rite ki te 50º te α uara. Hoki te matotoru 20-60 mm o e hei auau tino economical o whakarewa Weld ka tapahi U-āhua. kia hoki kia hanga e te heretua i runga i tetahi ranei e rua pito. Pakeke, kia 1-2 mm, a ka he rite ki te 2 mm te uara āputa. Hoki te matotoru whakarewa nui (i runga i 60 mm), wehia te ara whai hua tino e tapahi taha. Hoki te tahi paiherea ko te tino nui tenei tikanga, pānga reira e rave rahi āhuatanga hononga:

• tohu Houalotú. I te pūtahitanga o te rangatira ki te icon papa kia:

○ - tui kati;

┐ - mahi he tui o fehokotaki'anga te i roto i te tāutanga.

• Ti'araa o mekameka, ratou āhuatanga hanganga me te Hononga GOST.
• Ingoa paerewa he tui.
• Kakano ia tikanga rite ki paerewa ture.
• tohua huha, pā tenei kōwae anake ki te hononga koki.
• te whakamutu he tui o, ki te tetahi. Whakapūtāhia e tēnei te wāhi o te taahiraa me nga wāhanga fehokotakianga.
• ata atu uara pŭpŭ tauturu. A feruri ratou rite te tūemi motuhake.

iku'anga ngaahi houalotú

E tono ana hoki ēnei tohu i runga i te tihi o te papa, ki te te tui fehokotaki'anga kitea i roto i te tuhi, a raro reira, ka te kitea:

• Tango i te ngā Weld;
• maimoatanga mata me e whakarato he whakawhitinga maeneene ki te whakarewa turanga, whakakore sagging me te pāhiwihiwi;

• mata Weld mutu.

Ki te faaohie, ki te e hanga hononga hanga katoa i tetahi te āheinga, te whai i te taua tapahi hoahoa mata me ngā āhuatanga, tohu me ngā paerewa fehokotakianga tohua i roto i te ngā. pea nga hanganga katoa, engari he tokomaha nui o kaimono ōrite. Na ka wahia e ratou ki ngā rōpū, me te tautapa tau rangatū ki ia rōpū motuhake. I te hoê taime te tui ti'araa tonu. I te tahi atu hoatu he tau rangatū anake. kia tohua te maha o ngā rōpū, me te maha o tuinga i roto i ia o ratou i roto i te tuhinga paerewa.
