Kuwotcherera ndondomeko yachitsulo danga

1.Zofunika zamtundu wa danga la danga la mpira ndi zigawo za Bar chuma: Kutalika kosatha ndi zolakwika zowotcherera za chitoliro chachitsulo ndi bar zili mkati mwa ± 1mm Mpira wa Bolt: Sipayenera kukhala ming'alu pamtunda, cholakwika cha mtunda kuchokera pakati pa mpira kupita ku pamwamba pa dzenje wononga ndi mkati ± 10.2mm, ndi kupatuka ngodya dzenje wononga ndi ± 30′.Kuwotcherera kuyenera kuchitidwa molingana ndi GBJ97-81: kuwotcherera kwa zigawo kuyenera kukhala kwamphamvu yofanana, ndipo mawonekedwe awotcherera ayenera kuyendetsedwa mosamalitsa.Mpira uyenera kutenthedwa mpaka 50 ° musanawotchere ndi ma elekitirodi a 5016 kapena 5015.

2.Weld khalidwe kalasi: kugwirizana weld pakati pa mbale yothandizira, mpira wa bolt ndi gawo lophatikizidwa ndi mbale zonse zimatenthedwa, kalasi yabwino ndi 2, ndi zina zonse 3. Zojambula zomanga ziyenera kufika pamlingo wachiwiri.

3. Chitsulo chomwe chimagwiritsidwa ntchito muzitsulo zonyamula katundu chidzakhala ndi umboni wa mphamvu zowonongeka, kutambasula, mphamvu zokolola ndi sulfure ndi phosphorous, ndipo mawonekedwe opangidwa ndi welded adzakhalanso ndi umboni wa carbon content.Chitsulo chomwe chimagwiritsidwa ntchito popanga zida zonyamula katundu ndi zofunikira zosamangika zosamangika ziyeneranso kukhala ndi chitsimikizo choyezetsa kuzizira.

4.Kuyang'ana kwamtundu wa kuwotcherera kwa mafelemu amlengalenga kuyenera kukwaniritsa zofunikira zachiwiri zomwe zafotokozedwa mu <> (GB50205-2020).

5. Mulingo waubwino wa weld uyenera kutsatira mulingo wapano wa dziko "Code for Welding of Steel Structures" GB 50661 Njira yoyendera iyenera kutsatira mulingo wapano wa dziko "Code for Acceptance of Construction Quality of Steel Structure Engineering" GB 50205. Pakuti matako welds ndi makulidwe zosakwana 6mm, akupanga cholakwa kuzindikira singagwiritsidwe ntchito kudziwa weld khalidwe kalasi.6.Pamene chitoliro chachitsulo ndi mbale yosindikizira ndi mutu wa chulucho zimapanga ndodo, zowotcherera matako kumbali zonsezo zimakhala zolowera.

kuwotcherera:

Njira yowotcherera ndi njira yofunika kwambiri popanga danga lachitsulo, ndipo iyenera kuchitidwa motsatira malangizo ogwiritsira ntchito kuwotcherera.Chepetsani kupsinjika kotsalira komwe kumabwera chifukwa cha kuwotcherera, ndipo konzani mapindidwe munthawi yake pogwiritsa ntchito kutentha kwamoto.

A. Pamene chitoliro chachitsulo chikuwotchedwa ndi mbale yosindikizira ndi chitoliro chachitsulo, poyambira idzatsegulidwa malinga ndi zofunikira, ndipo ngodya ya groove idzakwaniritsa zofunikira za ngodya yomwe imapangidwa pakati pa electrode ndi groove pamwamba kuti asasokonezedwe ndi kusakanikirana. kuphatikizidwa kwa slag.Kuphatikiza apo, kusiyana kwa poyambira kuyenera kukhala Kwakukulu mokwanira kuti ma electrode arc athe kufika pansi pa poyambira ndikupewa kuya kosakwanira kolowera.
B. Pewani kuyika msoko wowotcherera pakati pa ndodo pamene chitoliro chachitsulo chatsekedwa.
C. Mfundo zofunika kuziganizira pa ntchito yowotcherera:
a.Pa kuwotcherera kwa arc pamanja, mawonekedwe otumizira sayenera kukhala akulu kwambiri, ndipo kuwotcherera kwamitundu yambiri ndi kusanjikiza kosiyanasiyana kumagwiritsidwa ntchito.
Panthawiyi, weld bead kapena interlayer kuwotcherera slag, slag kuphatikiza, okusayidi, etc. ayenera mosamalitsa kuchotsedwa.Kupukuta gudumu, chitsulo chingagwiritsidwe ntchito.
Zida monga maburashi a waya.
b.Msoko womwewo wowotcherera uyenera kuwotcherera mosalekeza ndikumalizidwa nthawi imodzi.
c.Kwa zolumikizira zosiyanasiyana zowotcherera, kuwotcherera kumalizidwa, slag ndi zitsulo zotayira pamwamba pa weld ziyenera kutsukidwa.
Yang'anani mawonekedwe a weld, ndipo pasakhale kukhumudwa, weld bead, undercut, blowhole, kusowa kwa kuphatikizika, ming'alu.
ndi zolakwika zina zilipo.
d.Pambuyo kuwotcherera matako ndi welded, akupanga chilema kudziwika pambuyo maola 24.
