Zofunikira za Weld Maonekedwe a Pressure Pipe

Asanayambe kuyezetsa kwapaipi kwapaipi kosawonongeka, kuyang'ana kwa ma welds kumayenderana ndi zofunikira. Kupanikizika chitoliro kuwotcherera maonekedwe ndi pamwamba khalidwe la welded zimfundo zofunika ambiri ndi motere: kuwotcherera ayenera kuyang'ana bwino mawonekedwe, m'lifupi mbali iliyonse poyambira m'mphepete 2mm ataphimbidwa zoyenera. Fillet weld mwendo kutalika ayenera kukwaniritsa zofunika kapangidwe, mawonekedwe ayenera kukhala yosalala kusintha.

(1) Osalola ming'alu, kusowa kwa kuphatikizika, pores, slag, spatter.
(2) Kutentha kwapangidwe kumakhala pansi -29 madigiri mapaipi, zitsulo zosapanga dzimbiri ndi mipope yachitsulo yolimba yachitsulo imakhala yokulirapo, popanda kudulidwa. Zina zakuthupi zitoliro weld undercut kuya ayenera kukhala wamkulu kuposa 0.5mm, mosalekeza undercut kutalika sayenera upambana 100mm, ndipo mbali zonse za weld undercut nthawi zonse kukula mpaka 10 peresenti ya utali wonse wa weld.
(3) Osakhala pansi kuposa pamwamba pa weld pamwamba pa chitoliro. Weld kulimbitsa ndi zosapitirira 3mm, (pazipita m'lifupi mwa kuwotcherera mfundo pambuyo poyambira).
(4) Zolumikizira zowotcherera mbali yolakwika ya makulidwe a khoma ziyenera kukhala zosakwana 10% komanso zosaposa 2mm.
