Inqubo yokushisela yohlaka lwesikhala sensimbi

1.Izidingo zekhwalithi zohlaka lwesikhala sebhola elibholidi kanye nezingxenye Impahla yebha: Ubude obungavaliwe kanye nephutha lokushisela lepayipi lensimbi nebha kungaphakathi ±1mm Ibhola leBolt: Akufanele kube nemifantu phezulu, iphutha lebanga ukusuka enkabeni yebhola ukuya indawo engaphezulu yembobo yesikulufu ingaphakathi kuka-±10.2mm, futhi ukuchezuka kwe-engeli yembobo yesikulufu ngu-±30′.Ukushisela kufanele kwenziwe ngokuya nge-GBJ97-81: ukushisela izingxenye kufanele kube namandla alinganayo, futhi ikhwalithi yokushisela kufanele ilawulwe ngokuqinile.Ibhola kufanele ishiselwe ku-50 ° ngaphambi kokushisela ngama-electrode angu-5016 noma angu-5015.

I-2.Izinga lekhwalithi ye-Weld: uxhumano lwe-weld phakathi kwepuleti lokusekela, ibhola le-bolt kanye ne-embedded part plate yonke i-welded, izinga lekhwalithi liyi-2, kanti lonke liyi-3. Imidwebo yokwakha kufanele ifinyelele ezingeni lesibili.

3. Insimbi esetshenziswa esakhiweni esithwala umthwalo izoba nobufakazi bamandla aqinile, ukwelula, amandla okukhiqiza kanye nokuqukethwe kwesulfure ne-phosphorus, futhi isakhiwo esishiselwe kufanele sibe nobufakazi bokuqukethwe kwekhabhoni.Insimbi esetshenziselwa izakhiwo ezithwala imithwalo eshiselwe kanye nezakhiwo ezibalulekile ezingenalo i-welded ezithwala umthwalo kufanele futhi zibe nesiqinisekiso sokufaneleka sokuhlolwa kokugoba okubandayo.

4.Ukuhlolwa kwekhwalithi yomthungo wokushisela wamafreyimu esikhala kufanele kuhlangabezane nezidingo ezijwayelekile ezishiwo ku-<> (GB50205-2020).

5. Izinga lekhwalithi ye-weld lizothobelana nezinga likazwelonke lamanje “Ikhodi Yokushisela Izakhiwo Zensimbi” GB 50661 Indlela yokuhlola izothobela izinga lamanje likazwelonke “Ikhodi Yokwamukela Ikhwalithi Yokwakha Yobunjiniyela Besakhiwo Sensimbi” GB 50205. Kumashisela ezinqeni ezinogqinsi olungaphansi kuka-6mm, ukutholwa kwamaphutha nge-ultrasonic ngeke kusetshenziselwe ukunquma izinga lekhwalithi yokushisela.6.Lapho ipayipi lensimbi kanye nepuleti lokuvala kanye nekhanda lekhoni lakha induku, amashisela ezinqeni kuzo zombili iziphetho amashisela okungena agcwele.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

ukushisela:

Inqubo ye-welding iyinqubo ebalulekile ekukhiqizeni ifreyimu yesikhala sensimbi, futhi kufanele yenziwe ngokuhambisana ngokuqinile nemiyalelo yokusebenza kwe-welding.Nciphisa ingcindezi eyinsalela ebangelwa ukushisela, futhi ulungise ngesikhathi ukubola ngokushisa ilangabi.

A. Uma ipayipi lensimbi lishiselwe ngepuleti lokuvala kanye nepayipi lensimbi, i-groove izovulwa ngokuvumelana nezimfuneko, futhi i-engeli yomsele izohlangabezana nezimfuneko ze-engeli eyakhiwe phakathi kwe-electrode nendawo yomsele ukuze kugwenywe ukungafihli futhi. ukufakwa kwe-slag.Ngaphezu kwalokho, igebe le-groove kufanele libe likhulu ngokwanele ukuze i-arc ye-electrode ifinyelele phansi kwe-groove futhi igweme ukujula kokungena okwanele.
B. Gwema ukubeka umthungo wokushisela phakathi kwenduku lapho ipayipi lensimbi liqhunyiswa.
C. Izindaba ezidinga ukunakwa emsebenzini wokushisela:
a.Ngesikhathi sokushisela i-arc manual, uhla lokudlulisa akufanele lube lukhulu kakhulu, futhi i-multi-pass kanye ne-multi-layer welding isetshenziswa.
Ngesikhathi senqubo, i-weld bead noma i-interlayer welding slag, ukufakwa kwe-slag, i-oxide, njll. kufanele kususwe ngokuqinile.Isondo lokugaya, insimbi ingasetshenziswa.
Amathuluzi afana namabhulashi ocingo.
b.I-welding seam efanayo kufanele ihlanganiswe ngokuqhubekayo futhi iqedwe ngesikhathi esisodwa.
c.Emajoyini ahlukahlukene we-weld, ngemuva kokuqedwa kokufakwa kwe-welding, i-slag ne-spatter yensimbi ebusweni be-weld kufanele ihlanzwe.
Hlola izinga lokubukeka kwe-weld, futhi akumele kube khona ukucindezeleka, ubuhlalu be-weld, i-undercut, i-blowhole, ukuntuleka kwe-fusion, i-crack.
nezinye iziphambeko zikhona.
d.Ngemuva kokuthi i-butt weld ishiselwe, ukutholwa kwamaphutha nge-ultrasonic kufanele kwenziwe ngemuva kwamahora angama-24.
