Insimbi yesakhiwo ekukhoneni kwayo odongeni, izinto ezinhle, ubuchwepheshe bokucubungula nokuzinza, iba yisinqumo sokuqala sephrojekthi enkulu yasekhaya neyangaphandle kawoyela negesi yamapayipi.Esikhathini esikhulu esiqondile se-seam esihlanganiswe ngepayipi lensimbi isakhiwo esihlangene, indawo ethintekile ye-weld kanye nokushisa iyindawo elula yokukhiqiza amaphutha ahlukahlukene, kanye ne-weld undercut, ama-pores, slag, ukuntuleka kokuhlangana, ukungabi khona kokungena, ukushisela, ukushisa, ukuqhekeka kwe-weld. iwuhlobo oluyinhloko lwezinkinga zokushisela, futhi ngokuvamile ziyimbangela yezingozi zekhwalithi yensimbi yesakhiwo.
Izinyathelo zokulawula ikhwalithi yensimbi yesakhiwo zihlanganisa:
Ngaphambi kokulawulwa kwekhwalithi yokushisela
1. Yenza ikhwalithi enhle yezinto zokusetshenziswa, ngemva kokudlula ukuhlolwa ngaphambi kokufakwa ngokusemthethweni endaweni yokwakha, futhi umise ngokuqinile ukusetshenziswa kwensimbi engekho ezingeni.
2, Kulandelwa ukuphathwa kwezinto zokushisela.Hlola ukuthi izinto zokushisela zemikhiqizo efanelekayo, isitoreji kanye nesistimu yokubhaka uma isetshenziswa, noma ukukhipha indawo ye-welding ihlanzekile futhi ayinakho ukugqwala, ukunamathela kwe-electrode kuqinile, kunomkhuhlane noma ngaphandle.
3, Ukuphathwa okuhlanzekile kwendawo yokushisela.Ikhwalithi ehlanzekile yokuhlola i-weld zone, ngaphandle kwamanzi, uwoyela, ukugqwala nokungcola ifilimu ye-oxide, okuwukuvimbela ukukhubazeka kwangaphandle kokukhiqiza indima ebalulekile.
4, Khetha indlela efanele yokufaka i-welding kufanele isetshenziswe ukuhlolwa kwe-welding yokuqala, emva kwezimiso zokushisela.
Ukulawulwa kwekhwalithi kunqubo yokushisela
1, Ngokwenqubo yokushisela imininingwane yocingo kanye nokubuyekezwa kwe-flux kulungile, vimbela ukusetshenziswa kabi kwentambo nokugeleza okubangelwa ingozi yekhwalithi yokushisela.
2, Ukugadwa kwemvelo yokushisela, thatha izinyathelo ezifanele ngemuva kokushisela lapho imvelo yokushisela ingezinhle (izinga lokushisa elingaphansi kuka-0℃, umswakama ohlobene mkhulu kuno-90%) kufanele ube.
3, Ngaphambi kokuhlolwa kokuqala okulindelekile kobukhulu begroove yokushisela, okuhlanganisa isikhala, umphetho ocashile, i-engeli nomlomo ongalungile, njll. ihlangabezana nezidingo zenqubo.
I-4, Ngaphakathi nangaphandle kwenqubo yokushisela ye-arc engaphansi kwamanzi ekhethiwe yamanje ye-welding, i-welding voltage, isivinini sokushisela neminye imingcele ilungile.
5. Ukuqondisa abasebenzi ekushiseleleni okungaphansi kwamanzi ngaphakathi nangaphandle kwe-arc yokushisela inzuzo egcwele yobude bepuleti leshubhu lensimbi, insimbi yomthungo eqondile iqinisa ukusebenza kahle kwe-arc yokushisela lapho amapuleti angaphakathi nangaphandle, esiza ukuthuthukisa ikhwalithi yokushisela ipayipi iphetha.
6, Gada abasebenzi be-welding ku-slag yokushisela ukuthi bahlanze kuqala, noma ngabe i-joint isicutshungulwe ngokuphelele, kungakhathaliseki ukuthi i-groove yamafutha, ukugqwala, i-slag, amanzi, upende nokunye ukungcola.
