Iinkqubo zokuWelda iipayipi zentsimbi ze-SSAW kwiintambo zegesi

Iinkqubo zokuWelda iipayipi zentsimbi ze-SSAW kwimigca yegesi Umfanekiso obonisiweyo

Inkcazo emfutshane:

Xa kufikwa ekufakweni kwemibhobho yegesi, ukuqinisekisa ukhuseleko kunye nokuthembeka kwenkqubo kubalulekile. Inkalo ephambili yale nkqubo yinkqubo yokuwelda esetyenziselwa ukudibanisa izinto ezahlukeneyo zombhobho wegesi, ingakumbi xa kusetyenziswa umbhobho wentsimbi we-SSAW. Kule blog, siza kujonga ukubaluleka kweenkqubo ezifanelekileyo zokuwelda imibhobho ekufakweni kwemibhobho yegesi kusetyenziswa umbhobho wentsimbi we-SSAW.

Iithegi zeMveliso

Umbhobho wentsimbi we-SSAW, eyaziwa ngokuba yipayipi efakwe i-arc welded engaphantsi komhlaba, isetyenziswa kakhulu ekufakweni kwemibhobho yegesi ngenxa yokuqina kwayo. Nangona kunjalo, ukusebenza kakuhle kwale mibhobho kuxhomekeke kakhulu kumgangatho weenkqubo zokuwelda ezisetyenziswa ngexesha lokufakelwa. Iindlela zokuwelda ezingafanelekanga zinokubangela ukuba amalungu abuthathaka nawonakele, nto leyo enokubangela iingozi zokhuseleko kunye nokusilela kwenkqubo.

Enye yezinto ezibalulekileyo ekuqinisekiseni ukuthembeka kofakelo lwepayipi yegesi kusetyenziswa umbhobho wentsimbi ofakwe i-spiral submerged arc kukukhetha inkqubo efanelekileyo yokuwelda. Oku kuquka ukuqwalaselwa ngononophelo kweendlela zokuwelda, izixhobo zokuzalisa kunye nokulungiswa kwangaphambili kokuwelda. Ukongeza, ukuthobela imigangatho nemigaqo yoshishino kubalulekile ukuqinisekisa ukuthembeka nokhuselekoumgca wegesisiinkqubo.

Ukulungiswa okufanelekileyo kwangaphambili kokuwelda kubalulekile ukuqinisekisa ukuwelda ngempumelelo kwemibhobho yentsimbi efakwe kwi-spiral submerged arc kwi-gas line. Oku kubandakanya ukucocwa ngokucokisekileyo kunye nokuhlolwa komphezulu wombhobho ukususa naziphi na izinto ezingcolisayo okanye iziphene ezinokuchaphazela umgangatho we-weld. Ukongeza, ukuze kufezekiswe i-weld eqinileyo nethembekileyo, umbhobho kufuneka ulinganiswe kwaye ulungelelaniswe ngokuchanekileyo.

isakhiwo esidityanisiweyo esenziwe ngokubandayo

Ngexesha lenkqubo yokufakelwa kwentsimbi, ingqalelo kwiinkcukacha kunye nokunamathela kwindlela echanekileyo kubalulekile. Ukukhetha indlela efanelekileyo yokufakelwa kwentsimbi, nokuba yi-TIG (i-tungsten inert gas welding), i-MIG (i-metal inert gas welding) okanye i-SMAW (i-stick arc welding), kufuneka kukhethwe ngokusekelwe kwiimfuno ezithile zokufakelwa kwepayipi yegesi. Ukongeza, ukusetyenziswa kwezinto zokugcwalisa ezikumgangatho ophezulu kunye neenkqubo zokufakelwa kwentsimbi ngononophelo kubalulekile ekuveliseni ii-welds ezinokuthenjwa nezihlala ixesha elide ezihlangabezana neemfuno zomsebenzi wepayipi yegesi.

Ukongeza, ukuhlolwa novavanyo emva kokuwelda ngamanyathelo abalulekileyo okuqinisekisa umgangatho wokuwelda kunye nokuthembeka kokufakelwa kwemibhobho yegesi kusetyenziswa umbhobho wentsimbi we-SSAW. Iindlela zovavanyo ezingonakalisiyo, ezinje ngovavanyo lwe-radiographic kunye novavanyo lwe-ultrasound, zinokunceda ekuchongeni naziphi na iziphene okanye ukungaqhubeki kwiindawo eziweldayo ukuze zilungiswe ngokukhawuleza kwaye ziqinisekise ukuthembeka kwenkqubo yakho yokuwelda.

Ngamafutshane, iinkqubo zokuwelda ezichanekileyo zibalulekile ekufakeni imigca yegesi kusetyenziswa iipayipi zentsimbi ezifakwe i-spiral submerged arc. Ukunyaniseka nokhuseleko lwenkqubo yakho yokuwelda igesi kuxhomekeke kumgangatho wokuwelda kwakho, ngoko ke kufuneka kulandelwe imigangatho yoshishino lokuwelda kunye neendlela ezilungileyo. Ngokubeka phambili ukulungiswa okufanelekileyo kokuwelda kwangaphambili, iindlela zokuwelda ezicokisekileyo, kunye nokuhlolwa okucokisekileyo emva kokuwelda, abafaki beepayipi zegesi banokuqinisekisa ukuthembeka nokhuseleko lokufakelwa kweepayipi zentsimbi ze-SSAW kwizicelo zeepayipi zegesi.
