Inkcazelo emfutshane:

Xa kuziwa kufakelo lombhobho werhasi, ukuqinisekisa ukhuseleko nokuthembeka kwenkqubo kubalulekile.Inkalo ephambili yenkqubo yinkqubo ye-welding esetyenziselwa ukujoyina amacandelo ahlukeneyo ombhobho wegesi, ngakumbi xa usebenzisa umbhobho wensimbi we-SSAW.Kule bhlog, siya kuhlolisisa ukubaluleka kweenkqubo ezifanelekileyo zokudibanisa umbhobho ekufakeni umbhobho wegesi usebenzisa umbhobho wensimbi we-SSAW.

Umbhobho wentsimbi we-SSAW, ekwaziwa ngokuba ngumbhobho odityanisiweyo we-arc, usetyenziswa ngokuqhelekileyo kufakelo lwemibhobho yerhasi ngenxa yokuqina kunye namandla.Nangona kunjalo, ukusebenza kwale mibhobho kuxhomekeke kakhulu kumgangatho weenkqubo ze-welding ezisetyenziswa ngexesha lofakelo.Ubuchule be-welding obungafanelekanga bunokubangela ukuba amalungu abuthathaka kwaye wonakaliswe, okukhokelela kwiingozi ezinokubakho zokhuseleko kunye nokungaphumeleli kwenkqubo.

Enye yezinto eziphambili ekuqinisekiseni ingqibelelo yofakelo lombhobho werhasi usebenzisa i-spiral submerged arc welded steel pipe kukukhethwa kwenkqubo yokuwelda efanelekileyo.Oku kubandakanya ukuqwalaselwa ngokucophelela kweendlela ze-welding, izinto zokuzalisa kunye nokulungiswa kwangaphambili kwe-weld.Ukongeza, ukuthotyelwa kwemigangatho yoshishino kunye nemimiselo kubalulekile ekuqinisekiseni ukuthembeka kunye nokhuseleko lweumgca wegesisiinkqubo.

Ulungiselelo olululo lwaphambi kokuwelda lubalulekile ukuqinisekisa ukuwelda okuyimpumelelo kwemibhobho yentsimbi edityanisiweyo ye-arc edityanisiweyo kufakelo lomzila wegesi.Oku kubandakanya ukucocwa ngokucokisekileyo kunye nokuhlolwa kwendawo yombhobho ukususa nayiphi na into engcolileyo okanye iziphene ezinokuchaphazela umgangatho we-weld.Ukongezelela, ukufezekisa i-weld enamandla kwaye inokwethenjelwa, umbhobho kufuneka ulinganiswe ngokuchanekileyo kwaye ulungelelaniswe.

Ngexesha lenkqubo ye-welding yokwenyani, ingqalelo kwiinkcukacha kunye nokubambelela kubuchule obuchanekileyo kubalulekile.Ukukhetha indlela ye-welding efanelekileyo, ingaba i-TIG (i-tungsten inert gas welding), i-MIG (i-metal inert gas welding) okanye i-SMAW (i-stick arc welding), kufuneka ikhethwe ngokusekelwe kwiimfuno ezithile zokufakelwa kombhobho wegesi.Ukongeza, ukusetyenziswa kwezixhobo zokuzalisa ezikumgangatho ophezulu kunye neenkqubo zokuwelda ngononophelo zibalulekile ekuveliseni iiwelds ezithembekileyo nezizinzileyo ezihlangabezana neemfuno zokusebenza kwemibhobho yegesi.

Ukongezelela, ukuhlolwa kwe-post-weld kunye nokuvavanya ngamanyathelo abalulekileyo okuqinisekisa umgangatho we-weld kunye nokuthembeka kufakelo lombhobho wegesi usebenzisa umbhobho wensimbi we-SSAW.Iindlela zovavanyo ezingonakalisi, ezinje ngovavanyo lweradiyographic kunye novavanyo lwe-ultrasonic, zinokunceda ekuchongeni naziphi na iziphene okanye ukungaqhubeki kumalungu adityanisiweyo ukuze alungiswe ngokukhawuleza kwaye aqinisekise ukuthembeka kwenkqubo yakho yombhobho werhasi.

Isishwankathelo, iinkqubo zokuwelda ezichanekileyo zibalulekile ekufakeni imigca yegesi usebenzisa i-spiral submerged arc welded steel pipes.Ukunyaniseka kunye nokhuseleko lwenkqubo yakho yombhobho wegesi kuxhomekeke kumgangatho we-welding yakho, ngoko ke imigangatho yoshishino lwe-welding kunye neendlela ezifanelekileyo kufuneka zilandelwe.Ngokubeka phambili ukulungiswa okufanelekileyo kwangaphambili kwe-weld, ubuchule bokuwelda ngokucokisekileyo, kunye nokuhlolwa ngokucokisekileyo emva kwe-weld, abafakeli bemibhobho yegesi banokuqinisekisa ukuthembeka kunye nokhuseleko lofakelo lwe-SSAW lwentsimbi yofakelo lwemibhobho yegesi.
