LSAW umbhobho wentsimbiligama lobuchwephesha le-Longitudinally Submerged Arc Welding.Inezi mpawu zilandelayo.Okokuqala, inkcazo yemveliso igubungela uluhlu olukhulu.Ayinakwenza kuphela imibhobho enobubanzi obuncinci kunye nobukhulu bodonga olukhulu kodwa kunye neemveliso ezinobukhulu obukhulu kunye nobukhulu bodonga olukhulu.Okwesibini, inamandla amakhulu okuthintela ukubola kunye nokuqhekeka.Inobukhulu obuchanekileyo obuphezulu kwaye ilungele ukwakhiwa kwe-welding kwisiza.Okwesithathu, ngenxa yenkqubo ye-welding emihle, inokuba nenkqubo ye-welding ezinzileyo kunye ne-welding ephezulu.Okokugqibela kodwa kuncinci, kulula ukuqonda ukubonwa kwempazamo engonakalisiyo kwinkqubo ye-welding.Ngenxa yolu ncedo kunye neempawu zayo ezikhethekileyo, umbhobho wentsimbi we-LSAW unethemba eliqaqambileyo kwaye abathengi abaninzi banqwenela ukuyamkela imisebenzi yemihla ngemihla.Ngokomgangatho we-API, kwimibhobho emikhulu yokuhanjiswa kweoli kunye negesi, umbhobho wensimbi odibeneyo kuphela ityhubhu echongiweyo xa ityhubhu ihamba kwindawo ye-alpine, ulwandle kunye neendawo ezihlala kwisixeko.

Ukususela ekuqalisweni okulula kombhobho wensimbi we-LSAW, inqaku liza kunika inkcazo ephathekayo malunga nethemba leemarike zemibhobho yensimbi ye-LSAW ekhaya nakwamanye amazwe.Ukuza kuthi ga ngoku, imarike yombhobho wentsimbi ye-LSAW iyanda kakhulu ngenxa yokwandiswa komthamo we-LSAW yaseTshayina.Phakathi kwabo bavelisi be-LSAW, abanye babo bakulungele ukuthenga imibhobho yokukhangela ukusuka ngasentshona ngelixa abanye abavelisi abahamba phambili bekhetha ukufumana umbhobho wokukhangela kubavelisi bezityalo basekhaya.Ngaphandle kweTshayina, iIndiya kunye noMbindi Mpuma nazo zinokwenyuka okucacileyo kumthamo weLSAW.I-China ibe yimimandla emikhulu yokuvelisa umbhobho wentsimbi we-LSAW.Ukungena kwi-2014, iimfuno ezingaphezulu kwipayipi yensimbi ye-LSAW kulindeleke.Makhe sithathe iTshayina njengomzekelo.Ukongeza kwiimfuno zangaphandle, i-China inemfuno enamandla yangaphakathi kulo mba wokwandiswa kobude bombhobho wegesi.

Ngapha koko, imfuno yombhobho wentsimbi ye-LSAW iqikelelwa ukuba iza kunyuka ngokuqhubekayo.Ngaphandle kwenyani, imarike yombhobho wentsimbi edityanisiweyo inokubandezeleka ngenxa yokubetha okukhulu.Ngaphambili, imarike yombhobho wentsimbi ye-LSAW ilawulwa ngabavelisi baseYurophu kunye namaJapan kodwa kwixesha elizayo, iya kuhlangabezana nokhuphiswano olunamandla oluvela eIndiya naseTshayina.Nangona kunjalo, nangona iChina inokuba ngowona mmandla mkhulu wokuvelisa umbhobho wentsimbi we-LSAW, iimfuno aziyi kuhambelana nomthamo.

Ukushwankathela, nangona umbhobho wensimbi we-LSAW unokubandezeleka ngenxa yeengxaki ezincinci kwinkqubo yophuhliso, isanandipha ithemba eliqaqambileyo nelinempilo ukusuka kwixesha elide.Bobabini abathengi kunye nabavelisi kufuneka baqiniseke ngethemba le-LSAW yensimbi yombhobho.
