Yethula:
Emkhakheni wezimboni ohlala ushintsha, intuthuko kwezobuchwepheshe bokushisela idlala indima ebalulekile ekwandiseni umkhiqizo, ukusebenza kahle kanye nokunemba okuphelele. Njengoba isidingo sezindlela zokushisela ezithembekile neziqinile siqhubeka nokukhula, ubuchwepheshe obusha obufana ne-Spiral Submerged Arc Welding (HSAW) sebushintshe kakhulu. I-HSAW iyisimangaliso sezobuchwepheshe esihlanganisa izinzuzo ze-submerged arc kanye ne-spiral welding futhi siguqula umhlaba wokushisela. Kule bhulogi, sizohlola umhlaba othakazelisayo wokushisela i-spiral submerged arc welding kanye nokubaluleka kwawo ekuthuthukiseni ukusebenza kahle kanye nokunemba kwezinqubo zokushisela zezimboni.
Kuyini i-Spiral Submerged Arc Welding (HSAW)?
Ukushisela i-arc engaphansi komhlaba okujikelezayo (i-HSAW), okwaziwa nangokuthi ukushisela okujikelezayo, kuyindlela ekhethekile yokushisela esiza ukuhlanganisa amapayipi ensimbi amade, aqhubekayo. Le ndlela ihilela ukufaka ipayipi lensimbi emshinini, lapho ikhanda lokushisela elijikelezayo elijikelezayo likhipha khona i-arc kagesi njalo, okudala ukushisela okungenamthungo nokungaguquguquki. Ikhanda lokushisela lihamba ngokuzungeza ngaphakathi noma ngaphandle kwepayipi ukuqinisekisa ukufana nokuzinza kwenqubo yokushisela.
Thuthukisa ukusebenza kahle:
I-HSAW iletha izinzuzo eziningana enqubweni yokushisela, ekugcineni ikhulisa ukusebenza kahle. Enye yezinzuzo ezibalulekile ze-HSAW yikhono layo lokushisela ipayipi cishe lanoma yiluphi usayizi nobukhulu. Lokhu kuguquguquka kuvumela ukwenziwa ngokwezifiso okukhulu kanye nokuzivumelanisa nezimo, okuvumela izimboni ukuthi zihlangabezane nezidingo ezahlukene zephrojekthi. Ukuqhubeka kokushisela kuqeda isidingo sokuma nokuqala njalo, kunciphisa kakhulu isikhathi sokungasebenzi futhi kwandise umkhiqizo. Ngaphezu kwalokho, uhlobo oluzenzakalelayo lwenqubo lunciphisa ukuthembela emsebenzini wezandla, kunciphisa ukwenzeka kwamaphutha, futhi kwandisa umkhiqizo ophelele.
Ukunemba kokuthuthukisa:
Ukunemba kuyisici esibalulekile sayo yonke inqubo yokushisela ephumelelayo, futhi i-HSAW iyaphumelela kulokhu. Ukunyakaza okujikelezayo kwekhanda lokushisela kuqinisekisa iphrofayili yokushisela ehambisanayo kuyo yonke indawo yepayipi. Lokhu kufana kususa amathuba okuba nezindawo ezibuthakathaka noma ukungalungi kushisela, okuqinisekisa ubuqotho besakhiwo nokuthembeka. Ngaphezu kwalokho, izinhlelo zokulawula ezithuthukisiwe emishinini ye-HSAW zingalungisa ngokunembile amapharamitha okushisela njenge-voltage ye-arc kanye nesivinini sokuphakelwa kwentambo, okuholela ekushiseni okunembile nokuphindaphindekayo. Lokhu kunemba kuthuthukisa ikhwalithi iyonke yejoyinti elishisiwe futhi kunciphisa amathuba okuba neziphambeko noma ukwehluleka.
Izicelo ze-HSAW:
Izinzuzo ezingenakuqhathaniswa ze-HSAW zenza kube ubuchwepheshe bokushisela obudumile ezimbonini eziningi. I-HSAW isetshenziswa kabanzi ekwakhiweni kwamapayipi emkhakheni kawoyela negesi. Ama-weld athembekile anikezwa yi-HSAW aqinisekisa ubuqotho nokuqina kwala mapayipi, okubalulekile ekuthuthweni kahle kukawoyela negesi emabangeni amade. Ngaphezu kwalokho, i-HSAW inezinhlelo zokusebenza embonini yokwakha, lapho isetshenziselwa khona ukukhiqiza izingxenye ezinkulu zesakhiwo sensimbi njengezinsika nezinsimbi. Ukusebenza kahle okukhulu nokunemba okunikezwa yi-HSAW kuyenza ifaneleke kakhulu kula maphrojekthi adinga amandla, kunciphisa isikhathi sokwakha nokuqinisekisa ukuzinza kwesakhiwo.
Ekuphetheni:
Ngamafuphi, ukushisela i-spiral submerged arc (HSAW) ubuchwepheshe bokushisela obushintsha izinqubo zokushisela zezimboni. Njengoba ikwazi ukwandisa ukusebenza kahle nokunemba, i-HSAW isibe yimpahla ebalulekile ezimbonini ezisukela ku-oyili negesi kuya ekwakheni. Uhlobo oluqhubekayo nolwenziwe ngokuzenzakalela lwenqubo, oluhambisana nohlelo lwayo lokulawula olunembile, luphumela ekushiseleni okusebenzayo nokwethembekile. Njengoba ubuchwepheshe buqhubeka phambili, i-HSAW cishe izodlala indima ebaluleke kakhulu ekuhlangabezaneni nezidingo zomkhakha wezimboni wanamuhla, iqinisekise ukuthi amalunga aqinile ashisele.
