Yethula:
Emkhakheni wezimboni ohlale uvela, intuthuko kubuchwepheshe bokushisela idlala indima ebalulekile ekwandiseni umkhiqizo, ukusebenza kahle kanye nokunemba okuphelele. Njengoba isidingo sezindlela zokushisela ezinokwethenjelwa neziqinile siqhubeka nokwanda, ubuchwepheshe obusha obufana ne-Spiral Submerged Arc Welding (HSAW) buye baba abashintshi begeyimu. I-HSAW iyisimangaliso sobuchwepheshe esihlanganisa izinzuzo ze-arc engaphansi kwamanzi kanye ne-spiral welding futhi iguqula umhlaba wokushisela. Kule bhulogi, sizohlola umhlaba othakazelisayo we-spiral submerged arc welding kanye nokubaluleka kwakho ekuthuthukiseni ukusebenza kahle nokunemba kwezinqubo zokushisela ezimbonini.
Yini i-Spiral Submerged Arc Welding (HSAW)?
I-Spiral submerged arc welding (HSAW), eyaziwa nangokuthi i-spiral welding, iyindlela ekhethekile yokushisela esiza ukuhlanganisa amapayipi ensimbi amade, aqhubekayo. Indlela ihilela ukuphakela ipayipi lensimbi emshinini, lapho inhloko yokushisela eyindilinga ejikelezayo ngokuqhubekayo ikhipha i-arc kagesi, okwenza i-weld engenamthungo futhi engaguquki. Ikhanda le-welding lihamba ngokuzungeza ngaphakathi noma ngaphandle kwesiyingi sepayipi ukuze kuqinisekiswe ukufana nokuzinza kwenqubo yokushisela.
Thuthukisa ukusebenza kahle:
I-HSAW iletha izinzuzo eziningana enqubweni yokushisela, ekugcineni ikhulise ukusebenza kahle. Enye yezinzuzo ezibalulekile ze-HSAW yikhono layo lokushisela ipayipi lanoma yimuphi usayizi nogqinsi. Lokhu kuguquguquka kuvumela ukwanda kokwenziwa ngokwezifiso kanye nokuvumelana nezimo, okuvumela izimboni ukuthi zihlangabezane nezidingo ezahlukene zephrojekthi. Ukuqhubeka kwe-welding kuqeda isidingo sokuma njalo futhi kuqala, kunciphisa kakhulu isikhathi sokuphumula nokwandisa umkhiqizo. Ukwengeza, imvelo ezenzakalelayo yenqubo inciphisa ukuthembela emsebenzini wezandla, inciphisa ukwenzeka kwamaphutha, futhi yandise ukusebenza okuphelele.
Ukunemba kokuthuthukisa:
Ukunemba kuwuphawu lwayo yonke inqubo yokushisela eyimpumelelo, futhi i-HSAW iyahamba phambili kulokhu. Ukunyakaza okuvunguzayo kwekhanda le-welding kuqinisekisa iphrofayili ye-weld engaguquki phezu kwayo yonke i-circumference yepayipi. Lokhu kufana kuqeda ukuthi kungenzeka kube khona izindawo ezibuthakathaka noma okungahambi kahle ekushiseleni, kuqinisekisa ubuqotho besakhiwo nokuthembeka. Ngaphezu kwalokho, amasistimu okulawula athuthukile emishinini ye-HSAW angakwazi ukulungisa kahle imingcele yokushisela efana ne-arc voltage kanye nesivinini sokuphakelwa kocingo, okuholela ekushiseleni okunembile nokuphindaphindwayo. Lokhu kunemba kuthuthukisa ikhwalithi iyonke yejoyinti elishiselwe futhi kunciphisa amathuba okuba khona amaphutha noma ukwehluleka.
Izicelo ze-HSAW:
Izinzuzo ezingenakuqhathaniswa ze-HSAW zikwenza kube ubuchwepheshe obudumile bokushisela ezimbonini eziningi. I-HSAW isetshenziswa kabanzi ekwakhiweni kwamapayipi emkhakheni kawoyela negesi. Ama-welds athembekile ahlinzekwa yi-HSAW aqinisekisa ubuqotho nokuqina kwalawa mapayipi, okubalulekile ekuthuthweni okuphumelelayo kukawoyela negesi ezindaweni ezikude. Ukwengeza, i-HSAW inezicelo embonini yezokwakha, lapho isetshenziselwa khona ukukhiqiza izingxenye ezinkulu zesakhiwo sensimbi njengamakholomu nemishayo. Ukusebenza kahle okukhulu nokunemba okunikezwa yi-HSAW kuyenza ifaneleke kulawa maphrojekthi afunayo, ukunciphisa isikhathi sokwakha nokuqinisekisa ukuzinza kwesakhiwo.
Ekuphetheni:
Kafushane, i-spiral submerged arc welding (HSAW) ubuchwepheshe bokushisela obuphansi obuguqule izinqubo zokushisela ezimbonini. Ngokukwazi ukwandisa ukusebenza kahle nokunemba, i-HSAW isiphenduke impahla ebalulekile ezimbonini kusukela kuwoyela negesi kuya kwezokwakha. Imvelo eqhubekayo nezenzakalelayo yenqubo, ehambisana nesistimu yayo yokulawula enembile, iphumela ekushiseleni okuphumelelayo nokuthembekile. Njengoba ubuchwepheshe buqhubekela phambili, i-HSAW cishe izodlala indima ebaluleke kakhulu ekuhlangabezaneni nezidingo zomkhakha wezimboni wesimanje, iqinisekise amajoyinti ashiselwe aqinile.
