Izici Zobuchwepheshe Zentambo Yokushisela Ye-EM12K Ecmerged Arc

I-EM12K, evumelana nencazelo ye-AWS A5.17, imelela izinga elithile le-ucingo lokushisela lwe-arc olungaphansi kwamanziYenzelwe ukuhlanganiswa okuqinile kwezingxenye zensimbi yekhabhoni. Njengento ebalulekile esetshenziswayo enqubweni yokushisela i-arc engaphansi komhlaba, ukusebenza kwayo kuhlobene nokusetshenziswa ngasikhathi sinye kwe-flux ehambisanayo. Le ntambo yokushisela i-arc engaphansi komhlaba yenzelwe ukukhiqiza amadiphozithi okushisela ahambisanayo, aqinile futhi aqinile akwazi ukumelana nokucindezeleka okukhulu kokusebenza ezindaweni zezimboni ezidinga kakhulu.

Isici esichazayo sentambo yokushisela ye-arc engaphansi kwe-EM12K ukwakheka kwayo kwamakhemikhali ngamabomu. Le ntambo inokuqukethwe kwekhabhoni okuphezulu kakhulu uma kuqhathaniswa namanye amamaki ngaphakathi kwesigaba sayo. Ixutshwe ngamaphesenti aphezulu e-manganese ne-silicon, eklanyelwe ngqo ukudlula amazinga atholakala ebangeni lentambo ye-EL12. Lokhu kulinganisela okuqondile kwezakhi kubalulekile ekufezeni izakhiwo ezifiselekayo zemishini kanye nokuziphatha kwensimbi ku-weld eqediwe.

Ukwanda kwamazinga e-manganese ne-silicon kule ntambo yokushisela kuthuthukisa kakhulu amandla ayo okususa i-oxidation ngesikhathi sokushisela. Lesi yisici esibalulekile sobuchwepheshe, njengoba silwa ngenkuthalo nokwakheka kwama-porosity ngokususa i-oxygen echibini lokushisela elincibilikisiwe. Ukusetshenziswa kwalokhuucingo lokushisela lwe-arc olungaphansi kwamanziikhuthaza ukuqiniswa kwensimbi okunamandla kanye nobuqotho, okwenza kube ukukhetha okuthembekile kwezicelo lapho ukuhlanganiswa okuphelele kanye namadiphozithi angenamaphutha kuyimpoqo.

Insimbi ehlanganisiwe evela ku-wire EM12K ikhombisa ibhalansi enhle yamandla kanye nokuguquguquka, efanelekela izinqubo zokushisela ezisebenzisa ama-multi-pass. Lokhu kuyenza ibe yindawo ekahle yokusetshenziswa ekwakhiweni kwezakhiwo ezisindayo, imikhumbi yokucindezela, ama-ship hulls, kanye nezingxenye zesakhiwo ezithwalwa imithwalo ephezulu. Ukusebenza kwayo okuqhubekayo kuqinisekisa ukuthi amalunga ahlanganisiwe agcina ubuqotho bawo isikhathi eside, ngisho nangaphansi kwezimo zesevisi eziyinselele ezihilela ukudlidliza noma ukucindezeleka.

I-EM12Kucingo lokushisela lwe-arc olungaphansi kwamanziiyithuluzi elikhethekile elisebenzisekayo elenzelwe ukusetshenziswa kwensimbi yekhabhoni ebalulekile. Iphrofayili yalo ehlukile yamakhemikhali, ebonakala ngekhabhoni ephezulu, i-manganese, ne-silicon, inikeza i-deoxidation ethuthukisiwe kanye nezakhiwo zemishini ezinokwethenjelwa esimweni esishiselwe. Ukunamathela kumazinga e-AWS A5.17 kuqinisekisa ikhwalithi yayo eqhubekayo, okwenza lolu cingo lube yisisombululo esizwakalayo kwezimboni ezidinga ukuxhumana okushiselwe okuhlala isikhathi eside nokusebenza kahle.
