Umhlahlandlela Ophelele Wezinduku Zokushisela Zensimbi Engagqwali: AF2209-16 (AWS E2209-16)

Uma ushisela insimbi engagqwali, ukusebenzisa i-electrode efanele kubalulekile ekufinyeleleni ukushisela okuqinile nokuhlala isikhathi eside.I-AF2209-16 (AWS E2209-16)iyi-electrode ethandwa kakhulu embonini yokushisela. Le electrode iyi-electrode yensimbi engagqwali ephindwe kabili ene-nitrogen ephansi kakhulu ene-calcium titanium coating, okwenza kube ukukhetha kokuqala kokusetshenziswa kokushisela.

I-electrode ye-AF2209-16 yenzelwe ukushisela insimbi engagqwali ye-duplex, eyaziwa ngokumelana kwayo okuhle kakhulu nokugqwala kanye namandla aphezulu. Ukwengezwa kwe-nitrogen ekwakhiweni kwe-electrode kusiza ukuthuthukisa ukumelana kwe-weld ekugqwaleni kwemigodi kanye ne-crevice, okwenza ifaneleke ukusetshenziswa ezindaweni ezinzima njengezimboni zokucubungula zasolwandle kanye namakhemikhali.

Esinye sezici ezibalulekile ze-electrode ye-AF2209-16 okuqukethwe kwayo kwekhabhoni okuphansi kakhulu, okusiza ukunciphisa ukwakheka kwama-carbide ensimbini yokushisela, ngaleyo ndlela kugcinwe ukumelana nokugqwala kwensimbi engagqwali. Ngaphezu kwalokho, i-calcium titanium coating ku-electrode inikeza izici ze-arc ezizinzile kanye nokususwa kwe-slag okulula, okuholela ekubeni i-weld bead ehlanzekile nebushelelezi.

Uma usebenzisa i-electrode ye-AF2209-16, kubalulekile ukulandela amapharamitha okushisela anconyiwe ukuze uthole imiphumela emihle kakhulu. Lokhu kufaka phakathi ukukhetha i-amperage efanele, i-voltage kanye nesivinini sokuhamba ngokusekelwe ekujikeni kwensimbi engagqwali ezoshiselwa. Ukwelashwa okufanele ngaphambi nangemva kokushiselwa, njengokushisa kwangaphambili kanye nokudlulisa amandla ngemva kokushiselwa, kufanele futhi kucatshangelwe ukuqinisekisa ubuqotho be-weld nokunciphisa ingozi yokugqwala.

Ngamafuphi, ama-electrode ensimbi engagqwali e-AF2209-16 (AWS E2209-16) ayisinqumo esithembekile sokushisela izinsimbi ezingagqwali ezimbili, enikeza ukumelana okuhle kakhulu nokugqwala, amandla aphezulu, kanye nokulula kokusetshenziswa. Ngokuqonda ukwakheka kwayo okuhlukile nokulandela imikhuba yokushisela enconyiwe, abashiseli bangafinyelela ukushisela kwekhwalithi ephezulu okuhlangabezana nezidingo eziqinile zezicelo ezahlukahlukene zezimboni. Kungakhathaliseki ukuthi kusetshenziselwa ukukhiqiza imikhumbi yokucindezela, amapayipi noma izingxenye zesakhiwo, i-electrode ye-AF2209-16 iyithuluzi elibalulekile lokufeza ukusebenza okuphezulu kokushisela ezisetshenzisweni zensimbi engagqwali.
