Njengomthengisi ophambili kwimizi-mveliso, sinikezela ngesiqinisekisoI-Welding Electrode E2594(AWS A5.4 E2594-16), ebizwa ngokuba yi-AF2594-16. Le electrode yentsimbi engenasici egqunywe nge-titanium calcium, enomphezulu we-carbon duplex ibandakanya umxholo we-nitrogen obalulekileyo ukuze inike ukumelana nokugqwala okugqwesileyo. Ikhemikhali yayo ekhethekileyo ivelisa isinyithi esijijekileyo esinokuxhathisa kakhulu ukugqwala, ukuqhekeka kokugqwala okuxineneyo (SCC), kunye nokuqhekeka kobushushu.–kubaluleke kakhulu kwiindawo ezityebileyo ngekloridi ezifana nezityalo zokucubungula iikhemikhali kunye neziseko zophuhliso zaselwandle apho iintsimbi ezisemgangathweni ezingenasici zingasebenzi kakuhle.
I-electrode'Ukusebenza kakuhle kwayo kuvela kulwakhiwo lwayo olulawulwayo lwekhabhoni ephantsi (ngesiqhelo i-<0.03% C) idityaniswe ne-nitrogen kunye nokuphuculwa kwe-molybdenum. Oku kufezekisa uluhlu lwe-Pitting Resistance Equivalent (PRE) oluyi-2-40 ngelixa kugcinwa isakhiwo esilinganiselweyo se-austenite-ferrite. Uyilo lwe-metallurgical luthintela ukugqwala phakathi kwe-granular kwaye lugcina ukuqina kwempembelelo kuwo onke amaqondo obushushu ukusuka kwiimeko ze-cryogenic ukuya kwi-300°C (572)°F), idlula rhoqo iimfuno zoomatshini ze-AWS A5.4.
Ngomsebenzi, okuI-Welding Electrode E2594ine-titanium-calcium coating ephuculiweyo eqinisekisa uzinzo olugqwesileyo lwe-DC+ arc kunye nokususwa kwe-slag kuzo zonke izikhundla, kuquka ukusetyenziswa ngokuthe nkqo. I-coating inciphisa ukufunxwa kwe-hydrogen (<5ml/100g), isusa iingozi zokuqhekeka kwiindawo ezinoxinzelelo olukhulu. Ii-welders zixela ukudluliselwa kwesinyithi esithambileyo kunye nokuchitheka okuncinci kunye nokuphinda kube lula, okuphucula imveliso kwizicelo ezibalulekileyo ezifana nokuveliswa kwesitya soxinzelelo kunye nokuwelda kwepayipi.
Ukuqinisekiswa kokusebenza kuqinisekisa ikhemistri yesinyithi esinyibilikisiweyo esimalunga ne-25.5% Cr, 9.5% Ni, 3.8% Mo, kunye ne-0.22% N. Indlela ye-ASTM G48 ezimeleyo Uvavanyo lubonisa ukumelana nokugqwala okugqitha amanqanaba e-duplex eqhelekileyo ngama-40°C (104)°F). Ibhalansi yesigaba se-ferrite-austenite esilawulwayo se-45/55 inika amandla okuvelisa angama-650-750 MPa (94-109 ksi) kunye nobude obuyi-25%+–ukuhlangabezana nemigaqo ye-ASME, EN, kunye ne-NORSOK yeziseko zophuhliso ezibalulekileyo.
Kwizicelo zokugqwala ezifuna amandla,I-Welding Electrode E2594Ihlala iluphawu lomgangatho weshishini. Ukusebenza kwayo okuqinisekisiweyo kwiinkqubo zokususa ityuwa, amaqonga aselunxwemeni, kunye nee-reactors zamakhemikhali kuqinisekisa ukuthembeka. Ifumaneka kwiipakethi ezivaliweyo ze-vacuum eziyi-4kg ezinobomi beshelufu beenyanga ezingama-36, zonke izixhobo ziquka iziqinisekiso ezithile. Nxibelelana neqela lethu lobuchwephesha ukuze ufumane iinkcukacha zenkqubo yokuwelda ezihambelana nesicelo.
