Tsvimbo yekunamira yeE312 Inosangana nezvinodiwa neAWS E312-17 uye ndiyo mhinduro inosarudzwa yekubatanidza manual stick arc welding (SMAW) ine simba rakawanda uye yakasimba. Yakagadzirirwa kusanganisa manual stick arc welding, electrode inobudirira mumamiriro ezvinhu akaomarara ekugadzira nekugadzirisa nekuchinja kwenzira dzekusanganisa ma welding. Chinhu chikuru chakanakira kugona kwayo kugadzira austenitic deposit yakasimba, inodzivirira kutsemuka pamatombo akasiyana-siyana, kusanganisira simbi dzakasiyana-siyana, simbi dzakasiyana uye simbi dzine alloy grades, kunyanya mumamiriro ezvinhu apo kudzivirira kupisa kwakanyanya kukosha.
Maelectrode eE312 anoshandisa austenitic electrode deposit ine chromium yakawanda uye nickel yakawanda. Musanganiswa uyu unoipa simba rakanaka rekudzivirira kupisa, iro rinowanzo sangana nekupisa, dambudziko rinowanzoitika kana uchibatanidza majoini akamanikana, simbi dzakasiyana, kana simbi dzinopwanyika nyore nyore. Simbi inonyungudutswa inoratidza simba rakanaka rekudhonza patembiricha yemumba neyakakwira, uye ine ductility yakanaka uye kusimba kwemhedzisiro.
E312-17 yakasiyana nehunyanzvi hwayo hwekugadzirisa zvinhu.Tsvimbo yekunamira yeE312 (AWS E312-17) yakafanana neE312-16 electrode, asi kugadzirwa kwayo kwekufukidza kwakawedzera silicon uye kwakadzikira titanium. Kugadziriswa uku kwakanyatsonaka kunovandudza kugadzikana kwe arc munzvimbo dzese, kunyanya mu overhead fillet welds dzakaoma uye vertical up welds. Kemikari iyi inogadzira "jet arc" effect yakasiyana kana ikashandiswa mu horizontal fillet welds.
Elektrode yeE312 ine mashandisirwo akasiyana-siyana. Ndiyo inosarudzwa pakubatanidza simbi dzakasiyana, austenitic stainless steels necarbon kana low alloy steels, uye high nickel alloys nesimbi. Inoshanda zvikuru pakushandisa overlay ne cladding kana zvichidikanwa kuti isaparare uye isaparare. Elektrode iyi inoremekedzwawo zvikuru mukushongedza castings dzinoda kutsemuka. Maindasitiri makuru anovimba nekushanda kwayo anosanganisira kugadzira magetsi, kugadzira makemikari ne petrochemical, pulp nepepa, uye kugadzira nekuchengetedza michina mikuru.
Tsvimbo yekunamira yeE312 (AWS E312-17) inopa hunyanzvi hwakasiyana-siyana uye kuvimbika pamabasa ekushongedza anoda kuchinjika munzvimbo dzese, kuramba kutsemuka zvakanaka uye simba rakawanda. Kemikari yayo yekufukidza inopa mhedzisiro yakanaka ye "jet arc", iyo inogonesa kuchinjika kwakanaka kwefillet, ichipa welder hunhu huri nani hwekudzora uye kuisa hunhu. Simbi ye weld inobuda inodzivisa kutsemuka uye kudiridza kupisa, zvichiita kuti ive electrode yakakosha yekubatanidza kwakakosha senge simbi dzakasiyana, simbi dzine alloy yakawanda, uye mabasa akaoma ekugadzirisa.
