E6012 ielectrode inoshanda zvakanyanya inopa hunhu hwakanaka hwekubatanidza, kunyanya kune mashandisirwo asina kukwana zvakanaka.
E6012 ine arc yakanaka uye yakagadzikana uye inoshanda pamagetsi akakwira uye ine madonhwe mashoma. Ichishandiswa zvakasiyana-siyana, E6012 inogona kushandiswa nesimba reAC neDC.
Mashandisirwo Akajairika: midziyo yepurazi, kugadzirisa zvese, kugadzira michina, fenicha yesimbi, simbi yekushongedza, simbi yejira, matangi
Tsanangudzo yeAWS: AWS A5.1 E6012
Tsanangudzo yeJIS: D4312
Zvimwe Zvinotsanangurwa: DIN E4321 R3
I. ZVINOSHANDISWA:
Zvigadzirwa zvesimbi zvisina kusimba, Mahwindo esimbi nemidziyo yesimbi nemafenzi, simbi yemumagaba, kusonera mapaipi asina ngura, zvivakwa zvesimbi zvedzimba, zvigaro zvesimbi nematafura, maeredhi esimbi nedzimwe simbi dzisina kusimba nezvimwewo.
II. TSANANGURO:
Electrode yeShielded Metal Arc Welding inoshandiswa munzvimbo dzese ine hunhu hwakanaka hwekubatanidza uye kupinda mukati. Yakakodzera kuvhara mipata pamabasa asina kunaka ekugadzirisa. Inobata zviri nyore pasimbi diki pamwe chete nesimbi inorema. Weld ine mabhebhi akatsetseka, akatenderera zvakanaka uye akaenzana ane pamusoro wakakwenenzverwa. Fillets dzakakombama dzisingacheki zvakanyanya. Kushanda kwayo munzvimbo dzese, pamwe chete nesimbi yeweld inotonhora nekukurumidza uye arc ine simba kunoita kuti ive electrode yakakodzera mamiriro eworkshop nenzvimbo. Hunhu hwakanaka hwekuisa zvinhu pakugadzira zvese zvakamira uye zvakamira. Slag inobuda nyore nyore uye kazhinji inozvisunungura yega.
III. ZVINOKOSHA PAMUSORO PEKUSHANDISWA:
Chenjerera kuti usapfuure huwandu hwemafungu akakodzera. Kuwedera nemagetsi akawandisa hakungodzikisi kunaka kweX-ray chete, asiwo kunokonzera kuwedzera kwekupfapfaidza, kuchekwa zvisina kunaka uye kusakwana kwekufukidza kwetsvina.
Omesai maerekitirodhi pa70-100 degrees C kwemaminitsi 30-60 musati mashandisa. Kunyorova kwakanyanya kunoderedza kushandiswa uye kunogona kukonzera mamwe maburi.
Kuomesa zvakanyanya usati washandisa kunokonzera kuderera kwekupinda uye kupisa kwe electrode
