Ndodo ya ER385 Stainless Steel Welding Rod
Kufotokozera Kwachidule:
ER385 ndi mtundu wazitsulo zowotcherera, makamaka electrode yachitsulo chosapanga dzimbiri. Mawu akuti "ER" amaimira "Electrode kapena Rod," ndipo "385" akuwonetsa kapangidwe kake ndi mawonekedwe azitsulo zodzaza. Pachifukwa ichi, ER385 idapangidwira kuwotcherera zitsulo zosapanga dzimbiri za austenitic.
Ndodo Yowotcherera ya ER385:
Zitsulo zosapanga dzimbiri za Austenitic, monga Type 904L, zimakhala ndi chromium, faifi tambala, ndi molybdenum, zomwe zimawapangitsa kuti asachite dzimbiri komanso oyenera kugwiritsidwa ntchito m'malo ovuta. Ndodo zowotcherera za ER385 zimagwiritsidwa ntchito popanga zinthu zomwe kukana kwa dzimbiri ndi chinthu chofunikira kwambiri, monga m'mafakitale amafuta, petrochemical, ndi m'madzi am'madzi. Ndodo zowotcherera za ER385 ndizoyenera kutengera njira zosiyanasiyana zowotcherera, kuphatikiza kuwotcherera zitsulo zotetezedwa (SMAW), gas tungsten arc. kuwotcherera (GTAW kapena TIG), ndi kuwotcherera zitsulo zamagetsi (GMAW kapena MIG).

Chifukwa Chiyani Mutisankhe?
•Mutha kupeza zinthu zabwino kwambiri malinga ndi zomwe mukufuna pamtengo wotsika kwambiri.
•Timaperekanso Reworks, FOB, CFR, CIF, ndi mitengo yoperekera khomo ndi khomo. Tikukulangizani kuti mugwiritse ntchito zotumiza zomwe zingakhale zotsika mtengo.
•Zipangizo zomwe timapereka ndizotsimikizika kotheratu, kuyambira pa satifiketi yoyeserera ya zinthu zosaphika mpaka pachiwonetsero chomaliza. (Malipoti awonetsedwa pakufunika)
•Timatsimikizira kuti tipereka yankho mkati mwa 24hours (nthawi zambiri mu ola lomwelo)
•Perekani lipoti la SGS TUV.
•Ndife odzipereka kwathunthu kwa makasitomala athu. Ngati sizingatheke kukwaniritsa zomwe mukufuna mutapenda zonse zomwe mungasankhe, sitidzakusocheretsani popanga malonjezo abodza omwe angapangitse ubale wabwino ndi makasitomala.
•Perekani ntchito yoyimitsa kamodzi.

Kodi mawonekedwe a ER385 Welding Wire ndi ati?
1. Wabwino dzimbiri kukana, akhoza kukana dzimbiri yunifolomu wa sulfuric acid ndi asidi phosphoric, kukana dzimbiri asidi acetic pa kutentha kulikonse ndi ndende pansi pa kupsyinjika yachibadwa, ndipo angathe kuthetsa bwino pitting dzimbiri, pitting dzimbiri, mkangano dzimbiri, dzimbiri maganizo ndi mavuto ena a halidi.
2. Arc ndi yofewa komanso yokhazikika, yokhala ndi spatter yochepa, mawonekedwe okongola, kuchotsa bwino slag, kudyetsa waya wokhazikika, ndi ntchito yabwino yowotcherera.
Zowotcherera ndi zinthu zofunika:
1. Gwiritsani ntchito zotchinga zotchinga mphepo powotchera m'malo amphepo kuti musabowole chifukwa cha mphepo yamphamvu.
2. Kutentha pakati pa zodutsa kumayendetsedwa pa 16-100 ℃.
3. Chinyezi, madontho a dzimbiri ndi madontho amafuta pamwamba pa chitsulo choyambira ayenera kuchotsedwa kwathunthu asanawotchere.
4. Gwiritsani ntchito mpweya wa CO2 pakuwotcherera, chiyero chiyenera kukhala chachikulu kuposa 99.8%, ndipo kutuluka kwa mpweya kuyenera kuyendetsedwa pa 20-25L / min.
5. Kutalika kowuma kwa waya wowotcherera kuyenera kuyendetsedwa mkati mwa 15-25mm.
6. Mukamasula waya wowotcherera, chonde dziwani: tengani njira zotetezera chinyezi, zigwiritseni ntchito mwamsanga, ndipo musasiye waya wowotcherera wosagwiritsidwa ntchito powonekera mumlengalenga kwa nthawi yaitali.
