I-AWS E8018-B2 Chromium Molybdenum Ukuwelda kwentsimbi enganyangekiyo nobushushu i-Electrode R306Fe Stick Electrodes Ukuwelda Izinto ezisetyenziswayo

Inkcazo emfutshane:

I-R306Fe (AWS E8018-B2) yi-electrode yentsimbi enganyangekiyo bubushushu ye-pearlitic enomgubo wesinyithi kunye nophahla oluphantsi lwe-hydrogen potassium oluqulethe i-1% Cr – 0.5% Mo.

I-AWS A5.5 E8018-B2

Inkcazo: I-R306Fe yi-electrode yentsimbi engatshiyo ubushushu ene-pearlitic powder kunye ne-hydrogen potassium type coating equlethe i-1% Cr – 0.5% Mo. Zombini i-AC kunye ne-DC zingasetyenziswa, kwaye zinokudityaniswa kuzo zonke iindawo ngokusetyenziswa okufutshane kwe-arc. Ubushushu bokudityaniswa kunye nobushushu phakathi kwe-interlayer yi-160 ~ 250 °C ngexesha lokudityaniswa.

Ukusetyenziswa: Isetyenziselwa ukuwelda intsimbi ye-1%Cr – 0.5%Mo enganyangekiyo kubushushu (njenge-15CrMo), njengemibhobho yokufudumeza yebhoyila enobushushu obusebenzayo obungaphantsi kwe-550°C, imibhobho yomphunga kunye neenqanawa zoxinzelelo ezinobushushu obusebenzayo obungaphantsi kwe-520°C, njl. Ingasetyenziselwa ukuwelda i-30CrMnSi steel castings.

Isaziso:

1. I-electrode mayibhakwe iyure e-1 malunga nama-350℃ ngaphambi kokuba isebenze nge-welding;

2. Kubalulekile ukucoca umhlwa, isikali seoyile, amanzi, kunye nokungcola kwiindawo zokuwelda ngaphambi kokuba uwelda.
