AWS E8018-B2 Chromium Molybdenum Ubushushu obunganyangekiyo kwintsimbi yeWelding Electrode R306Fe Stick Electrodes Welding Consumables

Inkcazelo emfutshane:

I-R306Fe (AWS E8018-B2) i-electrode yensimbi ye-pearlitic enganyangekiyo ukushisa kunye ne-iron powder kunye ne-low hydrogen potassium uhlobo lwengubo equkethe i-1% Cr - 0.5% Mo.

Inkcazo: I-R306Fe i-electrode yensimbi ye-pearlitic echasene nokushisa kunye ne-iron powder kunye ne-hydrogen ephantsi yohlobo lwe-coating equkethe i-1% Cr - 0.5% Mo. Bobabini i-AC kunye ne-DC ingasetyenziselwa, kwaye inokudityaniswa kuzo zonke izikhundla kunye nokusebenza okufutshane kwe-arc.I-preheating ye-weldment kunye nobushushu be-interlayer yi-160 ~ 250 °C ngexesha le-welding.

Isicelo: Isetyenziselwa ukuwelda kwe-1% Cr - 0.5% Mo pearlitic intsimbi ekwaziyo ukumelana nobushushu (efana ne-15CrMo), njengebhoyila yokufudumala imibhobho yomhlaba enobushushu obusebenzayo obungaphantsi kwe-550 ° C, imibhobho yomphunga kunye nemikhumbi yoxinzelelo enobushushu obusebenzayo obungaphantsi kwe-520 ° C. , njl. Ingasetyenziselwa i-welding ye-30CrMnSi castings yensimbi.

Isaziso:

1. I-electrode kufuneka ibhakwe ngeyure eli-1 malunga ne-350 ℃ ngaphambi kokusebenza kwe-welding;

2. Kubalulekile ukucoca umhlwa, isikali se-oyile, amanzi, kunye nokungcola kwiindawo zokuwelda phambi kokuba udibanise.
