I-AWS E8018-B2 I-Chromium Molybdenum Engazweli Ukushisa Kwensimbi Electrode R306Fe Stick Electrodes Welding Consumables

Incazelo emfushane:

I-R306Fe (AWS E8018-B2) i-electrode yensimbi ekwazi ukumelana nokushisa i-pearlitic enempushana yensimbi kanye nohlobo oluphansi lwe-hydrogen potassium ehlanganisa u-1% Cr - 0.5% Mo.

I-GB/T E5518-B2

I-AWS A5.5 E8018-B2

Incazelo: I-R306Fe iyi-electrode yensimbi ekwazi ukumelana nokushisa i-pearlitic enempushana yensimbi kanye ne-hydrogen potassium ephansi yohlobo lwe-coating equkethe u-1% Cr - 0.5% Mo. Kokubili i-AC ne-DC ingasetshenziswa, futhi ingashiswa kuzo zonke izikhundla ngokusebenza okufushane kwe-arc.Ukushisa kwe-weldment kanye nokushisa kwe-interlayer kungu-160 ~ 250 ° C ngesikhathi sokushisela.

Isicelo: Isetshenziselwa ukushisela insimbi engu-1% Cr – 0.5% Mo pearlitic ukumelana nokushisa (efana ne-15CrMo), njengamapayipi angaphezulu okufudumeza kubhayela namazinga okushisa asebenzayo angaphansi kuka-550°C, amapayipi esitimu kanye nemikhumbi yokucindezela esebenza ngaphansi kuka-520°C. , njll. Ingasetshenziselwa ukushisela ama-castings ensimbi angu-30CrMnSi.

Isaziso:

1. I-electrode kufanele ibhakwe ihora elingu-1 endaweni engaba ngu-350 ℃ ngaphambi kokusebenza kokushisela;

2. Kubalulekile ukuhlanza okugqwalile, isikali sikawoyela, amanzi, nokungcola ezingxenyeni zokushisela ngaphambi kokushisela.
