I-GB/T E6016-B3

I-AWS A5.5 E9016-B3

Incazelo: I-R406 iyi-electrode yensimbi ekwazi ukumelana nokushisa i-pearlitic ene-low-hydrogen potassium coating equkethe u-2.5% Cr - 1% Mo.Both AC kanye ne-DC ingasetshenziswa, futhi ingashiswa kuzo zonke izikhundla.I-weldment kufanele ishiswe ngaphambili ibe ngu-160 ~ 200 ° C ngaphambi kokushisela.

Isicelo: Isetshenziselwa ukushisela izakhiwo zensimbi ezikwazi ukumelana nokushisa i-Cr2.5Mo pearlitic, njengamapayipi okushisa aphezulu kanye nokucindezela okuphezulu anamazinga okushisa okusebenza angaphansi kuka-550 ° C, imishini yamakhemikhali okwenziwa, kanye nemishini yokuqhekeka ye-petroleum.

Ukwakheka kwamakhemikhali ensimbi ye-weld(%):

Izici zemishini ye-weld metal:

Okuqukethwe kwe-hydrogen okusabalaliswa kwensimbi efakiwe: ≤4.0mL/100g (indlela ye-glycerin)

Ukuhlolwa kwe-X-ray: I grade

Okwamanje okunconyiwe:

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.
