AWS A5.11 ENiCrFe-2 Nickel Based Welding Electrode Ni307-2 Low Hydrogen Nickel Welding Rod Arc Welding, Tyue Brand Welding Stick

I-Nickel ne-Nickel Alloy Welding Electrode

I-Ni307-2                                                     

I-GB/T EN6133

AWS A5.11I-ENiCrFe-2

Incazelo: I-Ni307-2 iyi-electrode esekwe ku-nickel ene-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode yamanje eqondile eqondile).Njengoba i-weld iqukethe inani elithile le-molybdenum, i-niobium nezinye izakhi ze-alloying, insimbi efakiwe inokumelana nokuqhekeka okuhle.

Isicelo: Isetshenziselwa ukushisela ama-alloys e-nickel-chromium-iron (afana ne-UNS N08800, UNS N06600), afaneleka ngokukhethekile ukushisela izinsimbi ezingafani, ukushisela ungqimba olushintshayo kanye nokushisela okungaphezulu, futhi ingasetshenziswa lapho izinga lokushisa elisebenzayo lingu-980 ° C, kodwa ingamelana ne-oxidation lapho izinga lokushisa lingaphezu kuka-820 ° C Ukuncipha kobulili nokuqina.

Ukwakheka kwamakhemikhali ensimbi ye-weld(%):

Izici zemishini ye-weld metal:

Okwamanje okunconyiwe:

Isaziso:

1. I-electrode kufanele ibhakwe ihora elingu-1 endaweni engaba ngu-300 ℃ ngaphambi kokusebenza kokushisela;

2. Kubalulekile ukuhlanza okugqwalile, uwoyela, amanzi, nokungcola ezingxenyeni zokushisela ngaphambi kokushisela.Zama ukusebenzisa i-arc emfushane ukushisela.
