Nickel kanyeI-Nickel Alloy Welding Electrode

Ni307-4                                                     

I-GB/T ENi6093

I-AWS A5.11 ENCrFe-4

Incazelo: I-Ni307-4 iyi-electrode esekwe ku-nickel ene-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode yamanje eqondilepositive).Inokusebenza okuhle kakhulu kwe-welding enokuvutha kwe-arc okuzinzile, i-spatter encane, ukususa kalula i-slag,

kanye ne-weld enhle.

Isicelo:Isetshenziselwa ukushisela ama-alloys e-nickel-chromium-iron, njenge-Ni600, Ni800/800H nama-superalloys afanayo noma asekelwe ku-nickel anokushisa okusebenzayo okungu-900 ° C. Ingasetshenziselwa nezinsimbi ezinezinga lokushisa eliphansi eliqukethe I-Ni3% ~ 9%, njenge-ASTM A333, A334, A353, A522, I-welding ye-A553 ingasetshenziselwa ukushisela okungafani kwensimbi phakathi kwe-Mo400, Ni825, insimbi engagqwali nensimbi ephansi ye-alloy.

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.
