AWS ENiCrFe-4 Nickel Alloy Welding Electrodes for Shielded Metal Arc Welding, Welding Rods

Nickel kunyeI-Nickel Alloy Welding Electrode

Ni307-4                                                     

GB/T ENi6093

AWS A5.11 ENCrFe-4

Inkcazo: I-Ni307-4 yi-electrode esekelwe kwi-nickel ene-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode yangoku ngqopositive).Inomsebenzi obalaseleyo we-welding kunye nokutsha kwe-arc okuzinzileyo, isitshizi esincinci, ukususa i-slag ngokulula,

kunye ne-weld entle.

Isicelo:Isetyenziselwa ukuwelda kwe-nickel-chromium-iron alloys, njenge-Ni600, i-Ni800 / 800H kunye ne-nickel-based superalloys kunye nobushushu obusebenzayo be-900 ° C. Inokusetyenziswa kwakhona kwiintsimbi ezinobushushu obuphantsi obuqulethe I-Ni3% ~ 9%, njenge-ASTM A333, A334, A353, A522, I-welding ye-A553 ingasetyenziselwa ukuwelda isinyithi esingafaniyo phakathi kwe-Mo400, i-Ni825, insimbi engenasici kunye nentsimbi ephantsi.

Ukwakhiwa kweekhemikhali zentsimbi edibeneyo(%):

Iimpawu zobuchwephesha bentsimbi ye-weld:

yangoku eCetyisiweyo:

Isaziso:

1. I-electrode kufuneka ibhakwe ngeyure enye malunga ne-300 ℃ phambi kokusebenza kwe-welding;

2. Kubalulekile ukucoca umhlwa, i-oyile, amanzi, nokungcola kwiindawo zokuwelda phambi kokuba udiye.Zama ukusebenzisa i-arc emfutshane ukuwelda.
