I-AWS E10015-G High Toughness Ultra-Low Hydrogen Electrode J707RH I-Low Alloy Steel Welding Rod

I-Electrode ephansi ye-Alloy Steel Welding

I-J707RH                               

I-GB/T E7015-G

I-AWS E10015-G

Incazelo: I-J707RH iwukuqina okuphezulu kwe-hydrogen electrode ephansi ene-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode yamanje eqondile) futhi ingafakwa kuzo zonke izikhundla.Ukusebenza kwenqubo yokushisela kuhle.Ukugoba okubandayo, ukumelana nokuqhekeka kanye nokumelana nokuqhuma kwamalunga ashiselwe kuhle.Insimbi ediphozithi inepulasitiki enkulu nokuqina.

Isicelo: Isetshenziselwa ukushisela izakhiwo ze-hull, futhi ifanele ukushiselwa kwezakhiwo ezibalulekile ze-Rp0.2≥590MPa high-strength steel.

Ukwakheka kwamakhemikhali ensimbi ye-weld(%):

Izici zemishini ye-weld metal:

Okuqukethwe kwe-hydrogen yokusabalalisa kwensimbi efakiwe: ≤4.1mL/100g (i-mercury noma indlela ye-gas chromatography)

Ukuhlolwa kwe-X-ray: I grade

Okwamanje okunconyiwe:

Isaziso:

1. I-electrode kufanele ibhakwe amahora ama-2 ku-400 ℃ ngaphambi kokusebenza kokushisela;

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

3. Sebenzisa ukusebenza kwe-arc emfushane lapho ushisela.Ithrekhi yokushisela emincane ilungile.
