I-AWS E10015-G Ukuqina Okuphezulu Okuphansi Kakhulu kwe-Hydrogen Electrode J707RH I-Low Alloy Steel Welding Rod

Incazelo emfushane:

I-J707RH (AWS E10015-G) iyi-electrode ye-hydrogen enamandla kakhulu futhi ephansi kakhulu enombozo we-sodium we-hydrogen ephansi

Incazelo: I-J707RH iyi-electrode ye-hydrogen enamandla kakhulu futhi ephansi kakhulu enombozo we-sodium we-hydrogen ephansi. Sebenzisa i-DCEP (i-electrode yamanje eqondile) futhi ingashintshwa kuzo zonke izikhundla. Ukusebenza kwenqubo yokushintshwa kuhle. Ukugoba okubandayo, ukumelana nokuqhekeka kanye nokumelana nokuqhuma kwamalunga ashintshwayo kuhle. Insimbi efakiwe inokuqina okuhle kanye nokuqina.

Ukusetshenziswa: Isetshenziselwa ukushisela izakhiwo ze-shell, futhi ifanelekela nokushisela izakhiwo ezibalulekile zensimbi enamandla aphezulu ye-Rp0.2≥590MPa.

Isaziso:

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

2. Kubalulekile ukuhlanza izikali zikawoyela, amanzi kanye nokungcola okugqwalile ezingxenyeni zokushisela ngaphambi kokushisela;

3. Sebenzisa umsebenzi omfushane we-arc lapho ushisela. Indlela encane yokushisela ifanelekile.
