I-J557SLA, J557SLB I-Low Hydrogen Welding Rod AWS E8015-G I-Low Alloy Stick Electrodes ye-Arc Welding

I-Electrode ephansi ye-Alloy Steel Welding

I-J557SLA, J557SLB                                        

I-GB/T E5515-G

I-AWS E8015-G

Incazelo: Lena i-sodium ye-hydrogen ephansi embozwe i-electrode ekhethekile yensimbi e-aluminium.Sebenzisa i-DCEP (i-electrode yamanje eqondile eqondile), futhi ingashiselwa kuzo zonke izikhundla ngokusebenza kwe-arc emfushane.I-J557SLA ingashiselwa ngokuqondile ngaphandle kokukhipha isendlalelo esi-aluminum endaweni eyi-groove ngaphambi kokushisela.Kodwa i-J557SLB kufanele isuse ungqimba olu-aluminum endaweni eyi-groove ngaphambi kokushisela.

Isicelo: Isetshenziselwa ukushisela isakhiwo sensimbi e-aluminum ngaphansi kwendawo yokugqwala ye-hydrogen sulfide, isulfure, i-ammonia, i-ammonium bicarbonate ne-hydrogen nitrogen enezinga lokushisa elisebenzayo elingaphansi kuka-540°C.Okufana namapayipi obhayela, izinto zokuhluza i-petroleum, okokusebenza kukamanyolo namapayipi esitimu, njll.

 Ukwakheka kwamakhemikhali ensimbi ye-weld(%):

 Izici zemishini ye-weld metal:

Okuqukethwe kwe-hydrogen ye-Diffusion yensimbi efakiwe: ≤6.0mL/100g (indlela ye-glycerin)

Ukuhlolwa kwe-X-ray: I grade

Okwamanje okunconyiwe:

Isaziso:

1. I-electrode kufanele ibhakwe ihora elingu-1 endaweni engaba ngu-350 ℃ ngaphambi kokusebenza kokushisela;

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