I-AWS D507 I-Hardfacing Welding Electrodes Gqoka Izinduku Zokushisela Ezingazweli ze-Arc Welding Isithombe Esifakiwe

I-AWS D507 I-Hardfacing Welding Electrodes Gqoka Izinduku Zokushisela Eziqinile ze-Arc Welding

Incazelo emfushane:

Lena i-electrode yokushisela enemisebenzi eminingi yokushisela i-carbon steel noma i-alloy steel shafts namavalvu anezinga lokushisa elisebenzayo elingaphansi kuka-450 ° C.

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

SEBENZISA:

Lena i-electrode yokushisela enemisebenzi eminingi yokushisela i-carbon steel noma i-alloy steel shafts namavalvu anezinga lokushisa elisebenzayo elingaphansi kuka-450 ° C.

UKWAKHIWA KWEMETALI EDIPOSIWE (%):

	C	Cr	S	P	Ezinye izici zengqikithi
inani lesiqinisekiso	≤0.15	10.00 ~ 16.00	≤0.030	≤0.040	≤2.50
Inani lesibonelo	0.13	13.34	0.006	0.022	-

UBUNZIMA OKUSEKELELE:

(Kupholiswe umoya ngemva kokushisela) HRC ≥ 40

IREferensi NJENGAMANJE (DC + ):

Ububanzi be-Electrode (mm)	φ3.2	φ4.0	φ5.0
I-Welding current (A)	80 ~ 120	120 ~ 160	160 ~ 200

IZINYATHELO ZOKUZIVIKELA:

⒈ i-electrode yokushisela ibe ngu-300 ~ 350 ℃ ukubhaka 1h.

⒉ pre-welding the workpiece ukuba preheated kuya 300 ℃ ngenhla, emva Welding ukwelashwa ukushisa ezahlukene angathola ubulukhuni ezifanele.

IZINDIDI ZOKUSHISA AWS E6010:

I-AWS E6010 iwuhlobo lwama-electrode welding we-cellulose-Na, akhethekile ku-DC.Yamukela ubuchwepheshe obuthuthukisiwe bangaphandle, ine-ARC engena ngokujulile, ama-slags ambalwa, ukukhishwa kalula, ukusebenza kahle kwe-welding, izici zokusebenza ezinhle.Ingasetshenziselwa Welding for zonke isikhundla, mpo phezulu naphansi isikhundla Welding njll kungaba ukufinyelela umphumela ukuthi uhlangothi olulodwa Welding zombili izinhlangothi ukwakheka.

ISICELO:

Izinduku zokushisela i-AWS E6010 ikakhulukazi zokushisela ipayipi lensimbi yensimbi noma into efanayo, isekela i-weld / ukugcwalisa i-weld / i-cosmetic weld yesakhiwo sensimbi phansi.

QAPHELA:

1. Kulula ukuveza umswakama, sicela uyigcine esimweni esomile.

2. Idinga ukufudumeza lapho iphakheji iphuka noma umswakama udonswa, izinga lokushisa lokushisa kufanele libe phakathi kuka-70C kuya ku-80C, isikhathi sokushisa kufanele sisuke ku-0.5 kuya ku-1 ihora.

3. Uma usebenzisa ama-electrode wokushisela angu-5.0mm, kungcono ukusebenzisa i-high-thrust, low-current, ukuze uthuthukise ukusebenza kokushisela.
