Ma Electrode Othandizira Kuweta a AWS D507 Amavala Ndodo Zosagwira Ntchito Zoweta za Arc Welding

Kufotokozera Kwachidule:

Iyi ndi electrode yolumikizira yogwiritsidwa ntchito kwambiri yolumikizira zitsulo za kaboni kapena zitsulo za alloy ndi ma valve okhala ndi kutentha kogwira ntchito pansi pa 450 ° C.

GWIRITSANI NTCHITO:

Iyi ndi electrode yolumikizira yogwiritsidwa ntchito kwambiri yolumikizira zitsulo za kaboni kapena zitsulo za alloy ndi ma valve okhala ndi kutentha kogwira ntchito pansi pa 450 ° C.

CHITSULO CHOKHALA NDI MANKHWALA OMWE ANAKHALA (%):

	C	Cr	S	P	Zinthu zina za chiwerengero chonse
mtengo wa chitsimikizo	≤0.15	10.00 ~ 16.00	≤0.030	≤0.040	≤2.50
Mtengo wa chitsanzo	0.13	13.34	0.006	0.022	-

KULIMIRA KWA MISONKHANO YA PANSI:

(Kuzizira mpweya pambuyo powotcherera) HRC ≥ 40

MAWU OMWE AKUWONETSERA (DC + ):

M'mimba mwake wa ma elekitirodi (mm)	φ3.2	φ4.0	φ5.0
Kuwotcherera kwa magetsi (A)	80 ~ 120	120 ~ 160	160 ~ 200

KUSAMALITSA:

⒈ maelekitirodi olumikizirana a 300 ~ 350 ℃ ola limodzi lokha.

⒉ workpiece isanayambike kuwotcherera iyenera kutenthedwa mpaka madigiri 300 Celsius, pambuyo kuwotcherera, kutentha kosiyanasiyana kungathandize kuuma koyenera.

Ndodo Zowotcherera AWS E6010:

AWS E6010 ndi mtundu wa ma electrode olumikizirana a cellulose-Na, apadera a DC. Imagwiritsa ntchito ukadaulo wapamwamba wakunja, ili ndi ARC yozama, slags zochepa, yosavuta kuchotsa, yothandiza kwambiri pakulumikiza, komanso mawonekedwe okongola. Itha kugwiritsidwa ntchito pakulumikiza malo onse, kulumikiza malo oyima ndi otsika etc. imatha kufikira momwe mbali imodzi yolumikizira mbali zonse ziwiri imagwirira ntchito.

NTCHITO:

Ndodo zolumikizira AWS E6010 makamaka zolumikizira chitoliro chachitsulo cha kaboni kapena chinthu chomwecho, cholumikizira kumbuyo/chodzaza/cholumikizira chokongoletsera pansi pa kapangidwe kachitsulo.

CHENJEZO:

1. N'zosavuta kuziyika pamalo ouma, chonde sungani pamalo ouma.

2. Imafunika kutenthedwa ikasweka phukusi kapena ikalowa chinyezi, kutentha kwa kutentha kuyenera kukhala pakati pa 70C mpaka 80C, nthawi yotenthetsera iyenera kukhala kuyambira 0.5 mpaka ola limodzi.

3. Mukagwiritsa ntchito ma electrode olumikizira magetsi a 5.0mm, ndi bwino kugwiritsa ntchito mphamvu yamagetsi yamphamvu komanso yotsika, kuti muwongolere magwiridwe antchito a magetsi.
