Intonga yokuwelda yentsimbi yekhabhoni ye-E7018

Inkcazo emfutshane:

Iintambo zokuWelding AWS E7018 yi-electrode yentsimbi yekhabhoni egqunywe yi-hydrogen iron potassium powder ephantsi.


Iinkcukacha zeMveliso

Iithegi zeMveliso

Udidi:

I-AWS A5.1 E7018

I-ISO 2560-B-E4918A

I-GB/T 5117 E5018

Iintambo zokuWelding i-AWS E7018 yi-electrode yentsimbi yekhabhoni egqunywe yi-hydrogen iron potassium powder ephantsi. Uthuli lwentsimbi olukwi-coating lunyusa izinga lokufaka. Inokusebenziseka kakuhle kakhulu okuvumela ukuba ibe ne-arc ezinzileyo, ukuchitheka kancinci, ukususwa kwe-slag kulula kwaye idibanisa kuzo zonke iindawo. Isinyithi esigciniweyo sineempawu ezintle zoomatshini ezibonelela ngokuqina okuhle kakhulu kubushushu obuphantsi.

Intonga yokuwelda ye-AWS E7018 (i-electrode yohlobo lwe-powder yentsimbi esisiseko) ifanelekile ekuwelding intsimbi yekhabhoni kunye nesakhiwo sentsimbi esiphantsi kwe-alloy, njenge-Gr.50, njalo njalo.

Uhlolo lweX-ray Radiographic: IbangaⅠ

Indawo yokuWelda:

I-PA, i-PB, i-PC, i-PD, i-PE, i-PF

Amanqaku:
1. I-electrode mayifudunyezwe kubushushu obuyi-350°C kangangeyure e-1. Fudumeza intonga nanini na xa isetyenziswa.
2. Ukungcola okufana nomhlwa, amabala eoyile kunye nokufuma kufuneka kususwe kwindawo yokusebenza.
3. Kufuneka i-arc emfutshane ukuze kwenziwe i-welding. Indlela encinci yokuwelda iyathandwa.
