I-electrode yokushisela ye-E7028

I-AWS A5.1 E7028 Induku Yokushiselas

I-electorde yokushisela i-AWS A5.1 E7028 iyi-electrode yensimbi yekhabhoni embozwe nge-hydrogen-potassium-iron-powder ephansi. Impuphu yensimbi esembozweni ikhulisa izinga lokufakwa kwe-depositi kufika ku-180%. Inokusebenziseka okuhle kakhulu okwenza ukuthi ibe ne-arc ezinzile, i-spatter ephansi, ukususwa kwe-slag kulula futhi yenza ukushisela kwe-all-position. Insimbi efakwe i-depositi inezakhiwo ezinhle zemishini ezinikeza ukuqina okuhle kakhulu kwezinga lokushisa eliphansi.

Isicelo

I-AWS A5.1 E7028 isetshenziswa ekushiseni amafillet ayisicaba nayisicaba ezakhiweni ezenziwe ngensimbi yekhabhoni kanye nensimbi ephansi ye-alloy njengezinsimbi ze-16Mn, 09Mn2Si kanye ne-A, B, D, E ezisetshenziswa ekwakheni imikhumbi.

Izakhiwo Zemishini Zensimbi Egciniwe

Inkomba Yamanje (DC)

Amanothi:

1. I-electrode kumele ishiswe ekushiseni okungu-350°C ihora eli-1. Shisa induku noma nini lapho isetshenziswa.

2. Ukungcola okufana nokugqwala, amabala kawoyela kanye nomswakama kumele kususwe emsebenzini.

3. Kudingeka i-arc emfushane ukuze kwenziwe ukushisela. Indlela encane yokushisela iyathandwa.

Ukugcinwa nokubhaka kwe-E7028 Welding Electrode

Njengoba i-electrode ye-hydrogen ephansi, i-E7016 idingaukubhaka/ukomisangaphambi kokusebenzisa. Izinga lokushisa elinconywayo lokomisa noma lokubhaka lenduku ye-E7028 njengoba kuchazwe ku-AWS A5.1, Ithebula 1.3 lingu-500-800°F (260-425°C) ihora eli-1-2.

I-electrode ebhakiwe noma eyomisiwe kufanele igcinwe kuhhavini ophathwayo ekushiseni okungu-50-250°F (30-140°C) ngesikhathi sokusetshenziswa. Ama-electrode angasetshenziswanga kufanele abuyiselwe kumahhavini ahlala ekhona.
