Ama-electrode okushisela e-AWS D507 agqokwa izinduku zokushisela ezingamelani nokushisela ze-Arc Welding Isithombe Esivelele

Ama-electrode e-AWS D507 Hardfacing Welding agqokwa yizinduku zokushisela ezingamelani nokushisela ze-Arc Welding

Incazelo emfushane:

Lena i-electrode yokushisela eguquguqukayo yokushisela phezulu kwe-carbon steel noma i-alloy steel shafts nama-valve anezinga lokushisa lokusebenza elingaphansi kuka-450 ° C.

Sithumelele i-imeyili

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

SEBENZISA:

Lena i-electrode yokushisela eguquguqukayo yokushisela phezulu kwe-carbon steel noma i-alloy steel shafts nama-valve anezinga lokushisa lokusebenza elingaphansi kuka-450 ° C.

Umshini wokushisela (A)	80 ~ 120	120 ~ 160	160 ~ 200

IZINYATHELO ZOKUZIVIKELA:

I-electrode yokushisela engu-⒈ kufanele ibe ngu-300 ~ 350 ℃ yokubhaka ihora eli-1.

⒉ Ukushisela kusengaphambili i-workpiece kufanele ishiswe ku-300 ℃ ngenhla, ngemva kokushisela ukwelashwa okuhlukile kokushisa kungathola ubulukhuni obufanele.

IZINDONDO ZOKUSHINTSHA I-AWS E6010:

I-AWS E6010 uhlobo lwama-electrode okushisela ohlobo lwe-cellulose-Na, akhethekile e-DC. Isebenzisa ubuchwepheshe obuthuthukisiwe bangaphandle, ine-ARC engena ngokujulile, ama-slag ambalwa, kulula ukuhlukana, isebenza kahle kakhulu ekushiseleni, izakhiwo ezinhle zokusebenza. Ingasetshenziswa ekushiseleni kuzo zonke izindawo, ukushisela okuqondile phezulu naphansi njll. ingafinyelela umphumela wokushisela ohlangothini olulodwa ukwakheka kwezinhlangothi zombili.

ISICELO:

Izinduku zokushisela i-AWS E6010 ikakhulukazi zokushisela ipayipi lensimbi yekhabhoni noma into efanayo, ukushisela okusekelwe emuva/ukushisela kokugcwalisa/ukushisela kokuhlobisa phansi kwesakhiwo sensimbi.

QAPHELA:

1. Kulula ukuyiveza emswakama, sicela uyigcine isesimweni esomile.

2. Idinga ukufudunyezwa lapho iphakethe liphuka noma umswakama umuncwa, izinga lokushisa lokushisa kufanele libe phakathi kuka-70C kuya ku-80C, isikhathi sokushisa kufanele sibe kusukela ku-0.5 kuya ku-1 ihora.

3. Uma usebenzisa ama-electrode okushisela angu-5.0mm, kungcono ukusebenzisa amandla aphezulu, aphansi, ukuze uthuthukise ukusebenza kokushisela.
