Electrodes uamea uamea CB-A102
O le fa'ailo uamea uamea fa'aoga fa'amatalaga
.E masani ona faʻaaogaina i fale eletise, vailaʻau, suauʻu ma isi mea meafaigaluega.Chromium uamea stainless weldability le lelei, e tatau ona gauai atu i le faagasologa uelo, tulaga vevela vevela ma le filifiliga o electrode talafeagai.
2. CR-13 u'amea u'amea maualuga maaa pe a uma le uelo ma e faigofie ona maua ta'e.Afai o le ituaiga tutusa o le chromium stainless steel electrode (G202, G207) e faʻaaogaina mo le uʻamea, e tatau ona faʻamafanafanaina i luga aʻe o le 300 ° C ma faʻamafanafana pe a ma le 700 ° C pe a uma le uelo.Afai e le mafai ona faʻatautaia le faʻapipiʻiina o togafitiga vevela pe a maeʻa, ona filifili lea o le chromium-nickel stainless steel electrode (A107, A207).
3. Chromium 17 uʻamea uʻamea, ina ia faʻaleleia atili ai le faʻafefeteina ma le faʻamalosia ma faʻateleina le aofaʻi talafeagai o elemene mautu e pei o Ti, Nb, Mo, ma isi, e sili atu le lelei nai lo le chromium 13 uamea.A faʻaaogaina le ituaiga tutusa o le chromium stainless steel electrode (G302, G307), e tatau ona faʻamafanafanaina i luga aʻe o le 200 ° C ma faʻafefe i le 800 ° C pe a uma le faʻafefe.Afai e le mafai ona togafitia le vevela, ona filifili lea o le chromium-nickel stainless steel electrode (A107, A207).CR-NI uʻamea uʻamea electrode e lelei le corrosion teteʻe ma oxidation tetee, faʻaaoga lautele i vailaʻau vailaʻau, fetilaisa, suauu, gaosiga masini faafomai.
4. 0 ma lalo e mafai ona faʻaaogaina mo le faʻaogaina o tulaga uma.
5. 0 ma luga atu mo le uelo mafolafola ma fillet uelo.
6. Chromium-nickel uʻamea uʻamea uʻamea e iai ituaiga titanium-calcium ma le ituaiga hydrogen maualalo.Calcium titanate ituaiga e mafai ona faʻaaogaina i le AC ma le DC, ae o le faʻaogaina o le paʻu papaʻu AC, aʻo faigofie ona mumu, ina ia faʻaogaina le eletise DC.Diamita
7. E tatau ona faʻagogo le eletise, o le titanium-calcium type e tatau ona faʻagogo i le 150 ° C mo le 1 itula, ma le maualalo o le hydrogen e tatau ona faʻamago i le 200 ° C i le 250 ° C mo le 1 itula (leai se faʻagogo faifai pea, a le o lea. e faigofie ona ta'e le ufiufi ma pa'u ese), puipuia le suauu paʻu eletise pipii ma isi palapala, ina ia le faateleina ai le carbon anotusi o le uelo ma aafia ai le lelei o le uelo.
8. Ina ia puipuia le pala i le va o mata e mafua mai i le vevela, e le tatau ona tele naua le uelo, e itiiti ifo i le carbon steel electrode e uiga i le 20%, e le tatau ona umi tele le ARC, vave le malulu i le va o laulau, i le vaapiapi bead e talafeagai. .
