AWS E9015-B9 Kuvala-Kulimbana ndi Arc Welding Ndodo Ndodo Yowotcherera Ma Electrodes Filler Metal

Kufotokozera Kwachidule:

R717 (AWS E9015-B9) ndi electrode yachitsulo yosagwira kutentha yokhala ndi mpweya wochepa wa hydrogen sodium wokhala ndi 9% Cr - 1% Mo-V-Nb.

R717                                                     

AWS A5.5 E9015-B9

Kufotokozera: R717 ndi electrode yachitsulo yosagwira kutentha yokhala ndi zokutira zochepa za hydrogen sodium zomwe zili ndi 9% Cr - 1% Mo-V-Nb.Gwiritsani ntchito DCEP (mwachindunji pakalipano ma elekitirodi abwino) ndipo mutha kuwotcherera m'malo onse.Chifukwa chowonjezera pang'ono Nb ndi V, chitsulo choyikidwacho chimakhala ndi kukana kutentha kwambiri.

 

Ntchito: Amagwiritsidwa ntchito kuwotcherera machubu otenthedwa kwambiri ndi mitu yamafuta otentha kwambiri komanso othamanga kwambiri, monga A213-T91/A335-P1 (T/P91), A387Cr, 91 ndi zida zina zachitsulo zosagwira kutentha.

2. Ndikofunikira kuyeretsa dzimbiri, sikelo yamafuta, madzi, ndi zonyansa pazigawo zowotcherera musanayambe kuwotcherera.

3. Yatsani gawo la weld pa 200 ~ 260 ° C musanayambe kuwotcherera, ndikusunga kutentha kofananako;

4. Kuzizira pang'onopang'ono mpaka 80 ~ 100 ° C kwa maola awiri mutatha kuwotcherera;ngati chithandizo cha kutentha sichingachitike mwamsanga, chithandizo cha dehydrogenation chikhoza kuchitidwa pa 350 ° CX ​​2h.
