I-AWS E9015-B9 I-Arc Welding Rod Stick Welding Electrodes Filler Metal Umfanekiso Obonakalayo
  • I-AWS E9015-B9 I-Arc Welding Rod Stick Welding Electrodes Filler Metal

I-AWS E9015-B9 I-Arc Welding Rod Stick Welding Electrodes Filler Metal

Inkcazo emfutshane:

I-R717 (AWS E9015-B9) yi-electrode yentsimbi engatshisi ubushushu ene-hydrogen sodium coating ephantsi equlethe i-9% Cr – 1% Mo-V-Nb.

R717                                                     

I-AWS A5.5 E9015-B9

Inkcazo: I-R717 yi-electrode yentsimbi engatshisi ubushushu ene-hydrogen sodium coating ephantsi equlethe i-9% Cr – 1% Mo-V-Nb. Sebenzisa i-DCEP (i-electrode yangoku ngqo) kwaye ingadityaniswa kuzo zonke iindawo. Ngenxa yokongezwa kwe-Nb encinci kunye ne-V, isinyithi esigciniweyo sinokumelana okuhle kakhulu nobushushu obuphezulu.

 

Ukusetyenziswa: Isetyenziselwa ukuwelda iityhubhu ezishushu kakhulu kunye neentloko zeebhoyila ezinobushushu obuphezulu kunye noxinzelelo oluphezulu, ezifana ne-A213-T91/A335-P1 (T/P91), i-A387Cr, i-91 kunye nezinye izakhiwo zentsimbi ezimelana nobushushu.

Isaziso:

1. I-electrode mayibhakwe iyure e-1 kwi-350℃ ngaphambi kokuba isebenze nge-welding;

2. Kubalulekile ukucoca umhlwa, isikali seoyile, amanzi, kunye nokungcola kwiindawo zokuwelda ngaphambi kokuba uwelda.

3. Fudumeza inxalenye ye-weld kwi-200 ~ 260°C ngaphambi kokuba uyi-welding, kwaye ugcine ubushushu obuhambelanayo phakathi kwe-interpass;

4. Pholisa kancinci ukuya kuma-80 ~ 100°C kangangeeyure ezi-2 emva kokuwelda; ukuba unyango lobushushu alunakwenziwa ngokukhawuleza, unyango lokukhupha i-hydrogenation lunokwenziwa kwi-350°CX iiyure ezi-2.
