I-AWS E9015-B9 i-Arc-Resistant ye-Arc yokuWelding intonga ye-Welding Electrodes Filler Metal

Inkcazelo emfutshane:

I-R717 (AWS E9015-B9) i-electrode yensimbi ekwazi ukumelana nobushushu kunye ne-low-hydrogen coating sodium equkethe i-9% Cr - 1% Mo-V-Nb.

ngama-R717                                                     

AWS A5.5 E9015-B9

Inkcazo: I-R717 i-electrode yensimbi ekwazi ukumelana nokushisa kunye ne-low-hydrogen sodium coating equkethe i-9% Cr - 1% Mo-V-Nb.Sebenzisa i-DCEP (i-electrode echanekileyo yangoku) kwaye inokudityaniswa kuzo zonke izikhundla.Ngenxa yokongezwa kwexabiso elincinci le-Nb kunye ne-V, isinyithi esidipozithiweyo sinokuchasana nokunyuka kweqondo lokushisa eliphezulu.

 

Isicelo: Isetyenziselwa i-welding i-tubes superheated kunye neentloko ze-high-temperature kunye ne-high-pressure boilers, ezifana ne-A213-T91 / A335-P1 (T / P91), i-A387Cr, i-91 kunye nezinye izakhiwo zetsimbi ezinobushushu.

Isaziso:

1. I-electrode kufuneka ibhakwe ngeyure eli-1 kwi-350 ℃ ngaphambi kokusebenza kwe-welding;

2. Kubalulekile ukucoca umhlwa, isikali se-oyile, amanzi, kunye nokungcola kwiindawo zokuwelda phambi kokuba udibanise.

3. Ukufudumala inxalenye ye-weld kwi-200 ~ 260 ° C ngaphambi kwe-welding, kwaye ugcine ukushisa okuhambelanayo kwe-interpass;

4. Ukupholisa kancinci ukuya kwi-80 ~ 100 ° C kwiiyure ezi-2 emva kwe-welding;ukuba unyango olushushu alukwazi ukwenziwa ngokukhawuleza, unyango lwe-dehydrogenation lunokwenziwa kwi-350 ° CX ​​2h.
