Welding adagElectrode
Heerka: DIN 8555 (E9-UM-250-KR)
Nooca No.: TY-C65
Faahfaahin & Codsi:
· Electrode gaar ah oo leh alxanka ugu fiican iyo sifooyinka farsamada.
· Austenite- Ferrites biraha alxanka.Qiimaha xoogga sare iyo caabbinta dildilaaca sare.
Si gaar ah ugu habboon ku biirista biraha adag ee alxanka leh, marka la sameeyo dalabaadka ugu sarreeya ee alxanka.
Iska caabin sare oo dildilaac ah marka lagu biirayo biraha waalidka ee alxanka adag, sida biraha austenitic iyo ferritic steels, biraha manganese-sare leh ee birta daawaha ah iyo kuwa aan daawaynta ahayn, kulaylka lagu daweyn karo iyo biraha qalabka.Codsiyada hagaajinta iyo dayactirka qaybaha mashiinka iyo wadista iyo sidoo kale hagaajinta qalabka.
Sida lakabka barkinta ee alaabtan ayaa waliba ku habboon.

Tilmaamaha Guud:
Qaab-dhismeedka yar yar ee Austenite + Ferrite
· Mashiinka Wanaagsan
Horey u kululaynta qaybo ka mid ah gidaarada qaro weyn ilaa 150-150 ℃
Dib u habeynta 2 saacadood 150-200 ℃ ka hor inta aan la isticmaalin.
