Description： Pearlitic heat-resisting steel with coating of low sodium hydrogen
electrode.Both AC/DC connection applicable for all position
welding.Workpiece shall be preheated about 150-300℃ before welding.
Application: WER207 Heat-resistant Steel Electrode apply to weld with working
temperature below 510℃.Such as pearlitic heat-resisting steel,steam
pipe and superheater pipe.
Chemical composition of Deposited metal(％):
Mechanical Performance of Deposited Metal(690±15℃×1H tempering)
※ X ray flaw detection requirement：LevelⅡ
Reference Current:(DC﹢or AC)
Notes:(Ⅰ)Please bake WER202 Heat-resistant Steel Electrode for 1
hour at about 150-200℃ before welding.(Ⅱ)Clean the surface to be
welded thoroughly to remove surface contaminations.
