10: Electrode / Welding Wire Option
Welding wire should be chose the same or similar material as nature. Too large
difference in structure could lead to sand holes, air holes or even can be welded well. If the
welding hardness it too low, the welding part will be abraded or sloughed. If the welding
hardness is too high, the after processing is difficult or will rub the work pieces.
Work Pieces Type Available Electrode
Common plastic mold steel, hardness is
HRC25-35
H08Mn2SiA,P20
High-grade plastic mold steel, hardness is
HRC30-40
