- Applications
- Repairing of various kinds of cast iron produtcs.
- Characteristics
-
- - W-EST is a graphite type coated electrode, depositing weld metal consisting of pure iron.
- - It is designed for welding of cast iron when machining of the deposit is not required.
- - Hardness of the bonded area will be higher than that with nickel type electrode.
- Notes on Usage
-
- - Clean base metal before welding.
- - If there is a possibility that cracking spreads, make the stopholes at both ends of repairing part.
- - It is not necessary preheating and postheating in general but satisfactory results can be obtained by preheating at 100~200℃ in accordance with kind, shape and size of base metal.
- - Keep the weld metal length less than 50mm(2 inch) to disperse welding heat.
