Notes on usage:

1. Dry the eåectrodes at 300-350℃ for 60 minutes and keep it at 100-150℃ before using.
2 To make the cooling time as short as possible between 500-800℃ to prevent the intergranular corrosion.
3. Clean up the contaminations on the base metal, groove and pass to pass with stainless steel brush.
4. Use smali heat input to reduce dilution, prevent cracking and improve impact value.
