DETAILS
It is used for the welding of all types of cast irons.
Features
- It gives a minimum amount of spatter and a very stable arc. The slag is easy to remove.
- Heat effected zone is very narrow. Porosity free weld metal can be easily machined. Filler metal has the same color with that of the work piece.
- AS Pik-65 is particularly used for the joining and build up welding of parts made from gray cast iron, nodular cast iron, malleable cast iron and of parts whose analysis is not known.
- Monel alloy core has 65 % Ni / 30 % Cu. It is an ideal electrode for the joining of cast iron pieces to monel alloys, stainless and ordinary steels.
- It can also be used for filling up cavities in castings, or cavities that might form after machining.
- When welding cast iron without preheat, the smallest possible electrode diameter and the lowest possible welding current should be selected to limit the width of the heat effected zone that might occur due to excess heating.
- When welding thick pieces, a preheating to 100-200°C and slow cooling is recommended..
