Hydrogen controlled, Basic coated Electrode for Non-Machinable weld on cast Iron
CLASSIFICATION : AWS/SFA-5.15: Est (Nr.)
APPROVAL :
CHARACTERISTICS : A hydrogen controlled, medium heavy coated electrode, laying non- machinable weld deposits on cast iron. The electrode needs the components to be pre-heated in case they are heavy and complicated sections. Gives strong and rigid weld joints.
APPLICATION :
1) Suitable to weld mild steel to cast iron parts.
2) Repair works on cast iron where machining is not of importance and primary consideration
RE-DRY CONDITION : Re-Dry the electrode at 150°C for 1 hour.
WELDING PRECAUTION :
1. clean the weld area free of any surface contaminations.
2. For heavy and complicated sections, preheat to minimum temperature of 400° is recommended.
