EC1         

According with GB EZC
Corresponding with AWS EC1

Introduction: EC1  is cast iron electrode of low-carbon steel core wire and strong graphitization type coating. The weld can become gray cast iron slowly after cooling. The crack-resistance is normal. AC/DC.

Applications: Perfect choice for repairing the defect of gray cast iron.

Chemical Composition of Deposited Metal (%)

Reference Current (AC, DC+)

Instructions:
1.The electrodes must be baked under about 150℃ for an hour before welding.
2.For some key casting structures receiving stress, impact, etc., this kind of electrodes are not suitable.
3.The flaws on the low rigidity surfaces of little thin section castings can be given repair welding without preheating. However, general weld need to be preheated to 400℃ and given insulation work and slow cooling after welding so that the repaired places are capable of machine work.
