Supply of pure nickel electrode Z308

Model: Z308 

 Basic parameters 
 Material: C Mn Si Ni Fe Type: cast iron electrode current amplitude (A): 3.2/4.0/5.0 :350-400 mm length 

 Z308 pure nickel cast iron electrode 

 Details: Z308 meet GB/EZNi-1 main component (%) C ≤ 1.00Mn ≤ 0.50 Si ≤ 2.00 S ≤ 0.03 Ni ≥ 95 Fe ≤ 35 
 Z308 welding pure nickel core, strong reduction of the iron coating graphite electrode type, welding, the weld pieces from time to preheat, good crack resistance and processability. Nickel is expensive, should be satisfied in other rods can not be selected. AC and DC. 

 Uses: used thin pieces of cast iron welding and machining surfaces, such as engine blocks, machine guides, gear housing and other important gray cast iron. 
 Features: high toughness, high wear resistance, erosion and wear. Good weldability Abrasive sanding against the rock, extend equipment life 4-8 times. 

 Tensile strength: / m (m) 240-390 HB120-170. 


 Note: 1 subject before welding electrode is about 150 ℃ baking 1h. 
 Welding, the electrode and the workpiece at right angles to maintain a short arc, thin weld, welding bead width of not more than twice the core diameter, to avoid overheating, weld bead length should not exceed ten times the core diameter. Residue removed immediately after welding, and carefully tap the weld metal, and then arc in the weld metal, not to the base metal.
