Classification：A5.13 / EFe2
 
 

  1. Weld metal is martensite structure and has acceptable machining properties.
  2. It provides good crack resistance and impact and medium abrasion.
  3. It is suitable for repairing drive sprockets, idlers, pulleys, caterpillar bands, crusher rolls, buckets, chains and shafts.

 

Welding Instruction
  1. Dry the electrodes at 300-350°C for 30-60 minutes before use.
  2. Clean up the contaminations on the steel. Keep arc as short as possible.
  3. Take the back-step method to prevent porosity at the arc starting.
