Procedure

  • To remove fatigue, crack and hard material by using L-801 and to check the crack and undesired material by using DPT. 

  • To provide the base layer by using L-457.

  • To build up by using L-610.

  • Hard facing is to be done by using L-611 min. 2 Layer.

  • To low possible current during welding. 

  • Final inspection transverse fissuring (Hair cracks) across on final beads is OK.
