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.
