YAWATA Ni Cast 98 (Machinable Cast Iron)

Clssification : AWS A 5.15 : ENi-CI,  DIN 8573 : E Ni BG 23

Approvals : TIS

Application : Welding and filling up of cavities of cast iron products.

YAWATA Ni Cast 98 is a graphite type electrode with a pure nickel core wire. Weld metal is not so hard and is easily machined. Arc is stable and slag is easy to remove. No preheating is required in general.

1. Use dry electrodes only.  Damp electrodes should be re-dried at  80~120℃  for 60  minutes before use.
2. Remove degenerated layer completely and avoid continuous welding.
3. Deposit short runs and give hot peening at each bead.
4. Preheating and postheating are not necessary in general. However, preheating at 100~200℃ is required for a structure which is apt to cause stress cracks.
