[MW:23070] centreline crack

Dear gig in,

Cente line crack come in during welding because of following reasons.

1. Your depth to width ratio is high means narrow groove design.
2. There may be high percent of carbon or sulfur or phosphorus in consumable.

Because melting point of sulphur and phosphorus is low, they solidify after sodification of remaining elements.

Thanks & regards.
