Italian minimill producer and industry innovator Ferriere Nord of Pittini Group is first in operating a 6th generation Danieli billet welder. The new billet welder went into operation at Ferriere Nord in January 2022 during 3-week plant maintenance shut-down. With the experience of more than 30 billet-welder installations in operation since 1997, Danieli engineers came up with a new, patented machine design which, in addition to consolidated quality performances offers improved maintainability. In fact, the innovative design allows shorter cleaning operations, reducing to 50% the time previously required. This new achievement leads to an improved plant yield which, in the Ferriere Nord case, means an increased efficiency of 5%.Furthermore, the welder features a cartridge concept applied to the welding clamps which now can be replaced quickly and easily, allowing off-line maintenance in the workshop instead of onboard. Finally, a new current-control system speeds-up the welding time and improves the homogeneity of the welding joints.Billet welders allow endless rolling by welding head and tails of billets, avoiding crops of heads and tails.
