Danieli Service capabilities in equipment refurbishment with robotic Welding Process extend their benefits to Chinese customers

For fulfilling the customer require­ments to have the chocks refurbished well with competitive price and good quality and short delivery time, Dan­ieli DCS selected the robotic welding process for taking on the chock refur­bishment.

Thanks to its technical know-how of chock refurbishment Danieli Service is servicing with the automatic weld­ing process skill for more and more customers with competitiveness in terms of quality, delivery time and costs.
