BBN welding platform is in possession of the welding capacity of the large scale steel structure, duplex steel ship plate,vessel shell and precision sheet metal, There are several welding methods such as submerged arc automatic welding, narrow gap welding, argon arc welding, shielded metal arc welding and plasma welding. The welding material is carbon steel, alloy steel, stainless steel and the non-ferrous metal such as copper, aluminum and titanium, There are more than 2Q) welding equipments, and the SAF plasma welding machine can weld f2.5 meter seam, which renew the record for this model in length. In the meantime, BBN also has H-Shaped Steel Production Line, Edge Planer, Heavy—Duty Rolling Machine, NDT Room, Heat Treatment Furnace, Blasting Room and Other Large-Scale Equipments. Currently, there are many engineers with CSS, LR, special equipment welding certificate.
