New technology in LNG tank construction

Until recently,semi-automatic welding processes such as gas shielded flux cored arc welding (G-FCAW) were almost exclusively applied using DC welding current.The sensitivity to magnetic arc blow is thus substantial.The development of new high speed digital inverter technology allows AC welding current to be applied to GMAW and G-FCAW.Large Tank Welding Equipment,Automatic Girth Welder Automatic Girth Welder (AGW) (or 3 O'clock Welder) performs x-ray quality horizontal welds up to 20 times faster than standard manual techniques,cutting in-field welding time for storage tanks by up toKOIKE KNOWS TANKS FROM TOP TO BOTTOMThe VUP-MIG is designed for an open arc welding process with a gas shield.Bi-directional welding travel,with controlled speed,self-supporting,hangs directly on tank shell.All components integrated onto the lift column.The column will support all welding equipment,including power source and gas cylinder.Ideal for nickel or stainless plates
