Light weight girth welder AGW-LW available for double sided welding or single sided. Optional galvanized frame or with painted frame. This light weight AGW has an expandable and removable operator frame to fit in the narrow spaces of double wall LNG and flat bottom tanks.
AGW1-LW single sided & AGW2-LW is a double sided Automatic Girth Welder (AGW) 3 O’clock welder built with expandable seating area frame to provide more room for the operators. This design also allows the seating area frames to be removed so the operator can stand on scaffold while operating the AGW on LNG and Flat bottom tanks. It is also built to fit in the narrow space between the outer tank wall and the inner LNG tank shell plate.
- Double wall storage tank welding can be equipped for AC welding or DC welding applications
- Standard AGWI/II-LW by design can weld plate width up to 3.8m without modification, 4.5m wide plate with some minor modifications.
