AGW1-P2
The AGW1-P2 Automatic Curved Plate Welder is an AGW which is also know as a (3 O’clock welder) has been developed to run on a rail for welding out of standard position girth seams on pressure vessels such as Spheres & Digesters.
The AGW Tank welders are a series of self-propelled Automatic Girth Welders (3 o’clock) welding equipment primarily developed for on-site erection of large storage tanks, silos, blast furnaces and similar cylindrical objects. It is available as a single-side version and a double-side version. Usually it is designed to travel on the top edge of the tank shell. As there are different ways of building tanks, one machine in the series is designed to travel on a rail which is temporarily fixed to the shell or on a stand-alone ring outside the shell.
The operator of each machine (if a full size version) rides in a cabin, where he supervises and controls the welding process with the control panel within easy reach. The cabin, whose floor level under the carriage is variable to suit the height of the plate, is built as a cage to give the operator(s) maximum safety and comfort. For weather protection the cage can be covered by curtains. The cabin of a double-side machine is equipped with ladders our an internal frame climbing system and a joining bridge at the top to facilitate for the operators to climb from one side to the other. The top and bridge has guard rails for the safety of the operators.
The girth welder is an automatic welding machine that straddles the tank plate and is used to complete a tanks circumferential weld joints. It’s typically used in a single or double sided configuration. In the single sided configuration one operator is required and welding on one side of the joint occurs. In the double sided configuration two operators are required and welding occurs simultaneously on both sides of the weld joint.
