Major component of Girth welding machine

A.   Master Frame

1. Master frame of the girth welder is constructed of structural steel and square tube members.

2. Erection Method: Bottom-to-Top.

3. Min Diameter: Φ5.0m.

4. Shell Width: Bottom-to-top 1.5-3.0m.

   
   

   
   

   
   

B.   Dual Motor Drive

1. The dual AC motor design allows for constant travel across the entire tank circumference. When fit up is not quite perfect or there is an uneven surface for the machine to travel, the dual motors will power the machine across the imperfection. This design will reduce the amount of time required to repair weld defects and will decrease the overall tank erection costs. The dual motors are controlled by one easily.

2. Programmable frequency inverter.

C.   Power Source and Wire Feeder

1. The welding equipment supplied is the Miller HDC1500DX control and RAD400 weld head fitted with nozzle and wire rolls. Wire reel（27.2kg）will be supplied with equipment too.

2. Power source : SubArc DC800,CE.

3. HDC1500DX Welding Progress Control.

4. RAD400 Wire Feeder.

   
   

   
   

   
   

   
   

D.   Power Source and Wire Feeder

1. The welding equipment supplied is the Lincoln NA-3S control and weld head fitted with nozzle and wire rolls. Wire reel（27.2kg）will be supplied with equipment too.

2. Power source : DC600.

3. NA-3S Welding Progress Control.

4. NA-3S Wire Feeder.

   
   

   
   

   
   

   
   

E.   Console

The AGW console houses the electrical travel inverter drive and associated control replays it provides a mean of integrated control of all the accessories of the girth welder (e.g. flux vacuum, 220V single phase aux outlet, lamp, flux winch and so on). The console includes all necessary control knobs and switches such as the speed control potentiometer, direction switch, full speed travel switch as well as emergency stop button.
