Main Technical Features

• The AGW is a self-propelled frame designed to apply efficient horizontal seam welds by means of the Submerged Arc Welding (SAW) Process. The AGW rides along the upper edge of a large diameter field storage tank while applying inside and/or outside welding. Compared with conventional techniques, the AGW reduces the construction rate 25 times and save lots of welding time.
• AGW-1 is compatible with the traditional construction method (down-top). The frame drives hang on upper edge of the tank.
• AGW-1 is also compatible with lifting jacks method (top–down, also known as jack up construction). The unit is easily converted to drive at ground level on a rail outside and around the tank.This means:it may weld the bottom plate around the tank
• Power required for Lincoln DC-1000 , 46 kW/EA

Standard package includes

a) Heavy duty motorized carriage with frequency driver for speed regulation. ( Two motors drive the frame upper edge of the tank )

b) Control box for speed adjustment: forward, reverse and stop. Digital display in mm/min.

c) Flux recovery system with flux belt assembly.

d) Manual welding head X-Y-Z dimensions slide .

e) Operator seat with tool box.

f) Power source storage: 1300 mm (L)*1200 mm (W) *1400 mm (H).(Put the DC1000 power in it)

g) Power cables: 2.5 mm² @ 3 Nos, 60 m, Control cables, 60 m, Welding cable 120 mm², 60 m, -----When we supply the DC1000 power,we will supply these cables.

h) Several items: wire reel for 60 lbs coil, electric lifting pulley (100 kilograms @ 30 m from the ground), control, lamp and plug-in for electrical tools.

i) Operation Manual and Electric Diagram.

j) One year Warranty

Optional: we want to weld the bottom plate fillet welds, you may choose the Lincoln LT-7 Tractor magnetic device:

Arc Welding Equipment: Lincoln DC 1000, Lincoln Head Controller NA3S, Lincoln Head wire,feeder NA3S, and accessories.

Device for Lincoln LT-7 Tractor is used when is not enough support for both wheels at the rear of the tractor. Magnetic device allow to use LT-7 for apply SAW on external fillet welds on storage tanks with outside diameters larger than 4.8 m and with base plate flange extension over 76 mm

AGW---automatic girth welder

This machine is a self around monving frame beside the girth tank. It is designed to apply efficient horizontal seam welds (adopt Submerged Arc Welding)on large field erected storage tanks.It may ride along the upper tank edge.
