Automatic Tank Welding
Automatic Girth Welder (AGW)
|
|
The All Time Automatic Girth Welder (AGW) is an automatic equipment applied to reduce the welding time for joining tank courses during field erection.
Each is equipped with welding heads, travel control, flux belt and recovery system so that horizontal (3 & 6' clock direction) can welded.
It straddles the shell plates riding on adjustable flanged wheels, travels at a controlled speed for mechanized SAW.Basic components that make up an AGW are machine frame, welding head(s), controls, flux support belt(s), flux recovery units(s), welding power supply with storage case.

Advantages
Horizontal seam welded by AGW
|
 |
1. Utilize mechanized SAW process to weld storage tank horizontal seams 20 times faster than traditional manual welding processes.
2. Power propelling frame & operator platform allows welder to perform various welding operations in different tank courses with comfort.
3. Provides high quality continuous weld seams around the tank circumference.

Equipment
All Time provides four models of AGW for various types of tank configurations.
AGW1 - for single sided horizontal girth inside / outside welding of large storage tanks with SAW.
AGWII - for double sided horizontal girth inside / outside welding.
AGW LNG – special version of girth welder for double shell cryogenic tanks (e.g. 9%Ni LNG tank)
AGW1D –girth welder with special modular frame for both "Traditional" AND "Jack up" storage tanks welding.
AGW Control with digital speed display, travel speed potentiometer, direction switch, weld / rapid travel control, power on/off, flux lift winch ,flux vacuum on/off and emergency stop. Also connected to the Lincoln welding control for sequencing.
