Girth Welder also know as 3 O'Clock Welder and Automatic Girth Welder
The AGW is a self-propelled frame designed to apply efficient horizontal seam welds by means of the Submerge Arc Welding (SAW) Process. Compare with conventional techniques, the AGW reduces the construction rate 25 times and cuts welding time by 2.
